Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 63,923.67 MMBtu 67,002.99 MMBtu
Electricity from on-site renewables 0 MMBtu 0 MMBtu
District steam/hot water (sourced from offsite) 0 MMBtu 0 MMBtu
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) 97,690.97 MMBtu 94,625.29 MMBtu
Total 161,614.64 MMBtu 161,628.28 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year July 1, 2017 June 30, 2018
Baseline Year July 1, 2016 June 30, 2017

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 2,413,802 Gross Square Feet 2,329,470 Gross Square Feet

Source-site ratio for grid-purchased electricity:

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.07 MMBtu / GSF 0.07 MMBtu / GSF
Source energy 0.12 MMBtu / GSF 0.13 MMBtu / GSF

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 5,363 Degree-Days (°F)
Cooling degree days 535 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 12,656 Square Feet
Healthcare space 0 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
2,472,257 Gross Square Feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
11.08 Btu / GSF / Degree-Day (°F)

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):

Starting in 2016 we added the Warrior's Energy Cup Challenge to the annual Campus Sustainability Week held in October. For a week, Students living in residence halls on campus compete to reduce their energy use. The hall that reduces its energy use the most earns points towards the broader Dean's Cup.

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

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.

In Eastern's Library, Gelsi-Young Hall Administration Building, Fine Arts Instructional Center, and the Student Center there has been installation of an Encelium Energy Control System that utilizes six different energy management strategies in order to maximize energy savings.

The Encelium system utilizes the following strategies to maximize energy savings:
-smart-time scheduling for zones not appropriate for occupancy sensors,
-daylight harvesting to the adjustment of lighting levels based on natural sunlight,
-task tuning to avoid over lighting particular areas,
-occupancy controls to automatically turn lights off when not needed,
-personal controls so individuals can set their own workspace preferences, and
-light dimming to shave peak demand and reduce energy consumption.
We can track performance by building, year to year to manage consumption and loads.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies 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 the two parking garages, and athletic complex parking lot. Lighting was retrofitted to LED in the Facilities Management building and the corridors and common spaces of Noble Hall in summer 2018.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

Our nine-story residence hall, High Rise, has geothermal heating and cooling.

A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):

The Science Building has a 400kw fuel cell which converts natural gas into electricity and both high and low-grade heat for the building. In 2017 we replaced the 400kw fuel cell with a 440kw fuel cell.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):

Eastern has been retro-commissioning buildings through utility incentive programs. We are embarking on retro-commissions for the Fine Arts Instructional Center.
