First Canadian Place (FCP) is an iconic landmark in Toronto’s Financial District. At 72 storeys, it has been Canada’s tallest commercial building since 1975. With over 2.3 million square feet of office space and 232 retail locations, it requires a significant amount of energy to keep business humming.

Brookfield Properties manages FCP and has received industry recognition for improving the building’s energy performance, focusing on key elements of human and environmental health and controlling costs. The building is targeting Gold level LEED certification by Q4 of 2012.

Fernando Dias, the Senior Operations Manager for the building, is directly responsible for numerous energy-efficiency projects, including the most recent upgrades to the air handling units, the heating and cooling pumps and lighting.

These three projects qualified for a total incentive of $669,198.20.

Three ambitious retrofit projects deliver big savings to First Canadian Place

aBOvE Fernando Dias, Senior Operations Manager

“My suggestion is to get toronto Hydro involved right from the beginning. their staff will assist you with incentive programs and help you find even more savings.”

Fernando Dias is very experienced at managing energy-efficiency programs.

“In this building we’ve been working with incentive programs for the past four years. A recent project was to convert all of our motors and pumps to variable frequency drives (VFDs). That went very smoothly.”

In one project, 16 air handling units serving the building’s main heating and cooling system were retrofitted with VFDs.

By upgrading the supply and return fans with VFDs, demand was reduced by 208.4 kW and total energy use went down by 727,982 kWh/yr. The incentive for this project was $166,720.

vFDs on heating and cooling pumps drive down power usage

There are 27 centrifugal pumps that serve the building’s main heating and cooling system. All were retrofitted with

variable frequency drives. Demand went down by 167 kW and total energy usage was reduced by 4,898,082 kWh/yr. This project qualified for an incentive of $489,808.20.

Dias notes, “The VFD program basically took two years from the start of the application to when we received our incentive cheque.”

Dias goes on to say, “We had some comfort issues in the building before, and we’ve noticed that calls have started to drop. We’ve been able to give tenants a better comfort zone.”

Motion sensors plus t5 fixtures maximize savings

Lighting on the 60th floor was updated, with 350 T5s replacing 500 T8 units. Also, both the 60th and 59th floors were outfitted with 138 motion sensors to further reduce electricity use. The total energy savings are 138,506 kWh/yr with demand savings of 12 KW. Annual electricity savings are $15,300 and the project qualified for an incentive of $12,670.

In another lighting project in the lobby, metal halide and fluorescent bulbs were converted to 21-watt and 9-watt LEDs. Dias said, “When people walk in they think that we’ve increased our lighting. In reality lighting costs have gone down, but we’ve increased our illumination.”

“In the last 4 years we dropped demand from 17.5 MW to roughly 13 MW. aside from the considerable savings, we’ve also improved tenant comfort.”

Factor incentives into the return on investment (ROI)

MLSE met with Toronto Hydro for assistance in maximizing their investment and ROI. Toronto Hydro assisted MLSE in making choices and showed how incentive programs could support energy efficiency goals. MLSE included the incentive plan in a proposal to senior management and also worked very closely with its contractor, Mechanical Trade Industries (MTI). MTI completed a comprehensive 93-page report that factored in everything from energy use to waste management.

think outside the rink to find the biggest savings

Compared to other types of facilities, Air Canada Centre is a very complex building with diverse lighting requirements. In assessing the opportunities to reduce energy, MLSE’s Building Operations team found potential cost savings in replacing the MR16 and T-8 lamps used. As a result, lighting changes were made in the food and beverage concessions, souvenir shops, office areas, private suites, parking garages, corridors and, of course,

the team dressing rooms. MLSE also found numerous opportunities to reduce energy with occupancy sensors in concourses and office areas.

Even relatively new buildings present savings opportunities

Air Canada Centre was completed in 1999, and since then, there have been many advances in energy efficiency that can make a substantial difference to electricity consumption.

