Building Services
Space Heating and Cooling
The Claremont Hotel is conditioned using LTHW (wet) radiators and split DX (heating and cooling) systems. A schedule of split DX systems
presently installed in the Hotel is included in the appendices. Radiators are located throughout the hotel (bedrooms, staff rooms, kitchens,
corridors) and split DX systems are located in the lounge, restaurant, boardroom and function rooms. The fuel source for space heating and
domestic hot water is natural gas and controls are manual.
Four gas condensing boilers serve the Hotel, which are located in two separate plant rooms. The boilers in plant room 1 (left side of the
building) serve 24 guest rooms and the boilers in plant room 2 (right side of the building) serve 32 guest rooms.
The boilers are maintained twice a year by Paul Wheeler limited. The newest boiler (Alpha) is 3 years old and the others (Clyde) are 10 years
old. Richard Bool reported that the Clyde boilers require more frequent maintenance, as they are prone to breakdown. One of the boilers was
in the process of being replaced at the time of the audit.
It was noted during the audit that the split DX units in the basement function rooms were running when the area was not in use.
The unit at the back of the right-hand lounge was running at 30°C and the area was overheated. It was assumed that this was due to the area
being open to the reception, which is cooler due to one of the automatic circular doors remaining open, allowing air from the outside to enter
the reception, lounges and sometimes the restaurant.
There are split DX units located in the bay windows, which can sometimes have their vents open. This causes the warm air from the units and
the cold air from the vents to constantly conflict with each other.
In conclusion, public areas are being overheated to compensate for the allowance of cold air entering the building, through window vents and
open doors. Due to the manual controls, units are left on when they are not required.
P a g e | 10 July 2014
Bedrooms were found to be a lot warmer than expected (ranging from 23.5-27.3°C), with an average temperature of 26°C. Guest suite 102 in
particular overheats. Un-insulated hot water pipe work was found with a thermal camera underneath the floor in this room and a sample
image has been included in the appendices. Bedrooms also suffer from solar gain issues. This can raise the room temperature above the 19-
24°C, which most people find comfortable.
Following discussion with Richard Bool it was agreed to carry out an experiment to reduce the ‘RUN’ times for the DHW secondary circulating
pump in plantroom 1 and record the resultant temperature in guest suite 102. The results of the temperature logging are included in the
appendices and it can be seen that the resultant temperature in the room appears to be lower when the DHW pump operating times are
reduced.
It should be noted that the modified DHW operating regime will also benefit the Hotel by reduced energy costs.
The right-hand plant room was overheated. Much of the exposed pipe work recorded temperatures of 51°C. It was noted during the audit that
large areas of pipe work and flanges were not insulated resulting in losses of energy.
A quotation for insulating the exposed pipework in plantroom 2 has been obtained from King’s Thermal Insulation Limited and is included in
the appendices.
There are different heating profiles during the summer and winter months. It was noted that if the weather is reasonable in summer the
heating can be switched off for two months.
Weather compensation controls are presently not installed in either of the two plantrooms. Weather compensation permits the boiler
temperature to be modulated to reflect the outside air temperature e.g. if the outside temperature increases the boiler flow temperature is
correspondingly reduced and vice versa.
A quotation has been obtained from Paul Wheeler ltd to supply & fit weather compensation controls and motorised valves in both plantrooms
and is included in the appendices.
Analysis of the electricity and gas demands for the Hotel over a 24 month period has established that the Claremont Hotel would benefit from
a CHP (combined heat & power) installation and thermal store to serve each of the two existing plantrooms.
P a g e | 11 July 2014
The CHP engines would be installed inside weatherproof enclosures located in the existing courtyards (see appendices) and inter-connected by
insulated pipework and cables with their respective plantrooms.
The suppliers claim that the CHP gas engine is both low maintenance and quiet operation (equivalent to the noise of a domestic washing
machine).
Based upon existing demand figures the combined installations are anticipated to provide approximately 46% of the Hotel electricity
consumption and 82% of the heating demands which translates into an estimated 16% saving in present annual energy costs and carbon
emissions.
Proposals have been obtained from SAV systems limited and details are included in the appendices.
An email received from Manx Gas is also included in the appendices which indicates that various financing options may be available if the CHP
installation was procured through Manx Gas.

Hot Water
Domestic hot water is served from the same boiler system as the space heating. Due to the function of the building there is a high demand for
hot water at certain times of the day (morning and later in the evening). Peak demands from guest rooms served from the RH plantroom have
occasionally outstripped the available storage capacity and resulted in a drop in the hot water temperature in some rooms.
It was noted during the audit that the domestic hot water was running too hot from taps (after 30 seconds the temperature was above 60°C).
This temperature exceeds the health and safety guidance and is recommended to be investigated further.
Energy cost savings may be achieved by replacing the existing hot water calorifiers serving the kitchen and guest rooms with heat interface
units which require no or very little storage of hot water.
Proposals have been obtained from SAV systems limited and details are included in the appendices. It should be noted that the quotations are
for supply & delivery of equipment only. Further investigation work shall be required to determine the feasibility of adapting the existing hot
water distribution systems.
Insulation
The building is constructed of Manx stone which suggests that it has good thermal properties.
The existing loft space is not insulated and is only provided with one means of access into just one section. It is estimated that up to 25% of
energy can be lost through un-insulated roof space. It would be beneficial to insulate the loft space to prevent this potential energy loss.
The pipework installed in the RH plantroom is uninsulated and the ambient temperature in the plantroom is noticeably high as a consequence
of this. A quotation has been obtained from King’s Thermal Insulation limited to insulate the existing pipework and details are included in the
appendices.
P a g e | 14 July 2014
Lighting
There are various lighting conditions throughout the hotel. T8 tubes with high frequency ballasts are located in circulation and staff areas
(store rooms, kitchens, corridors). CFL tubes are mainly located in the corridors leading to bedrooms and LED spots are located in some
bedrooms, with the majority of bedrooms still using halogen spots.
Richard Bool is currently changing the halogen spots in bedrooms for LED spots when required. Richard purchases the new LED spots from LED
Direct on Douglas Promenade, who specialise in low-cost LED light bulbs and offer advice as to what will work in certain rooms.
Some areas, especially public areas (the restaurant, lounges, and function rooms) contain mixed lighting.
It was noted during the audit that rooms were lit in areas that do not gain benefit from artificial lighting (basement foyer, reception). It was
also noted that the CFL tubes in circulation areas were adding to overheating.
All lighting controls are manual, which can result in lights being left on when rooms become unoccupied. This was confirmed during the site
visits.
Proposals for improving the control and energy efficiency of the existing lighting installation have been obtained from Building Evolution
limited and details are included in the appendices.
Ventilation
The majority of the building is ventilated naturally (through open windows and window vents), with mechanical ventilation present in
bathrooms and toilets.
The window vents in the restaurant are located below the split DX units, which conflicts with the outside air temperature resulting in wasted
energy.
Proposals for improving the control and energy efficiency of the existing split DX units have been obtained from Building Evolution limited and
details are included in the appendices.
P a g e | 15 July 2014
Controls
Controls throughout the Hotel are predominantly manual, for heating and lighting. This can cause certain items to be left switched on when
they are not needed, especially in areas that are used late at night.
Space heating (to wet radiators) is controlled through timers, which are manually set by Richard Bool through the plant rooms. The profile can
sometimes change due to the nature of the business. For example, the Hotel caters to flight crews. The air crew can arrive at the hotel late or
very early and request the heating at odd times, due to their work. This results in the timers being overridden to respond to guest’s
requirements.
Proposals for improving the control and energy efficiency of the existing space heating (wet radiators) installation have been obtained from
Building Evolution limited and details are included in the appendices.
Awareness and Training
There is currently one person (Richard Bool) delegated with responsibility for energy usage and cutting costs.
During the site visits, there was little evidence of staff awareness in relation to energy saving. It is recommended that all staff are made aware
of their individual responsibilities when it comes to energy use and energy saving techniques.
It would be beneficial to display “SWITCH IT OFF” notices throughout areas where there is a lot of energy wasted in order to encourage staff to
save energy wherever possible.
An energy strategy is recommended to be developed and implemented to ensure that staff, customers and visitors are energy aware.
P a g e | 16 July 2014
2 Methodology The assessment began with an opening meeting with Ricardo Campos (the Hotel manager) during which Epsilon explained that they had been
commissioned to carry out a full energy audit of the building and services. Ricardo mentioned that energy bills were approximately £100,000
per year for gas and electricity.
Mike Glanfield from Epsilon introduced Ricardo to Kevin Burnell (ISO QA Limited), Nigel Stafford (Building Evolution) and Gemma Burnell (ISO
QA Limited), and explained that he has asked for their expertise as part of the project. Floor plans were supplied to each party, to gain an
understanding of the building layout. Ricardo confirmed that there were no safety or security procedures that could affect their visits.
The ISO QA energy assessment was carried out from 7th March 2014 to 18th March 2014, with specific visits as detailed in the table below. This
included a meeting with the Hotel manager and facilities/maintenance engineer to review billing and building services. Access to all areas was
confirmed and controlled by the facilities/maintenance engineer who ensured that the assessment did not impact on staff and customers.

