A brief description of when and why the building energy consumption baseline was adopted:


A brief description of any building temperature standards employed by the institution:

Heating cooling range is set at between 69-and 73 degrees Fahrenheit according to Connecticut state statutes. The state has guidelines for the start dates of heating and cooling seasons which Eastern abides by.

A brief description of any light emitting diode (LED) lighting employed by the institution:

LED lighting is utilized in exterior site lighting throughout most of the campus. Interior LED lighting is also utilized at Hurley Hall dining area and bathrooms, Webb Hall faculty office wing hallway lighting, Student Center recessed lighting, Constitution, Nutmeg and Laurel residence hall elevators, and Burnap residence hall bathrooms, and athletic complex parking lot.

A brief description of any occupancy and/or vacancy sensors employed by the institution:

Occupancy sensors are utilized throughout most of the campus including, classrooms, labs, offices, support spaces, The campus has begun to utilize a lighting control system (Encelium) which ties into the Building Automation System and is utilized in managing lighting levels within the building. It also allows individual users to dim their lights as necessary. This includes time of day scheduling for on and off, controls air handlers, VAV boxes and exhaust fans, from occupied to unoccupied set points. We are currently using this system in the Library, the Student Center, and Gelsi-Young.

A brief description of any passive solar heating employed by the institution:


A brief description of any ground-source heat pumps employed by the institution:

Geothermal Energy: Three wells pump water to heat pumps, or to chiller depending on the demand of the building and the season. Temperature of ground water is 53 degrees Fahrenheit.

A brief description of any cogeneration technologies employed by the institution:

The Science Building has a 400kw phosphoric acid fuel cell which provides electricity and both high and low-grade heat for the building.

A brief description of any building recommissioning or retrofit program employed by the institution:

Eastern has been retro-commissioning buildings through utility incentive programs.

A brief description of any energy metering and management systems employed by the institution:

Eastern sub-meters almost all of their buildings for electricity, heat and hot water. This metered data feeds into our Energy Dashboard which monitors energy use by building every 15 minutes.

A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:

The IT department regularly replaces outdated computers on campus with newer, more energy efficient models. Other equipment is also replaced using ENERGY STAR appliances including washers, dryers, stoves etc.

A brief description of any energy-efficient landscape design initiatives employed by the institution:

A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:

Eastern uses vending misers on the vending machines which operate based on occupancy sensors.

A brief description of other energy conservation and efficiency initiatives employed by the institution:

Eastern has converted its fuel use from oil to natural gas which provides a higher level of efficiency.

The website URL where information about the institution’s energy conservation and efficiency initiatives is available:

This information was collected using data from Eastern's benchmarking report reported by ISE staff Mimi Cedrone. Other information about buildings was collected from Facilities staff Shellena Pitterson.

Laboratory space was calculated using 25,755 sq. ft. (Class laboratories for EES, Physical Science and Biology ONLY).

Other energy intensive space was calculated using 51,263 sq. ft. (This includes all other class laboratories, open laboratories, non-research laboratories, data centers, green houses, TV station, Student Center kitchen and pot wash area, Hurley Hall fridge area, pot wash area, food prep area, bakery, server area behind serving stations, computer laboratories – study rooms and 4th floor of Webb Hall.)
