Executive Summary

The University Research Building (URB) is being constructed to house three collaborative

research labs: the Extreme Materials Institute, the Individualized Health Initiative, and the Systems

Institute. Each of these research programs pulls expertise from multiple departments within the

university, and the URB will provide laboratory and office space to foster communication and

collaboration. The building will also be home to the university’s Computer Science department.

This report contains three main sections: electrical systems criteria and scope of work, an

overview of the electrical systems as currently designed, and an evaluation of the designed systems vs.

the initial criteria.

Part I – Electrical Systems Criteria and Scope of Work

Preliminary Electrical Load Calculation

General Lighting Loads by Occupancy – NEC Table 220.12

Office Buildings: 3.5 VA/ft2 x 61858 ft2 = 216503 VA

Halls, Corridors, Closets, Stairways: 0.5 VA/ft2 x 8258 ft2 = 4129 VA

Storage Spaces: 0.25 VA/ ft2 x 168 ft2 = 42 VA

Total Anticipated Lighting Load = 220.7 kVA

Receptacle Outlets – NEC Article 220.14(K)

1 VA/ ft2 x 70284 ft2 = 70.3 kVA

HVAC Systems – R.S. Means Electrical Cost Data 2013 – Table D3020

15.6W/ft2 x 70384 ft2 = 1,100 KW

Identify Power Company Serving Location

Baltimore Gas and Electric (BGE)

Preliminary Rate Schedule Selection

The building is fed from a campus power distribution loop. The applicable rate schedule is likely

Schedule P – Primary, at a service voltage of 13.2 kV.

Voltages

Lighting: primarily 277V, with some 120V for LED wall-grazing fixtures and undercabinet lighting

Receptacles: 120V

HVAC: 480V 3-phase

Servers: 120/208V Panels

6

Emergency Power Requirements – Based on IBC

Group B (Business) Occupancy

Emergency Power

- Exit Signs

- Means of Egress Illumination

Standby Power

- Smoke control systems

- Elevators

Fuel Source: Diesel

The sister building to the URB has a 250kW generator at 277/280V. The emergency and standby

load requirements will likely be similar for the URB, so a similar generator may be expected.

Special Occupancy Requirements

There are not any anticipated special occupancy requirements per Chapter 5 of the NEC. While it

is a university building, the URB does not feature any large lecture halls that would be

considered assembly spaces.

Anticipated Special Equipment

NEC – Chapter 6

605 – Office Furnishings

620 – Elevators

640 – Audio Systems

645 – Information Technology Equipment

647 – Sensitive Electronic Equipment

690 – Solar Photovoltaic (PV) Systems

7

Priority Assessment

Reliability – Medium

Power Quality – High

Redundancy – Medium

Low Initial Cost – Low

Long Term Ownership Cost – High

Flexibility – High

Optional Back-up Power

The server racks will most likely be the main equipment requiring optional back-up power. A

UPS is likely appropriate to serve these loads, though they may need additional long term back-

up power from a generator depending upon owner requirements.

Communications Systems and Building Services

Telephone/Data

Fire Alarm

- System shall annunciate at the fire alarm control unit and shall initiate

occupant notification upon activation

- Activated by: automatic fire detectors, automatic sprinkler system, manual

fire alarm boxes, and automatic fire-extinguishing systems.

Access Control

Security

Major Equipment Requiring Space

Mechanical equipment and motors, the generator, and panels will be the main equipment

requiring space. The building’s mechanical penthouse should provide adequate space for most

equipment, with some panels located in electrical closets on each floor.

Utility Rate Schedule

The campus is a customer of BGE – 13.2 kV is delivered to the campus delivery system, so the

campus is likely on the “P – Primary” rate schedule. However, because the URB is part of a

campus power distribution system, building power will not be metered individually by the

power company.

Voltage

Power is delivered to the building by the campus distribution loop at 13.2 kV. The building

transformer then drops the voltage down to 480Y/277.

Lighting – The existing lighting design primarily consists of 277V fixtures, however four fixture

types do require 120V power.

Receptacles – 120V

Mechanical – 277/480 3-phase power

Special Equipment – The special equipment is fed from a panel at 120/208V.

11

Emergency Loads

Panel E – Emergency Power: 4.7 kVA

Panel E feeds panel EP and emergency lighting loads. Panel EP powers elevator cab

lighting, the fire alarm control panel, and an air-compressor pre-action.

Panel S – Standby: 6.7 kVA

Panel S feeds panel SP, which in turn provides standby power to receptacles with

standby loads (in Biology lab and refrigerator loads), elevator pit lights, smoke dampers,

and a sump pump.

There appears to be an existing generator and generator panel “EDP” located beneath a parking

garage underneath the adjacent quad and a nearby building. The generator runs on diesel fuel.

Special Occupancy Requirements

No occupancy requirements were found, as the building does not contain a large lecture hall

which would count as an “assembly” occupancy.