All zones were measured and a record taken of glazing, doors, walls, floors, ceilings, lighting, heating and cooling including controls. The
building services examined included heating, cooling, lighting and controls. The results of which are included in this report.
P a g e | 17 July 2014
A number of measurements were also carried out for temperature, humidity and lighting conditions. Solar and wind activity were not
measured as conditions were not conducive to gaining meaningful data. Such tests would need to be carried out over a 12 month period to
fully assess the potential benefits of renewable energy.
The data collated following the site surveys was entered into the ‘LifeSpan’ Simulated Building Emissions Model software to produce the
building emissions results (see executive summary).
P a g e | 18 July 2014
3 Site Details The Claremont Hotel is based in one site on the Douglas sea front, over five floors. The use of each floor is detailed below:
Basement – Function rooms, storerooms, toilets, plant rooms, meter cupboards and a food preparation area
Ground Floor – Reception, lounge area, toilets, ‘Coast’ restaurant and kitchens including storerooms
First Floor – 18 en-suite bedrooms
Second Floor – 19 en-suite bedrooms
Third Floor – 19 en-suite bedrooms
Due to the nature of the business, the building is occupied 24 hours a day, 7 days a week. All bedrooms contain various facilities for guests to
use during their stay, including coffee machines, kettles and televisions with DVD players. There is no ‘on site’ car parking facility for guests due
to the location of the Hotel.
The Hotel was originally five separate buildings. It is constructed with solid Manx stone and east-facing with two elevations exposed to the
external environment. The north and south elevations are connected to conditioned spaces.
Employees of the Hotel are responsible for cleaning and securing the building and Richard Bool takes care of maintenance issues, including
energy-saving initiatives.
The Hotel is not equipped with a laundry, therefore this function is outsourced. There are however two kitchen areas. One large kitchen serves
the restaurant and the other is located in the basement, serving the basement function rooms when they are in use. The function rooms are
used for business conferences, parties and weddings, so can be occupied during the day and night according to the booking arrangements.
P a g e | 19 July 2014
Meters
There are three gas meters used to calculate consumption and charges. They are located in the right-hand side of the basement area and at
the back of the building. One meter serves the kitchen gas demands and the other two serve the gas boilers located in the two plantrooms.
There are two electricity meters located at the rear of the building in a separate locked area. It was noted during the audit that they consisted
of an analogue meter and a poly-phase meter. One meter records the total electricity consumption of the Hotel and the other serves as a
check meter.
To gain a better understanding of how much electricity is consumed at different times of the day and week, it is recommended to fit ‘Energy
Eye’. This will give half-hourly data on the amount of electricity being consumed and permit detailed analysis of electricity consumption.
Catering
There is a large amount of catering equipment located in the hotel. This includes refrigerators, ovens, cookers, a manual on/off ventilation
system, dishwashers, hot water urns and a large cold store.
A site survey of the Hotel catering areas was carried out with John Purvis of Design Catering limited but very few opportunities for energy
saving measures were identified beyond encouraging staff to switch off appliances when not in use.
Due to the nature of catering there are not a lot of options available to reduce consumption in this area. However, energy waste can be
reduced by ensuring that equipment is maintained regularly and that energy efficient equipment is considered when items require
replacement.
Power Factor
There was no available information to gain an accurate measure but it was reasonable to assume, based on the equipment and processes
carried out that it should be no less than 0.90. However, it is recommended to consider fitting ‘Energy Eye’ made available from Manx Utilities
as this will enable an accurate measurement of power factor to be taken. Manx Utilities do not presently impose a penalty on customers who
have a poor power factor.
P a g e | 20 July 2014
Electricity ASC (agreed supply capacity)
The Claremont Hotel has a KVA agreement with the Manx Utilities of 130KVA per month. A review of the electricity bills over the past two
years confirmed that this was well within the agreed capacity. Therefore, no penalty charges appear to have been incurred. However, it was
pointed out during the investigation that an application has been made to the MEA to increase the agreed supply capacity to cater for split DX
(heating & cooling) units proposed for installation in 16 seaside facing guest rooms.
Tariffs and Charges
The business is on the standard commercial electricity tariff of 13.53 pence per unit of electricity consumed. The Hotel will also benefit from
the prompt payment discount of 2.5% and a direct debit discount of £1.00.
Solar Gain
Solar gain may be an issue in some bedrooms facing the West elevation, causing some of the guest rooms to overheat at certain times of the year. By applying solar film to existing glazing the overheating issues could be mitigated. This measure will also reduce the cooling load on the seaside facing rooms proposed to be fitted with split DX heating & cooling units and keep electrical running costs to a minimum.
Renewable Energy
Owing to the location and topography of the building the ‘LifeSpan’ SBEM data did not suggest that the building would benefit from employing renewable technologies.
P a g e | 21 July 2014
4 Utilities Analysis It was ascertained that there are two main utility sources used within the building; electricity and gas. Grid electricity is used for lighting and electrical appliances whilst natural gas is used for space heating, domestic hot water and cooking.
You will see from the following table how much of each energy source is currently being used.

The SBEM report indicates that a similar size building with the same business use should be consuming 80% gas and 20% electricity. From the above table it can be seen that the Claremont Hotel is using proportionally more electricity than the benchmark building.
During the audit, it was noted that some electrical appliances were left on when they were not required (e.g. split heat systems, lights, televisions, computers, etc.). Awareness amongst all staff regarding energy consumption and waste is recommended to improve this situation.
P a g e | 22 July 2014
5 Benchmarking We have used information supplied by the UK Government to compare the Claremont’s present building emissions rating (kgco2/m2) against the benchmarks set by Energy Efficiency Best Practice Guides for Hotels.
The results (see chart in Appendix C) indicates that the Claremont Hotel is above average efficiency with potential to improve, specific measures are detailed elsewhere in this report. However, although the consumption index may be better than average, the cost of the consumption is significantly higher due to higher energy costs on the Isle of Man.