MLSE believes that it’s also key to have up-to-date building drawings. If you’re not confident that they are current, put the onus on the contractor to verify services and update as-built drawings as part of the project.

Get management buy-in and partner expertise early

MLSE found that two key factors were critical to achieve success in meeting energy goals:

1. Senior management leadership and complete buy-in from all divisions, with an understanding that energy efficiency is the new normal.

2. Facilities managers need to approach their utilities and connect with contractors early in the process. This way they can bring their experience to bear on your project as a significant added value.

“Build a solid team. Use your utilities and contractors as resources. That’s what worked for us.”

Reduce Electricity Costs with Demand Control Ventilation

Canadian Tire participated in the saveonenergy RETROFIT PROGRAM to implement energy saving measures across 129 stores in Ontario. As one of Canada’s most trusted brands with 490 stores from coast to coast, the proud Canadian company provides innovative products and services that meet customer needs without compromising the environment.

“Canadian Tire has been committed to sustainable operations for a very long time,” says Rob Simpson, Manager of Design and Sustainability at Canadian Tire. “We were one of the first Canadian companies to include sustainability metrics as part of our quarterly and annual reporting. We’ve implemented a number of energy efficiency initiatives in our existing stores—from lighting retrofits and building automation to the way we heat and cool our buildings. So when we heard about how the saveonenergy program could support projects like Demand Control Ventilation to reduce energy consumption, we were eager to learn more.”

WhAT IS DEMAnD COnTROl vEnTIlATIOn?Traditionally, heating and cooling systems have been designed to meet air quality standards by using general guidelines for minimum air ventilation rates provided by aSHRaE (american Society of Heating, Refrigerating and air Conditioning Engineers). The traditional approach maintains a constant outdoor air volume based on the size and design occupancy of the space. outdoor air usually needs to be conditioned. This method can often result in a significant waste of energy and money during times when fewer people are in the building.

a Demand Control Ventilation (DCV) system uses carbon dioxide (Co2) sensors to monitor the levels of carbon dioxide in the air on a continual basis. Changes in a building’s occupancy will affect the level of carbon dioxide in the space. The monitors detect this and increase the supply of outdoor air. When fewer people are in the building, the controller reduces the volume of ventilation air to reduce energy consumption while maintaining the indoor air quality.

“From the saveonenergy RETROFIT PROGRAM incentive application submission through to project implementation, we helped streamline the process and meet the client’s tight construction deadlines,” he adds.

The project was a result of Enbridge gas Distribution, the ontario Power authority, Toronto Hydro and Canadian Tire’s business partner, inviro Engineering Systems, working together to introduce the benefits of installing DCV. “The DCV campaign, which provided an increased natural gas incentive when combined with the saveonenergy RETROFIT PROGRAM incentive, made this project financially appealing,” says John Tideman, Senior Manager, Commercial DSM Sales and Marketing at Enbridge.

Canadian Tire and its partners were able to complete the retrofit within a short four month period. “Enbridge was also successful in completing the necessary audit to issue the natural gas incentive payments for all locations by the end of the calendar year,” Tideman says.

SEEInG ThE SAvInGS The savings estimated across the 129 stores were based on a number of factors, and so far the program is meeting expectations. annual energy savings are expected to include 2.5 million kWh, 2 million m3 of natural gas, over 1,000 kW of Demand Savings, and over 5,000 tonnes of Co2.

InCEnTIvE bEnEFITS Due to the ease of the saveonenergy RETROFIT PROGRAM and the resulting benefits of this project, Canadian Tire isn’t stop-ping at DCVs. “We are always looking at the latest tech nologies, including advances in lighting technology and opportunities to improve our efficiency from a heating and cooling perspective,” says Simpson. “We expect many of these technologies to be integral to future energy saving projects. We would eagerly participate in the saveonenergy programs in the future.”