Special Equipment

The URB features a raised floor system, and with this system it will utilize floor boxes in

many areas of the building. In many areas, these floor boxes will provide power into the office

furniture. These floor boxes and the furniture systems are both shown on the drawings and

listed in the specifications.

The building features one elevator, which is located on the North end of the building.

The elevator is shown on the drawings, and more information about the elevator systems can

be found in the building specifications.

Ceiling-mounted intercom speakers are located throughout the building, and can be

found on the AV drawings.

Telecommunications plans detail the locations of IT equipment and connections

throughout the University Research Building.

As the URB is home to the computer science department and several labs, there is likely

to be sensitive electronic equipment. At the time bid drawings were issued, it was known that

the bio lab would have sensitive equipment requiring standby power to receptacles. More

detailed information about other sensitive equipment was not available.

12

While conduit provisions were made for future photovoltaic installations on the flat roof

above the curved curtain wall of the building, there are not PV arrays in the current project as it

is being built.

UPS

There are no UPS types specified on the project.

Optional Back-up Power

Receptacles in the biology lab, as well as receptacles serving refrigerator loads, are

connected to optional back-up power. They are provided with this back-up power by the

standby panel, panel “SP”. In total, these optional back-up loads have a load of 0.4 kVA and they

are 120V receptacles.

Special/Communications Systems

Telephone/data – there are telephone and data connections throughout the URB.

Fire Alarm – fire alarm equipment is located throughout the building to alert occupants in the

event of an emergency.

Access control and security cameras will help to prevent unauthorized individuals from entering

the labs contained within the building.

15

Building Services

Cables will be installed to provide for both voice and data connections throughout the building.

Dedicated Electrical and Communications Spaces

Including the server room, there is 2,026 ft2 of dedicated electrical and communications space

within the building. This represents 2.89% of the total building S.F.

Energy Saving/Energy Cost Saving Techniques

There are not currently photovoltaic arrays included in the scope of the building project,

although conduit provisions were included to provide for future installations. The building uses daylight

harvesting with daylight sensors and dimmable light fixtures. The URB is pursuing LEED Gold

certification.

Part III – Evaluate As-Designed Systems vs. Initial Criteria

Estimated vs. Actual Loads

The estimated building load was about 1391 kVA, while the building as designed has a

connected load of about 898 kVA. One reason for the significant decrease is that the lighting loads

allowed by ASHRAE Standard 90.1 2010 (which has been adopted in Maryland) are much lower than the

W/ft2 listed in the NEC. While the actual receptacle connected loads were much higher than the

estimate based on NEC for an office building, there are significantly more receptacles in the lab areas of

the URB. Finally, the mechanical system as designed is much more efficient than the estimate made

based on R.S. Means Electrical cost data, as the mechanical system was designed to contribute to the

building’s LEED Gold rating.

Power Company Rate Schedule

There are not really any other options available for the university in terms of a utility rate

schedule, as they are already operating a university-owned campus distribution loop. As such, the

campus could consider participating in a Load Response Program, for which there is a rider, but this

would likely have to be approached on a campus-wide basis, as the URB is not individually metered.

16

Building Utilization Voltage

I would not suggest any changes to the building utilization voltage. The only change I might

suggest for the power distribution throughout the building would be to switch from the current

underfloor distribution system to a system like Snake Tray’s Snake Bus, which could provide increased

flexibility and cost-savings, especially through installation time and costs.

Emergency Power System

The URB appears to have all of the emergency power systems as required by code. I would not

suggest any changes to the generator system, as it is existing equipment that has already been designed

to power the surrounding buildings and the URB.

Equipment Specifications

The only changes I might suggest regarding the electrical equipment specified would be to

consider a Snake Tray bus system as mentioned above, and to provide UPS systems for some loads that

may benefit from increased power reliability.

Optional Back-Up Power and UPS Systems

I might suggest increased back-up power for some of the sensitive lab equipment and servers in

the building. There is still space available on the standby panel “SP”, and the exact loads and locations

may not have been specified in the bid drawings because the exact equipment and requirements may

not have been known at that time. I think a UPS system would be helpful to provide reliability to the

building’s server racks.

Reduced Cost of Ownership

The current design for the URB already specifies very high quality equipment, as it is on the

campus of a prestigious university. The equipment is also efficient, as the building is pursuing LEED Gold

certification.

17

Systems Integration

As ASHRAE Standard 90.1 already requires advances lighting controls in most of the spaces

throughout the building, one could consider integrating the building’s occupancy sensors with the

building’s mechanical system, to allow for more precise HVAC operation and increased energy savings.

The advantages of such an integrated system would be reduced HVAC costs, and lower equipment costs,

as you would not need to purchase separate occupancy sensors for both the lighting and mechanical

systems. However, this systems integration would likely have a high initial cost, and would require very

advanced coordination between the two systems. Furthermore, it could limit the lighting and

mechanical controls equipment that could be specified, as only some of the control systems are able to

effectively interface with each other.

Energy Cost Savings/Energy Reduction Techniques

The building design could consider the potential electric generation capabilities of actually

installing the PV arrays that the conduit has been provided for.