7 Staff Issues Richard Bool attended site visits to answer any questions that we had and help us gain access to certain areas.
During these visits Richard informed us that he often has issues with the boiler flow temperatures. The temperature must be set quite high (usually 65°C) to compensate for significant drops during peak periods (early morning and evening).
Implementing weather compensation controls in both plantrooms should help to address temperature control issues and enable energy savings to be achieved for heating the Hotel.
Richard mentioned that when light bulbs in bedrooms require replacing they are replaced with LED spots to save energy. Currently, this only happens as and when required.
The Hotel currently has issues with staff leaving items on when they are not required, especially the split DX heating & cooling units in the function rooms. Formal awareness training for all staff, relating to energy issues, and signage around these areas to remind staff to “switch off” after use would help alleviate this problem.
Richard is very proactive in reducing energy consumption but appears to have limitations on his budget. He was extremely helpful and valuable to this energy audit.
The meetings with Richard confirm that the company is located on the lower levels of the energy management matrix and there is room for significant improvement in training and staff awareness of energy management and waste.
8 Funding and Government Support The business has taken advantage of the Business Support Scheme grant of 50% for this audit and can now consider looking at the Green Loan Scheme (Appendix B) attracting up to £20,000 interest free loan over four years. Payable in four annual instalments allowing savings to be generated prior to payments made.
The government also funds environmental management systems (ISO 14001) through the BSS which can be used to reduce waste streams including a continued focus on energy consumption.
P a g e | 25 July 2014
9 General Comments Energy Policy:
There is no formal energy policy within the Hotel.
Organising:
At present there is no accountability for energy consumption but Richard Bool does make changes where he can to attempt to save energy and reduce costs.
Training:
There is no evidence of staff training for energy management or energy saving opportunities.
Performance Measurement:
The company currently carries out checks on invoices. There are no procedures in place to regularly monitor energy consumption.
Communicating:
There are no communication channels within the organisation in relation to energy management, including the promotion of energy related issues.
Investment:
There are low cost measures in place with small actions happening, such as light bulbs being changed as and when required.
We would recommend implementing a five-year strategic plan prioritising investment based on payback.
P a g e | 26 July 2014
It is important to have a formal energy policy as it will communicate the company’s commitment to energy management. The policy needs to have the agreement and commitment of senior management. Without this commitment targets are unlikely to be reached, and lack of support could prevent the necessary changes being made within the organisation.
An Energy Policy should:
Raise awareness and provide the basis for action in the workplace.
Stating targets and timescales for achievement.
Provide information on how these targets are to be achieved (this could be in the form of an action plan).
Have an ongoing review which will highlight whether goals have been successfully achieved.
An Energy Policy should include:
A statement of commitment from senior management – this should be signed by the most senior person in the organisation.
A plan of implementation – details of how the policy objectives will be met.
Details of everyone’s involvement – this should make everyone’s responsibility and involvement clear.
Applicability – this defines which parts of the organisation are covered by the policy. Once an energy policy has been agreed and put into place this will help improve the other areas addressed by the energy management matrix such as Organising, Performance Measurement and Communicating.

10 Energy Saving Initiatives Energy Policy
Having a formal written energy policy enables a company to effectively monitor their energy usage so that they can make informed decisions to make changes.
Staff Awareness Training
Staff members are important in saving energy so they must be made aware of wastage areas and be trained to operate equipment and controls correctly. Motivate staff – ask their opinions and encourage them to review their own working practices.
Energy Efficient Lighting
By installing up to date energy efficient lighting you can improve the working environment and significantly reduce energy costs.
Timer devices
Savings can be made by using timer sockets as they can be used on equipment that has occasional use but may be left on standby when not in use, such as visual and audio equipment.
Recommendations, Comments, General Advice (general advice for saving energy at work)
Heating & Cooling
Set your radiator or thermostat to reasonable levels. The aim is 21 degrees. Ensure radiators are not blocked by furniture or files, as they will absorb the heat. If it gets too hot in the winter, don’t open a window; try turning down the radiator first. Ensure all extractor fans are off overnight and when not required. Don’t leave doors open between areas of different temperatures. Do not use portable heaters. If it’s too cold report the problem to management. Keep doors and windows closed in air-conditioned areas. If you don’t you’re letting the cool air escape requiring further cooling.
P a g e | 28 July 2014
Lighting
Try to use as much natural light as possible and ensure windows are kept clean. Switch off lights whenever you leave a room (toilet, meetings, lunch and evenings). Between your colleagues make sure the last to leave in the evenings is responsible for turning off all lights.
IT Equipment
Activate your PCs Power Saving Device. Switch off computer screens when away from your desk (especially during lunch and meetings) and turn the whole PC off at night. Do not switch on computers and printers until you need them. Make sure you share printers between colleagues. Switch off photocopiers and printers at night. Purchase electrical equipment with a high energy saving value.
Kitchen
Regularly defrost fridges to avoid wasting energy. You should also check the seals on your fridge/freezer to ensure that warm air is not getting in – the seals should be tight enough to hold a piece of paper securely when closed. Fit a SAVA plug to the fridge: when the thermostat on the appliance switches on the motor to pump the refrigerant around the system, full power is required to start the motor. However, once the motor is running full power is no longer needed. The SAVA plug senses this and reduces the flow of electricity to meet actual requirements. SAVA plugs reduce running costs 20%. SAVA plugs cost £20.
Linked-In
Epsilon posted a discussion on the Hotels Group and Hospitality Group on the “Linked-In” social media website appealing for contributions to compile a “TOP TEN LIST OF ENERGY SAVING STRATEGIES” for the Hotel & Hospitality industry. A total of 31 replies were received and are reprinted in the Appendices.

11 Appendices (Appendix B) 0% Green Business Loan Scheme Investing in energy efficient equipment makes sound business and environmental sense, especially with the easy, affordable and flexible 0% green business loan scheme offered by the Department of Economic Development for Isle of Man businesses. The scheme has been designed to provide flexible financing options to all types of organisations seeking to make their operations more efficient and lower their energy costs. The scheme offers a loan of 100% towards the cost of projects that improve energy efficiency and can be arranged from £1,000 up to a maximum level of assistance of £20,000 per project. New, more efficient equipment should lower energy bills and with payments calculated so that they can be offset by the anticipated energy savings, the financing option is designed to pay for itself. Suitable projects for the scheme include lighting/lighting controls, compressed air systems/controls, variable speed drives/motors, heating/heating controls, insulation upgrades, heat recovery, pipe insulation and solar thermal systems. The repayment period for the loan is up to a maximum of 4 years with equal repayments due annually at the end of each year. The Department of Economic Development may provide assistance to an eligible business where, in its opinion, the eligible business undertakes an economic activity in the Island. Eligibility for the 0% green business loan scheme is open for all business sectors and where projects will involve energy efficiency improvements in Isle of Man business premises. The Department of Economic Development will only consider an application for a 0% green business loan that has not been submitted for funding from another Government financial scheme for the same project. The 0% green business loan scheme is at the discretion of the Department of Economic Development and each project will be assessed on its potential to deliver real energy savings with preference given to projects that provide the greatest reduction in CO2 emissions thereby assisting the Government in achieving its energy policies. In order to apply for a 0% green business loan, we require a completed Application for Financial Assistance – F101e form signed by a director/principal on behalf of the company and the necessary supporting documentation. Supporting documentation must include a thorough project report detailing expected energy savings, background information on the company and audited accounts for the last three years (unless a start-up venture, then 3 years forecasts must be provided).
P a g e | 31 July 2014
Further detailed information on all aspects of the 0% green business loan scheme can be obtained by contacting [email protected] or 01624 682367. Note: The Department may wish to take security on the assets of the company to protect any financial assistance provided. Assistance cannot be considered retrospectively for items of expenditure which have already been purchased. The applicant should be aware that the details of all financial assistance paid out under the scheme will be published in an annual report prepared by the Department of Economic Development which will also be laid before the Isle of Man Parliament.

1 ScopeThe aim of this report is to provide the client with options for allowing energy savings throughout different areas of the hotel. It discusses the problemsnoted with regards existing lighting, heating and air-conditioning and identifies a number of opportunities for improvement. In some cases, while thesolutions suggested offer improvements in energy usage, they also as a consequence provide improved guest comfort and convenience as well asopportunities for improvements in overall building management.
There are many different areas of the hotel and of course many areas where we can search for energy saving opportunities. Unfortunately, it has not beenpossible to carry out a 100% top to bottom survey and analysis of the hotel, but it has instead been decided to focus on a number of key areas. These areasare, guest rooms, basement functions rooms and other basement rear areas, ground floor lounge and restaurant.
2 Executive Summary2.1 Guest RoomsLooking at the present situation, the guest rooms have a very basic form of heating control with Thermostatic Radiator Valves (TRVs) on all radiators andthen heating turned on and off with a time-clock in the boiler room. Heating of rooms is therefore purely on a time bases and in no way linked to the actualoccupancy state of the rooms. There are therefore good opportunities for energy saving by linking the heating of rooms to occupancy.
As we are aware that the hotel management are probably going ahead with installing air-conditioning in 18 rooms we have taken this scenario intoconsideration.
Two basic solutions were looked at, a standalone solution and a networked BMS solution.
2.1.1 Stand Alone SolutionThe first is a standalone solution where each room has wireless controls for air-conditioning linked to the keycard switch.
The second standalone solution is where both air-conditioned rooms and rooms with radiators have wireless controls controlled by a keycard. The roomsheating or cooling is therefore dependent on room occupancy. With this situation the boiler room time-clock still determines when all radiator heating is onor off but the amount of heat entering a room is controlled by the use of the keycard.
In this standalone scenario air-conditioning, which we presume will also provide heating, can only be enabled or disabled by the key-card meaning that air-conditioning is turned off when the room is unoccupied.
Building Evolution Ltd Claremont Hotel Energy Report July 2014