Condo board shines with big savings in lighting retrofit

saveoNenergy OM

For BUsiNess

Lighting was an obvious place to look for savings

With 35% of the operating budget devoted to electricity costs, it was clear that the metal halide and T-12 lighting systems in the common area of the two buildings needed updating. Metal halide bulbs are also an environmental concern, containing more mercury than fluorescent bulbs.

With the goal of maintaining current light levels, increasing security, safety and a long term reduction in operating costs and energy consumption, The Masters collaborated with their supplier and contractor Lighting Solutions and leveraged incentives to achieve this goal.

a pre-project audit provided reassurance

A pre-project audit was conducted in order to determine the level of reductions that could be achieved in both kilowatt load and kilowatt-hours without compromising perceived light levels, safety and security. As a result of this study, a decision was made to undertake a full retrofit of the lighting

system with the assistance of energy incentives which significantly improved the rate of return on investment.

The existing metal halide lighting system in the garage, with a total load of 50.6 kW, was removed and replaced with a high efficiency T-8 lighting system. This retrofit resulted in a 72% reduction in load representing a yearly reduction of 291,130 kilowatt-hours.

project surpassed initial savings goals

The retrofit also included an upgrade of the lighting system in the stairwells, fitness area, meeting rooms and clubhouse, resulting in a yearly reduction of 126,722 kWh. The total electricity savings for the whole project is equivalent to taking 80 cars off the road.

With the completion of the retrofit projects, The Masters was able to surpass their goal of $40,000 in annual cost savings per year.

incentives reduced payback period

“As managers of condominiums, we are working within a non-profit environment. The owners’ maintenance fees are the

only source of budget income. Our ongoing mandate is to find ways to reduce operating costs,” said Nena Gajic, Property Manager. “We knew a lighting retrofit proposal with less than two year payback, reduction in future operating costs and a generous incentive to boot would be a welcome winner!”

For Savoy Plaza Apartments, investing in energy improvements pays regular dividends

aBOvE Introducing motion sensors to Savoy Plaza’s hallways delivered approximately 78% reduction in energy demand.

Built in the 1950s, the Savoy Plaza is a premium rental property located in Toronto’s Old Forest Hill Village.

Simple changes yield sustainable savings

Mitchell Chang contacted MultiLogic Energy Solutions Inc., which

upgrades for multi-residential complexes, to conduct an energy audit and see where savings were possible. MultiLogic produced a report detailing proposed improvements and potential savings, identifying that installing more

stairwells and hallways could deliver demand and energy reductions of about 78%. Additional energy savings, 40% in stairwells, 65% in hallways and 90% in the parking garage, were possible by introducing motion sensors.

From an economic perspective, the proposal made good sense. Energy demand and costs could be substantially reduced, lowering Savoy Plaza’s energy costs by approximately $2,556.43 annually. The incentives available from the saveONenergy programs offered through Toronto Hydro provided motivation to act. And with a short payback period estimated at just under two years and a return on

investment of 56%, this project has proven to be a rewarding use of capital for the property owner.

Incentives shorten project payback

MultiLogic sourced all products, arranged for the installation of all equipment and worked with the property owner and Toronto Hydro to apply for the available incentives. Savoy Plaza received $4,137.38 in incentives, reducing the project cost by nearly one half and the payback period to approximately 1.79 years.

Tenants appreciate energy efficiencies

Providing tenants with education about

lighting and the use of motion sensors was a key component of the project’s success. “Our tenants are really pleased with the new lighting and appreciate that we are taking concrete steps to make Savoy Plaza more

Not only does this energy effi cient lighting retrofi t reduce energy use, the savings in annual operating costs provide ready cash for other building improvements.

With an annual bill of more than $100 million for water, heat and electricity in its 2,215 buildings, Toronto Community Housing Corporation (TCHC) has plenty of motivation to fi nd effi ciencies. Dollars saved on annual operating costs can be put back into capital improvements, ultimately delivering a better quality of life for TCHC’s 164,000 tenants. TCHC’s Building Tune-up program is a multi-year plan for reducing operating costs through more effi cient use of water, electricity and gas in both tenant suites and building common areas. If the lighting retrofi ts completed in 2011 are any indication, TCHC can expect to see considerable cost savings.