2.1.2 Room Networked BMS SolutionIn this solution all rooms heating or cooling is controlled through a Building Management System which also controls the heating pumps in the boiler rooms.Greater savings are possible with this solution as there is far better control of heating and air-conditioning, plus the system is linked to the hotelmanagement Fedelio booking system.
2.1.3 Cost and SavingsFirstly, it is important to note that all calculations are based on certain assumptions, the most important of which is the amount of Heat Gain i.e. heatgenerated by the building other than through the heating system. Following conversations with Epsilon Consultants and from room temperature readingsprovided from ISO IOM Ltd it is thought that heat gain is relatively high and so a figure of 7.5 degrees has been used. However, in order to achieve a moreaccurate Heat Gain figure a more extensive survey and building model would need to be carried out.
When comparing savings we can firstly compare with the present situation where all room have radiators on the time-clock and also compare against amore likely base scenario which we call Option 1 where the hotel has 18 rooms with air-conditioning and 36 rooms still on the present system.
Option 1 is the standalone scenario where there is no keycard system and we presume that the air-conditioning would be left running constantly.
Option 2 is the standalone scenario where rooms with air-conditioning have a keycard system but remaining rooms with radiators just stay on the presenttime-clock.
Option 3 is the standalone scenario where all rooms have a keycard to control radiator heating and air-conditioning.
Option 4 is where all rooms have a keycard and the rooms are networked onto a BMS controlling radiators and air-conditioning.
Due to the fact that gas meter readings are for the domestic hot water and heating combined and that we have no information on the actual gas used byjust the heating we cannot provide savings in terms of pounds. This has been discussed with Epsilon Consultants who will provide their estimations offinancial savings in their report.

2.2 Basement LightingThe hotel has already made a start in replacing some lights with LEDs which would have helped reduce energy costs. However many areas could still beupgraded to LED to cut energy costs further.
Lights in many areas are often left switched on when no one is using the room and in some areas this is on 24 hours a day 365 days a year.
Proposals for reducing lighting energy costs and also providing better control are suggested.
2.2.1 Rear Staff areasDuring the original hotel conversion in many areas there was no major rewiring of lighting circuits to take into account new room and corridor layouts. Theresult is that a number of separate rooms and corridors share the same switched lighting circuit. So for example if a corridor light is on then so are the lightsin one or more store rooms.
It is therefore proposed to install occupancy sensors in all areas and replace all lighting with LEDs.
Building Evolution Ltd Claremont Hotel Energy Report July 2014

An annual saving of £1353 has been estimated.
Budget cost for this solution is: £5159
Estimated payback period is: 4 years based on a constant electricity price of 13.53 pence per kWh over that period.
2.2.2 Function RoomsSome lights in the functions rooms have been replaced with dimmable LED lights, however, the existing lighting system is unable to provide proper dimmingfor LEDS and so lights have a tendency to flicker. This causes difficulty for staff and guest when trying to adjust them.
Fluorescent trough lights in the function reception area could be replaced with LED strip lights because these are only switched on and off. However,because trough lighting in the main function rooms need to be dimmed these cannot be replaced with LED strip lights because the existing lighting systemwould not be able to do dim them. It is therefore proposed to change the lighting system to a more modern system that allows dimming of LED lighting andreplace existing fluorescent trough lights with White LED Strip Lights.
The system would also include occupancy sensors for turning on lights when people are just passing through or only in the room temporarily.
The system could also be controlled remotely through a graphical user interface on a tablet, smartphone or PC web browser. So new lighting scenes caneasily be setup and stored by staff for different events.
Although not an energy advantage the new system also has the capability, with no additional costs in control gear, of being able to provide colour changingeffects to RGB coloured strip lights if these chosen in some areas instead of white.
Guest toilets and corridors would be put on occupancy sensors however one guest corridor which includes the WCs lobby area could be linked with thefunctions rooms so lights are held on during a function.
For this solution it is estimated that an annual saving of £2093 could be achieved.
Budget costs are £12,500
Payback period is estimated at 6 years based on a constant electricity price of 13.53 pence per kWh over that period.
2.3 Basement Function Rooms Air-conditioningThe air-conditioning in the basement function rooms is occasionally left on. There is a separate time-clock but this can keep the air-conditioning runningwhen no-one is using the function rooms. The proposed new control system for lighting in the function rooms could also be used to turn off air-conditioningwith the occupancy sensors and turn it on and off through the tablet, smartphone etc.
The budget cost for this would be an additional £200 on the cost of the lighting control system.
Building Evolution Ltd Claremont Hotel Energy Report July 2014

2.4 Ground Floor Lounge and Restaurant2.4.1 LightingLighting in the main restaurant is LED controlled by a good lighting control system designed for dimming LED lights. Lights are turned on and off by staff. Itis not known whether there are times when lights are left on when the restaurant is closed, however, lights in the widow bays are on even when the area isalready very bright with incoming sunlight.
Further study could be carried out to look at linking these lights with light level sensors therefore only turning them when natural light drops below a setthreshold.
2.4.2 Air-conditioningAir-conditioning is on a time-clock and can be turned on and off manually. Due to their age it is not possible to interface these units with a BMS system toprovide improved control capabilities, other than just to turn on and off. In fact, although not an energy issue, according to Mitsubishi the units are very oldand will no longer be supported for spare parts after January. We would therefore suggest that the hotel confirms this themselves with their air-conditioning maintainer.
3 Detailed ReportThis part of the report discusses issued raised in the Executive Summary but provides greater detail.
3.1 Guest Rooms Stand Alone Solutions3.1.1 Heating Control for Rooms with Radiators only.3.1.1.1 Current SituationAt present, all rooms are heated by hot water radiators fed from one of two boiler rooms in the basement. A time-clock fitted to the control panel in theboiler room determines when the rooms are heated. All radiators in guest rooms have Thermostatic Radiator Valves (TRVs) fitted which need to bemanually adjusted in order to regulate the room temperature. The time-clock settings are sometimes adjusted to take into consideration additional guestrequirements, e.g. flight crew arriving very late or very early. Time-clocks are also adjusted in the summer to try and save energy.
3.1.1.2 ProblemsThis type of heating control is very basic as room heating is based only on a time basis rather than an individual demand basis. As it is very unlikely that aroom TRV is turned down when a guest either leaves the room or checks out of the hotel the TRVs are therefore kept in a constant setting. This will be thesetting that gives the warmer comfort room temperature. This means once the time-clock has put the heating on the room will be heated to the comforttemperature regardless of whether the room is occupied or even checked out.
Building Evolution Ltd Claremont Hotel Energy Report July 2014

3.1.1.3 NeedsA more economical method of controlling the heating in guest bedrooms is required. One that prevents rooms from being heated needlessly when a guestis not in the room but also one that can automatically put the room to the comfort temperature when the room is occupied. Also, as some guests vary inwhat they feel is a comfortable room temperature, a simple method for them to make slight adjustments to the room temperature is required, so providingadditional comfort and satisfaction.
3.1.1.4 SolutionIn order to address the needs stated a wireless heating control solution is proposed. This solution treats each room as a standalone system for controllingand regulating the room temperature based on room presence or absence through a Keycard. A wireless solution has the advantage of minimising anyadditional wiring therefore reducing installation costs and room down time during installation. Also, the wireless devices selected will utilize a uniqueenergy harvesting technology meaning that they will be able to operate without the need for batteries and therefore reduce maintenance requirements.
Each room would have:
(1) A wireless Key Card Switch fitted inside the room.(2) A wireless room Temperature Sensor with dial to allow the user to make a simple manual offset to a default Comfort Temperature.(3) A wireless proportional controlled Radiator Valve Actuator, which replaces the TRV, and opens or closes the radiator valve between 1 and 100%.
This device is battery powered.(4) A wireless Message Server. This device is mains powered.
3.1.1.5 OperationWhen a guest enters the room they place the room door Key Card into the Key Card Switch. The Key Card Switch sends a wireless message to the MessageServer indicating that the room is occupied. The Message Server will then set the room to the occupied (i.e. Comfort) setting and send a wireless signal toadjust the radiator valve so bringing the room to the required Comfort temperature. The Message Server will constantly determine the proportionalcontrol value to be sent to the radiator valve actuator by comparing the room temperature value received from the temperature sensor and the pre-programmed Comfort Set Temperature (e.g. 21 degrees). It also takes into account any offset to the Comfort Set Temperature sent from the user dial onthe Temperature Sensor.
When the guest leaves the room and takes the Key Card out of the switch, the Message Server sends a new control value to the radiator valve actuator toput the room to a Lowered temperature, e.g. 19 degrees.
3.1.1.6 Point to NoteIt should be noted that with this standalone solution the time clock in the boiler room still controls the pumping of hot water around the building, howeverthe controls in each room will determine how much heat is put into the room. If all rooms are at their required set temperature and the time clock is still on
Building Evolution Ltd Claremont Hotel Energy Report July 2014

then the hot water will still be circulated around the system although not passing through room radiators and heating the rooms. Some heating losses aretherefore still occurring.
3.1.2 Heating Control for Rooms with Air-Conditioning3.1.2.1 Current SituationIt is understood that the Hotel management are seriously considering having air-conditioning installed in certain rooms. This will provide guests withgreater comfort especially in summer where front facing rooms with larger windows get greater solar gain and may tend to overheat.
3.1.2.2 ProblemWhile the primary concern for the hotel management is guest comfort they have accepted that this would come at the expense of greater overall electricitycosts in running the air-conditioning.
It is possibly that when a guest leaves the room they will leave the air conditioning running even though they may be out of the room for many hours, plus arooms air-conditioning could be left running even if the room is checked out and may not have a guest booked till the following day.
3.1.2.3 NeedsA solution is therefore required that can ensure that the energy usage by the air-conditioning is reduced when the room is unoccupied. So saving on air-conditioning running costs.
3.1.2.4 SolutionThe solution proposed assumes that any room with air-conditioning installed will have its room radiators shut off completely and that heating of the roomwill only be carried out with the air-conditioning unit. Also, it is presumed that the air-conditioning unit will have its own control panel or remote control foruse by the room occupant.
In order to meet the needs stated above we wish to propose a simple wireless control solution that utilizes the same Key Card Switch as previouslyproposed for the control of room heating.
Each room will have:
(1) A wireless Key Card Switch fitted inside the room.(2) A wireless to Air-Conditioning interface unit.
3.1.2.5 OperationWhen the Key Card is fitted into the Key Card Switch the Key Card Switch sends the wireless “Room Occupied” message to the air-conditioning wirelessinterface. This enables the air-condition unit and allows it to be turned on from the control panel.
When the occupant leaves the room and removes the Key Card a “Room Unoccupied” message is sent that disables the air-conditioning unit.
Building Evolution Ltd Claremont Hotel Energy Report July 2014
10
3.1.2.6 Point to NoteThe room temperature is maintained purely by the air-conditioning and is only done when the Key Card is in the Key Card Switch.
Also, following correspondence received from the prospective Air- Conditioning installation company we note that that they intend to use the Mitsubishirange with a room indoor unit model number PEFY-P32VMS. However, I have been informed by Mitsubishi that this model number would not becompatible with the wireless to Air-Conditioning interface unit proposed. They say that in order to have compatibility the latest model number should beordered which would be model PEFY-VMS1.
3.2 Networked Rooms - Building Management SolutionA building management system (BMS) offers a further enhancement on the stand-alone solutions described above. It allows the separate rooms andbuilding functions such as heating and lighting to be controlled in an even more energy efficient way so further reducing energy costs. It will also offeradditional benefits such as central control and monitoring of rooms, monitoring of building energy performance and automatic fault reporting, from anycomputer, tablet or smartphone, from either inside or outside the building.
3.2.1 BMS InfrastructureA BMS infrastructure would basically consist of:
(1) A single cable (Bus Line) running along each floor through the corridors but in most cases not entering rooms. On each floor the bus line wouldterminate in an enclosure in a store room.
(2) Along the bus cable would be a number of wireless gateway devices which allow bi-directional communication with wireless devices in nearbyrooms.
(3) A separate BMS network switch located in the IT room behind ground floor office(4) A BMS controller located in the IT room and connected to the BMS switch(5) Network cable linking the switch to the bus line on each floor.(6) A bus line connecting the boiler rooms in the basement along with a network cabling linking to the BMS network switch.
3.2.2 BMS - Heating Control for Rooms with Radiators only3.2.2.1 SituationThis is an alternative to the standalone solution for rooms with radiators only.
3.2.2.2 ProblemsThe standalone heating solution previously discussed goes a long way in reducing energy costs in guest rooms. However, certain wastage would still occur.As mentioned earlier, if all rooms are at their required set temperature and the time clock is still “On” then the hot water will still be circulated around thesystem although not passing through room radiators. This is a waste of energy.
Building Evolution Ltd Claremont Hotel Energy Report July 2014
11
Also, with the standalone solution, the Key Card can only put the room temperature to two different settings, that is Comfort Temperature (e.g. 21 degrees)when occupied and a Lowered Temperature (e.g. 19 degrees) when unoccupied. If the room is not in use for a day or more then room is still being kept at ahigher temperature than is probably necessary.
3.2.2.3 NeedsA method is required for only allowing hot water to be circulated around the building when room heating demand requires it rather than purely on the timeof day.
Also, if two lower temperature settings were possible for when the room is checked out and when the room is out of use for a longer period, e.g. formaintenance or decoration, then even greater energy saving could be achieved.
3.2.2.4 SolutionA BMS system would monitor all individual room heating controls and provide control to the boiler room so that hot water is circulated on a heat demandbasis rather than on a time demand basis.
The BMS could also interface with the Fidelio Hotel booking system so that Fidelio can send a check-in / check-out message to the BMS. The BMS can thenautomatically set a room into a lowered Standby temperature of say 17 degrees.
As the BMS would also provide a user interface that can be viewed over any computer web browser it would also be possible for the room temperature andsettings to be monitored and controlled staff, e.g. perhaps to respond to guest’s requests or inquiries on the room temperature or maybe to set the roomto a Frost setback temperature if the room is out of action for a much longer period.
A further advantage is that the battery powered radiator valve actuator is capable sending a wireless message when its battery is getting low. This could beused by the BMS to alert maintenance staff, e.g. via email.
Rooms would have the following:
(1) A wireless Key Card Switch fitted inside the room.(2) A wireless room Temperature Sensor with dial to allow the user to make a simple manual offset to a default Comfort Temperature.(3) A wireless proportional controlled Radiator Valve Actuator, which replaces the TRV, opens or closes the radiator valve between 1 and 100%. Battery
powered.(4) For some rooms it may also be necessary to add a wireless repeater to ensure adequate wireless coverage.
3.2.2.5 OperationFrom a room occupant point of view the room temperature is controlled in the same way as with the standalone solution, i.e. by use of the Key Card andmanual adjustment of the dial on the temperature sensor.
Building Evolution Ltd Claremont Hotel Energy Report July 2014
12
From a technical point of view however the difference is that all wireless devices communicate with the main BMS controller via the wireless / busgateways in the corridors and the BMS takes over the regulation of all room temperatures.
3.2.2.6 Point to NoteIn the BMS solution there is no need for the Message Server that resides in each individual room in the standalone solution. This is because the one BMSController does the job of multiple Message Servers.
In order to control heating pumps from the BMS a modification to each of the existing boiler room control panels is required.
Initial investigations have shown that there is some documentation on just one of the panel’s wiring but even this looks to be inaccurate. Furtherinvestigation is therefore required to determine the exact wiring of the boiler room.
3.2.3 BMS - Heating Control for Rooms with Air- Conditioning3.2.3.1 SituationThis situation is an alternative scenario to the standalone solution for rooms with air-conditioning only as described in 3.2.
3.2.3.2 ProblemThe standalone air-conditioning solution described in 3.2 goes a long way in reducing energy costs in guest rooms. However, certain wastage would stilloccur. On particularly warm days in summer the room temperature could get quite warm if the air-con is turned off and it would therefore use a lot ofenergy in trying to re-cool the room to a Comfort temperature once occupied again.
Also, as it is assumed that the air-conditioning will also provide the heating then if it is turned off then the room could be allowed to cool down too much.
Also in standalone solution, the wireless/ air-conditioning interface unit only allows the Key Card switch to enable or disabled the air-conditioning unit.Once enabled it still needs to be turned on from the air-conditioning user control panel. This is inconvenient for the guest and they may not realise the air-conditioning is turned off at the panel.
3.2.3.3 NeedsAs well as the Comfort Setpoint, the air-conditioning is capable of being put into two additional temperature settings of Standby and Economy.
A means is therefore required to automatically set the room to these other Setpoints rather than turning the air-conditioning off completely.
3.2.3.4 SolutionThe Mitsubishi air-conditioning system being considered has its own data communications network to allow the indoor units and controls to communicatewith the outdoor unit.
Building Evolution Ltd Claremont Hotel Energy Report July 2014
13
Figure 1. Simplified diagram of the proposed Mitsubishi Air-Con System
By connecting the Mitsubishi network to the BMS all control signals would become available on the BMS which -would allow the BMS to control andmonitor the air-conditioning and integrate its control with devices not on the Mitsubishi system e.g. Key Card Switch and Fedelio.
To achieve this an additional gateway device between the Mitsubishi network and the BMS network is required.
Building Evolution Ltd Claremont Hotel Energy Report July 2014
14
Figure 2. Mitsubishi system connected to a BMS system.
(Note. BACnet is just the name of the communications protocol used on the BMS)
Each room will have just require a wireless Key Card Switch.
The BMS would have the interface with the Fedelio system as well as the user interface on any computer.
3.2.3.5 OperationThe air –conditioning is kept switched on. The Fedelio system will provide the “Checked-in” / “Checked –out” status to the BMS. The BMS will then set theroom air-conditioning to the Economy Setpoint or the Standby Setpoint.
When the guest inserts the Key Card the Wireless Key Card Switch communicates with the BMS via the Wireless/ Bus Gateway in the corridor. The BMSthen puts the room air-conditioning into the Comfort Setpoint.
Building Evolution Ltd Claremont Hotel Energy Report July 2014
15
When the guest removes the Key Card the BMS will put the air-conditioning to the Standby Setpoint.
For example, the cooling Setpoints may be as follows:
Comfort Cooling – 23 Degrees
Standby Cooling – 25 Degrees
Economy Cooling – 27 Degrees
As the air-conditioning also provides heating, the heating Setpoints will also be altered e.g.
Comfort Heating – 21 Degrees
Standby Heating – 19 Degrees
Economy Heating – 17 Degrees
Building Evolution Ltd Claremont Hotel Energy Report July 2014
16
Figure 3. Heating and Cooling Setpoints For Air-Conditioning (for Night-time mode read Economy)
The result is that the air-conditioning will not be allowed to waste energy by being left running at the Comfort Setpoint when the room is unoccupied, plusbecause the air-conditioning is not turned off the room will also never be allowed to get too hot when it is unoccupied.
Instead the guest will enter a room which is already starting to be cooled and will more quickly reach the Comfort Setpoint once the Key Card is used.
There will also be the possibility of turning the room air-conditioning off through the BMS.
3.2.3.6 Point to NoteIn the Standalone solution for rooms with air-conditioning, i.e. if no BMS, the Key Card controls the air-conditioning via a wireless to air-conditioninginterface located in each room and this only allows the Key Card to turn the air-conditioning on or off.
With the BMS solution the wireless to Air-conditioning interface is not required.
Building Evolution Ltd Claremont Hotel Energy Report July 2014