Simple solution with fast payback

According to Phillip Jeung, Director, Smart Buildings and Energy Management at TCHC, a lighting retrofi t is a low-cost, simple way for multi-residential buildings to realize substantial energy savings. In this case, TCHC received $65,028 in incentives available from the saveONenergy RETROFIT PROGRAM offered through Toronto Hydro. With these retrofi ts, TCHC was able to achieve annual electricity savings of 2,569,408 kWh, equivalent to powering approximately 214 homes.

Help for getting incentives

From now through 2014, incentives of up to 50% of project costs are available for qualifying social housing projects. Toronto Hydro worked with TCHC to provide support for building the business case and applying for saveONenergy incentives. Mike Mulqueen, Toronto Hydro’s CDM Program Management Consultant for the Social Housing sector, explains, “Worksheet templates are available for a wide variety of electricity conservation initiatives, making it easy to quantify a project’s savings and apply for incentives online.”

Keeping project costs down

Another important factor in building a sound business case and shortening the payback period is keeping project costs low. TCHC used Housing Services Inc. (hsi) as their Project Manager and General Contractor under a unit price/fi xed fee agreement, providing cost reductions and signifi cantly increasing TCHC’s return on investment. hsi Project Manager Pamela De Melo, Design, Build and Engineering Services points out that, “With hsi’s role and approach, we were able to provide additional technical expertise and energy saving options to help reduce overall project costs.” As an added bonus, hsi is an approved Toronto Hydro Applicant Representative, and continues to assist TCHC with pursuing opportunities under the RETROFIT PROGRAM.

Encouraging results

Following the successful completion of lighting retrofi ts in 15 of its buildings in 2011, TCHC is undertaking similar projects in 74 buildings in 2012 and 30 properties in both 2013 and 2014. For additional operational cost savings to fund capital improvements, TCHC is

Fortunately, ongoing advances in server virtualization technology are dramatically improving server speed and capacity. Newer servers operate more efficiently resulting in significant reduction in hardware requirements and electricity consumption.

The Scarborough Hospital (TSH) is Canada’s largest urban community hospital, serving a community of almost one million people (roughly a third of the GTA). A leader in research, teaching and learning, TSH operates with more than 3,400 staff, 700 physicians and 600 volunteers.

The servers are virtual, but the savings are real for the Scarborough Hospital

The move to server virtualization produces multiple benefits

Rather than add more servers to keep up with growth, data centres are now taking advantage of the efficiencies offered by server virtualization.

“Virtualization” is a software technology that allows you to run multiple virtual machines on a single physical machine, sharing resources of that single computer across multiple environments.

“We now have the equivalent of 62 servers running on four virtual servers. However, our virtual servers actually have the capability of running 95 servers, so we already have the capacity for growth,” says Kelly. TSH was also able to identify and consolidate an additional 17 servers into the remaining existing physical servers.

Power requirements are down substantially and are now constantly monitored

Power consumption was an important criteria evaluated in the procurement process and was clearly a differentiating consideration.

Kelly also implemented new control systems, developed by Integrated Monitoring Solutions (IMS), to provide precise real-time power usage, environmental conditions and alarm reporting.

Fewer servers require less air conditioning

Aside from the reduced electricity demand for the servers, Kelly and his team will also benefit from lower air conditioning loads. As a result, they were able to utilize smaller more efficient cooling equipment and eliminate up to 20 tons of cooling capacity/load.

Working with Toronto hydro was “seamless”

The entire project was completed in less than four months. Michael Pardal, from Toronto Hydro, met with Kelly at the beginning of the project and then checked in regularly. Kelly specifically appreciated the help in guiding TSH through the application process and the assistance with the incentive paperwork. Kelly sums up the experience as “very professional, very positive and Toronto Hydro’s support was seamless from beginning to end.”