3.2.4 Lighting Control3.2.4.1 Current SituationGood efforts have already been made to reduce the lighting energy costs, with all rooms now having their lights replaced with LED.
The hotel room’s lighting have been traditionally wired e.g. with no intelligent or semi intelligent lighting control to take into account presence or absencein a room.
3.2.4.2 ProblemsWhile replacing lights with LED will have had a major impact on lighting energy costs there are still times when energy is being wasted. This is mainly whenguest or staff leave the room but leave lights turned on.
3.2.4.3 NeedsA simple solution is required to prevent guests or staff from leaving lights on when they leave the room. However, any solution needs to minimiseinstallation costs and room downtime during installation.
3.2.4.4 SolutionIn order to address the needs stated we wish to propose a simple wireless lighting control solution that utilizes the same Key Card Switch proposed for thecontrol of room heating / air-conditioning. Also required will be a small wireless switching actuator that will be installed in line with the main incominglighting circuit.
3.2.4.5 OperationWhen the Key Card is fitted into the Key Card Switch the Key Card Switch sends the “Room Occupied” message which is received by the wireless switchingactuator. The actuator switches and enables the main incoming lighting circuit. Room occupants will then turn lights on and off as normal with the existinglight switches.
When the occupant leaves the room and removes the Key Card the Key Card Switch sends the “Room Unoccupied” message and the main lighting circuit isdisabled so turning off all lights. A switch off time delay can be set up in the lighting actuator giving occupants the chance to leave the room before all lightsare disabled.
4 Estimated Costs and SavingsAt this stage we are only able to provide budget costs for the solutions discussed. We can then help hotel management to more clearly define their exactrequirements.
Estimated savings very much depend on the thermal characteristics and heat gains of the building. As no figures on actual measured heat gains areavailable these have therefore had to be estimated.
Building Evolution Ltd Claremont Hotel Energy Report July 2014
18
Heat gains have been estimated to be about 7.5 degrees. This is based on the fact that room temperatures have been measured as being quite high ( figuresfrom Kevin at ISO IOM give an average of 26 degrees with outdoor temperatures of 9 degree). Some of this will be attributed to solar gain but my opinion isthat much of this will be due to the fact that as a hotel which is operating 24/7 the building will produce a relatively constant source of heat. Also, thereseems to be a strong possibility that domestic hot water pipes that run through the hotel may not be particularly well insulated, therefore providing afurther significant source of heat.
From information provided by Epsilon Consultants it would appear that the heating is only switched on for 9 hours a day. If this is kept like this all year thenthis is would already be providing significant savings. However, it is understood that these time-clock settings are not kept all year round and are adjustedto take into account sudden guest requirements or colder weather.
Energy savings are worked out using daily Degree Day data for 36 months from 1st July 2011 to 16 July 2014 provided by the weather station at Ronaldsway.
Degree Days are widely used in the energy industry for calculations relating to the effect of outside air temperature on building energy consumption.
"Heating degree days", or "HDD", are a measure of how much (in degrees), and for how long (in days), outside air temperature was lower than a specific"base temperature" (or "balance point"). They are used for calculations relating to the energy consumption required to heat buildings.
"Cooling degree days", or "CDD", are a measure of how much (in degrees), and for how long (in days), outside air temperature was higher than a specificbase temperature. They are used for calculations relating to the energy consumption required to cool buildings.
For further introduction and explanation of Degree Days please see www.degreedays.net.
Heating Degree Days for the present situation with heating of radiators in all rooms controlled by the time-clock are:
Present Situation Rooms Degree DaysDegree Days with Radiators on Time-clock 56 189151
4.1 Possible management plan to add standard air-conditioning into 18 rooms – No Keycard.In order to estimate savings it has been assumed that the hotel management will go ahead with a plan to install air-conditioning in 18 guest rooms. This willleave 38 rooms on the present heating time-clock. Energy saving have therefore been calculated by looking at energy usage with 38 rooms staying as theyare now, i.e. With radiators on a time-clock, and 18 rooms with air-conditioning that is left running permanently (i.e. no occupancy detection withKeycard). The time-clock settings used in the model are shown in Epsilon Consultant’s report.
Building Evolution Ltd Claremont Hotel Energy Report July 2014

Degree Days estimated for this option are:
Option 1 – Air-conditioning installed in 18 rooms, remaining rooms keepradiators on a time-clock normal, AC on permanently with heating setpointof 21 degrees and cooling setpoint of 23 Degrees
Rooms Degree DaysRooms with RADs only on Time-clock 38 128353Rooms with AC On All Time Heating 18 71690Rooms with AC On All Time Cooling 18 2999
Total 203042
Note: Degree days (energy used) has increased by about 7% by installing air-conditioning as energy is also required for cooling.
4.2 Standalone Keycard Solution for Rooms with Radiators and Air-conditioning.4.2.1 Option 2The following solution is a standalone Keycard system controlling air-conditioning in 18 rooms. Turning Air-conditioning on/off only. The remaining 38rooms keep their radiators on the existing time-clock.
Option 2 - Air-conditioning installed in 18 rooms but with Key-card systemfor occupancy detection. Remaining 38 rooms keep radiators on a time-clock.

It is estimated that there will be an annual energy saving of around 14% when compared to the present situation.
It is estimated that a 20% energy saving can be made compared to Option 1. Notice that using a keycard system with the air-conditioning will reduce energyused by an estimated 53%.
The budget cost for this control solution is £10,500
Due to the fact that we do not know what proportion of the gas bills are spent on heating rooms we are unable to provide an estimated payback period.Epsilon Consultants will however hopefully be able to provide this figure.
4.2.2 Option 3The following option is a standalone Keycard system controlling air-conditioning in 18 rooms, turning air-conditioning on/off only, and wireless controlscontrolling radiators in 38 rooms with a comfort and a standby setpoint of 21 and 19 degrees respectively.
Option 3. Air-conditioning installed in 18 rooms and radiator wirelessheating controls installed in 38 rooms. Keycard system turns AC on/off andalters radiators between two setpoints.

4.3 Networked Rooms – Building Management Solution4.3.1 Option 4The following option provides a BMS system to provide control of heating and cooling in all rooms. A combination of a Keycard and Micros Fedelio changingthe room between Comfort, Standby and Economy set points. Rooms are also put to the lower setpoint by the BMS for 6 hours at night e.g. between 11pmand 5am.
Option 4: All rooms networked onto a BMS system for heating and coolingcontrol.

Due to the fact that we do not know what proportion of the gas bills are spent on heating rooms we are unable to provide an estimated payback period.Epsilon Consultants will however hopefully be able to provide this figure.
The above figure includes the cost of the Micros Fidelio Interface. Micros have said that the cost of the interface is £1515.30 and there is also a monthlysupport cost of £30.30 per month (not included), they will also need a day’s remote Interface time to setup and configure the Interface. This should becharged to the hotel direct from Micros and should be confirmed by the hotel management.
4.3.2 Additional Wireless PossibilitiesWireless technology offer possibilities to extend the system within each room to provide even greater control. For example, wireless window contacts canautomatically set back the heating or air-conditioning if a window is left open and then restore the room to its proper setting when the window is closed. AKey Card switch could also enable and disable the power to the TV or other electrical devices so preventing them being left on standby or for safetypurposes.
Building Evolution Ltd Claremont Hotel Energy Report July 2014
22
Wireless blind actuators could automatically cloze window blinds to provide shading when the room is unoccupied so preventing over heating from solargain. This means that any air-conditioning does not use as much energy trying to maintain a cooler room. Blinds could be opened automatically when theKey Card is inserted in to the Key Card Switch.
5 Basement Function Rooms and Guest WCs and Corridors.5.1 Lighting5.1.1 SituationAt present certain lights have already been replaced with LEDs which will have helped reduce energy costs.
In the function reception area (as you come down the stairs from the hotel reception) lights are controlled manually from switches located in the storeroom under the stairs. Switches here also control the lights to the Guest WCs and the WC corridor off the reception area.
Most lights in this reception area are turned on in the morning and left on all day till possibly around 11 or 12 pm at night. It is presumed that the WC andWC corridor lights are all turned on for the same period.
Lights in the Guest WCs and the Guest corridor at the far end of the building appear to be controlled only by emergency key switches. These lights are lefton 24 hours a day 365 days a year. WC extractor fans are connected to the light circuits so these are also running 24/7.
In the function rooms, lights are controlled by a mixture of a Rako Lighting System that provide scene control for some of the lights and standard wiredswitches and dimmers to control others.
All trough lighting in the function rooms are T5 fluorescents.
5.1.2 ProblemsLights being left on when the rooms are not being utilized results in higher than necessary energy cost.
Function room celling pendent lights have been replaced with LED bulbs, however, because these are controlled by the original standard dimmers, whichare unsuitable for dimming an LED bulb, they are difficult to adjust and have a tendency to flicker. Although not directly an energy issue it does indicate theproblems associated with just trying to replace standard bulbs with LED.
It is noted that the existing Rako system does not control all the lights in the function rooms as the ceiling pendants in two of the function rooms arecontrolled by two standard rotary dimmer switches. However, both of these switches are in the first function room which means if the function roompartition is closed then the pendent lights in Function Room 2 are sometimes turned on accidently and no-one would know the lights have been turned onbecause you cannot see through to this room from the far end. It must also be inconvenient at times to have a dimmer switch in a separate area in whichthe lights it controls are located.
Building Evolution Ltd Claremont Hotel Energy Report July 2014
23
The fluorescent trough lighting cannot be replaced with more energy efficient LED strip lighting as the existing Rako System cannot dim LED strip lighting.
5.1.3 Possible SolutionsChanging florescent trough lights in the function reception for LED strip lights. These are not dimmed.
In the far guest WC corridor the dual compact florescent lighting could be replaced with equivalent LED.
Put occupancy sensors into all public WCs.
Putting in a replacement control system that controls the Function Reception and both main Function Rooms along with public corridors. This could providethe following functions.
Allow lighting in Reception and Function rooms to be kept turned off. Then have occupancy detection turn on only minimal lighting for people justpassing through or staying in the room for only a brief period.
On/Off or scene control for function rooms including dimming of any new trough LED strip lighting. When no function room is being used put the control of all WC lights and public corridors onto movement and occupancy sensors but provide
automatic linking and therefore holding on of this lighting when any function/ reception rooms are being used. Control of system through IPad, web browser, smartphone within the function rooms. The same control system could also automatically enable and disable the air-conditioning by linking with the control of the main function room
lights. A possibility to interface this control system with the main BMS so that control of the function rooms can be done through the graphical user
interface of the BMS.
5.1.4 Estimation of Present Lighting Energy CostsAnalysis and calculation has been carried out of all existing lights and the savings made possible by replacing them with LED lighting. An estimation of howoften lights are presently are turned on is also considered. Further to this by adding occupancy sensors in these areas and providing an estimated figure forhow long lights will be on with occupancy gives another figure for expected energy saving.

In addition to the above, due to the fact that extractor fans in the WCs will be linked to the lighting means that further energy will be saved by theoccupancy sensors. This saving is estimated at around £130 per year.
This brings total annual savings for function areas to an estimated £2093.
Budget costs for replacing lights with LED and providing a new control system for lighting is: £12,500
Estimated payback period is 6 years based on a constant electricity price of 13.53 pence per kWh over that period.
6 Basement Staff AreasMost other areas of the basement staff areas were also surveyed and existing light types and their wattage noted. (Some store rooms could not beaccessed)
6.1 SituationDuring the original hotel conversion from a number of boarding houses there was no major rewiring of lighting circuits to take into account new room andcorridor layouts. The result is that a number of separate rooms and corridors share the same switched lighting circuit. So for example if a corridor light is onthen so are the lights in one or more store rooms.
Building Evolution Ltd Claremont Hotel Energy Report July 2014
25
Most lighting in these staff areas are fluorescent T8 fittings.
6.2 ProblemsSome lights in staff areas are appear to be left switched on 24/7 and 365 days a year. Other lights are switched off by a member of staff at night, howeverthere are periods in the day during working hours when no staff are present in a room but lights are left on.
Some switches for a corridor light are in a locked store room meaning that it is difficult to turn these lights off.
6.3 Possible solutionsReplace or adapt all lighting to LED.
Control lights in all areas with movement and occupancy sensors.
6.4 Estimation of Present Lighting Energy CostsAnalysis and calculation has been carried out of all existing lights and the savings made possible by replacing them with LED lighting. An estimation of howoften lights are presently are turned on is also considered.