In addition to receiving a significant financial incentive from Toronto Hydro upon project completion, TSH is looking forward to the annual savings in electricity and strong ROI.

“We have replaced 41 servers with 4 virtual ones, and each new server is more energy efficient than any one of the older ones.”

Innovative chiller technology delivers immediate results

With current energy prices trending higher and the possibility of additional increases in future, Humber College must manage its resources carefully to ensure that facilities are operating as efficiently and environmentally responsible as possible.

Today, there is increased pressure for Humber College to invest in infrastructure upgrades that will reduce its carbon footprint with lower greenhouse gas emissions.

With the help of their subcontractor, S.A. Armstrong Ltd., Humber College sought to reduce the carbon footprint of its North Campus and minimize energy operating costs through an innovative energy-efficiency upgrade.

$127,240 incentive lets Humber College do more

Humber College developed a $2.88 million program to replace the 35-year old chiller system at the North Campus with an innovative system called the Hartman Loop. They took advantage of an energy saving incentive of $127,240, which enabled Humber College to do more with their budget.

The Hartman Loop system uses three new 550-ton chillers with integrated plant control technology that is 50 per cent more efficient than Humber College’s two former chillers that ran on harmful chlorofluorocarbons (CFCs).

Annual electricity consumption down by 449,937 kWh

The Hartman Loop chiller system resulted in a reduction in annual electricity consumption at Humber College’s North Campus – 449,937 kWh. The program is also expected to trim utility bills by $44,994 per year. The $127,240 in financial incentives allowed Humber College to reach a new standard in fiscal and environmental responsibility.

“The existing chiller system was a drain on the environment and our facilities were in serious need of an upgrade,” said Carol Anderson, Director of Facilities. “By replacing the two existing chiller units with the Hartman Loop chiller system, we will reduce our environmental footprint by 443 tonnes of CO2 annually – that’s the equivalent of taking 100 cars off the road, or taking 150 homes off the grid.”

A few years ago, as part of the Transmission Operations Optimizer project and Water Supply’s energy management plan as well as the F.J. Horgan Plant expansion, Toronto Water conducted a detailed review and evaluation of pump flow, pressure and electricity use data to identify energy-saving opportunities in their operations.

As a result, eight pumps were replaced and one was optimized at the Parkdale Pumping Station, the William Johnston Pumping Station and the F.J. Horgan Water Treatment Plant.

Toronto Water pumps up savings with motor retrofits

ABOVE: Chris Tyrrell, Vice-President, Customer Care and Chief Conservation Officer, Toronto Hydro presents the incentive cheque for the Parkdale Station project for $681,164 to Larry Korson, Director, Water Treatment & Supply.

“Becoming more energy efficient is paying off for Toronto Water and aligns with our division’s vision to produce water in an environmentally friendly and fiscally responsible manner,” said Larry Korson. “Submitting these projects to Toronto Hydro helped the City improve project payback.”

Today, Toronto Water is actively pursuing further energy reductions. Approximately 20 additional projects have been scoped and submitted for incentive funding.

it pays to evaluate existing technology for energy efficiency

While the saying might be, “if it isn’t broken, don’t fix it”, that’s often a false economy. Today, many companies and organizations are operating with old equipment that may still be working, but is very inefficient and costly to operate.

In some cases, it’s possible to optimize existing equipment through the addition of new controllers or other modifications. At other times, replacement is the best answer to save energy and avoid the inevitable repairs and maintenance required by aging equipment.

As Toronto Water learned, it pays dividends to do an efficiency review and then replace or upgrade where it makes financial sense, especially when incentives are available to shorten payback periods.

“once we engaged our employees to help us identify energy-saving opportunities, we soon had a long list of potential projects. We have prioritized them and are pursuing many of the improvements now.”