3 important features give Load Tracker C
HP the advantage w
hen it comes to delivering
sustained operation: •
A g
enerato
r capab

utp
ut to track site d
eman
d. M
odulation from
the XRG
I 20G LoadTracker C
HP unit is betw
een 10.0 - 20.0 kW(e). W
ith m
ultiple installations, modulation is over a m
uch wider range, as the load is shared
automatically betw
een units. This means that LoadTracker C
HP can expect to
remain in operation during periods of low
demand (w
hen non-modulating units
would be forced to trip out).
• A
therm
al storag
e vessel to absorb
the m
ismatch
es betw
een site th
ermal
dem
and
/C
HP
therm
al ou
tpu
t. LoadTracker CH
P vessels are provided with a
dynamic control system
which m
aximises C
HP running tim
e. By accurate
managem
ent of vessel contents, the full thermal storage potential is used to cover
site peak loads. This prevents unnecessary operation by the less efficient back-up boilers.
• Efficien
t captu
re of process h
eat. This is achieved by a heat distributor, able to m
aintain 80°C flow
regardless of system return tem
peratures. A com
prehensive development program
me by EC
Power has delivered further benefits:
• A
n ad
apted
version of th
e rug
ged
Toyota gas en
gin
e, go
od for 6
,00
0 h
ours
betw
een services. This plays a m
ajor part in keeping maintenance costs low
. The engine can be reckoned to provide 50,000 running hours betw
een overhauls. •
Low n
oise emission
. At only 49 dB
(A) at 1m
(about the same as office
conversation), LoadTracker CH
P is a good choice for applications involving sensitivity to noise.
• A
control p
anel to b
ring
the C
HP
on lin
e and
out of service au
tomatically.
There is no interaction required from the B
MS. Local visual display is available, w
ith data on plant operation also available rem
otely via modem
. Please rem
ember, there are several different w
ays of integrating LoadTracker CH
P within
plant room pipe w
ork. As part of this quote PD
F, there is a suggested layout which should
optimise the running hours to be expected from
the CH
P, based on the information of the
project which w
e have to date. How
ever, if a more appropriate m
ethod of connection becom
es apparent during further project discussions, we w
ould be happy to discuss alternatives. For each individual project, S
AV S
ystems offer to undertake an assessm
ent of CH
P potential. This exercise does not take long and is carried out w
ithout charge. Given basic
information about site therm
al and electrical loads, SAV S
ystems w
ill produce a brief report outlining the expected C
O2 reduction, cost savings and the expected share of therm
al load to be taken by LoadTracker C
HP. It w
ill also provide recomm
endations for thermal storage
vessel volume.
When the tim
e comes to install, S
AV S
ystems can count on the services of an excellent
installation partner, Aston C
ord Ltd. Although a prelim
inary estimate for installation has
been provided with this quote, A
ston Cord w
ould be happy to attend site to conduct a prelim
inary survey. This would enable them
to firm up on a m
ore realistic estimate, and
also submit a detailed sum
mary of issues to be anticipated w
hen site activities comm
ence. There is nothing like seeing LoadTracker C
HP for real. If you w
ould be interested in a site visit to an existing installation, w
e have numerous sites around the U
K to w
hich this could readily be arranged. You only have to let us know
!

ed to operate (supplied by SAV S
ystems or any other party), w
ritten agreem
ent to this must first be secured from
the local District N
etwork O
perator (or DN
O, ie,
the electricity supply company). This condition is laid dow
n by Engineering Recom
mendation
G59 (2010). W
ithout such agreement, the D
NO
may im
pose a generation cessation order. 6.
The relevant Application Form
s to the DN
O can be filled out and subm
itted either by the site operator or by a separate party on behalf of the site operator (the consultant, the contractor or by S
AV S
ystems). If the purchasing contractor agrees w
ith the eventual client that SAV
System
s should carry out the Application process, this should be confirm
ed at the time of the
order for equipment supply. This m
eans that an early start can be made w
ith the Application
process, which can take 3 - 6 m

7. Should
SAV

it is
recomm
ended that provision be made by the purchasing contractor for the one-off charge
which m
ay be imposed by the D

3 important features give Load Tracker C
HP the advantage w
hen it comes to delivering
sustained operation: •

enerato
r capab

eman
d. M
odulation from
the XRG
I 20G LoadTracker C
HP unit is betw
een 10.0 - 20.0 kW(e). W
ith m
ultiple installations, modulation is over a m
uch wider range, as the load is shared
automatically betw
een units. This means that LoadTracker C
HP can expect to
remain in operation during periods of low
demand (w
hen non-modulating units
would be forced to trip out).
• A
therm
al storag
e vessel to absorb
the m
ismatch
es betw
een site th
ermal
dem
and
/C
HP
therm
al ou
tpu
t. LoadTracker CH
P vessels are provided with a
dynamic control system
which m
aximises C
HP running tim
e. By accurate
managem
ent of vessel contents, the full thermal storage potential is used to cover
site peak loads. This prevents unnecessary operation by the less efficient back-up boilers.
• Efficien
t captu
re of process h
eat. This is achieved by a heat distributor, able to m
aintain 80°C flow
regardless of system return tem
peratures. A com
prehensive development program
me by EC
Power has delivered further benefits:
• A

apted
version of th
e rug
ged
Toyota gas en
gin
e, go
od for 6
,00
0 h
ours
betw
een services. This plays a m
ajor part in keeping maintenance costs low
. The engine can be reckoned to provide 50,000 running hours betw
een overhauls. •
Low n
oise emission
. At only 49 dB
(A) at 1m
(about the same as office
conversation), LoadTracker CH
P is a good choice for applications involving sensitivity to noise.
• A
control p
anel to b
ring
the C
HP
on lin
e and
out of service au
tomatically.
There is no interaction required from the B
MS. Local visual display is available, w
ith data on plant operation also available rem
otely via modem
. Please rem
ember, there are several different w
ays of integrating LoadTracker CH
P within
plant room pipe w
ork. As part of this quote PD
F, there is a suggested layout which should
optimise the running hours to be expected from
the CH
P, based on the information of the
project which w
e have to date. How
ever, if a more appropriate m
ethod of connection becom
es apparent during further project discussions, we w
ould be happy to discuss alternatives. For each individual project, S
AV S
ystems offer to undertake an assessm
ent of CH
P potential. This exercise does not take long and is carried out w
ithout charge. Given basic
information about site therm
al and electrical loads, SAV S
ystems w
ill produce a brief report outlining the expected C
O2 reduction, cost savings and the expected share of therm
al load to be taken by LoadTracker C
HP. It w
ill also provide recomm
endations for thermal storage
vessel volume.
When the tim
e comes to install, S
AV S
ystems can count on the services of an excellent
installation partner, Aston C
ord Ltd. Although a prelim
inary estimate for installation has
been provided with this quote, A
ston Cord w
ould be happy to attend site to conduct a prelim
inary survey. This would enable them
to firm up on a m
ore realistic estimate, and
also submit a detailed sum
mary of issues to be anticipated w
hen site activities comm
ence. There is nothing like seeing LoadTracker C
HP for real. If you w
ould be interested in a site visit to an existing installation, w
e have numerous sites around the U
K to w
hich this could readily be arranged. You only have to let us know
!

The relevant Application Form
s to the DN
O can be filled out and subm
itted either by the site operator or by a separate party on behalf of the site operator (the consultant, the contractor or by S
AV S
ystems). If the purchasing contractor agrees w
ith the eventual client that SAV
System
s should carry out the Application process, this should be confirm

7. Should
