Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 72,963.52 MMBtu 68,474.33 MMBtu
Electricity from on-site renewables 0 MMBtu 0 MMBtu
District steam/hot water (sourced from offsite) 50,000 MMBtu 45,666.70 MMBtu
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) 16,000 MMBtu 25,400 MMBtu
Total 138,963.52 MMBtu 139,541.03 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year July 1, 2016 June 30, 2017
Baseline Year July 1, 2011 June 29, 2013

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):

Emerson College has grown and dramatically since we began tracking emissions in 2007. While Emerson continues to grow and revitalize its spaces, the majority of the current campus was in operation beginning January 2010. For this reason, I have set the baseline year to be an average of FY11, FY12, and FY13, to better reflect the general resource use and associated emissions, both per capita and per square foot.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 1,429,317 Gross square feet 1,429,317 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 0.10 MMBtu per square foot 0.10 MMBtu per square foot
Source energy 0.21 MMBtu per square foot 0.21 MMBtu per square foot

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 5,181 Degree-Days (°F)
+ Date Revised: Sept. 5, 2019
Cooling degree days 884 Degree-Days (°F)
+ Date Revised: Sept. 5, 2019

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

EUI-adjusted floor area, performance year:
1,450,847 Gross square feet

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

Documentation (e.g. spreadsheet or utility records) to support the performance year energy consumption figures reported above:
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):

Green Room Certification in residence halls promotes sustainable energy practices regarding appliances, lighting, elevator use, and temperature regulation.
The Green Etiquette Training program provides administrative assistants tools to lower their offices' energy consumption.

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

Lighting and heating controls and sensors are employed in all of our buildings, with a particular emphasis on our administrative buildings.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

LED lighting is the primary lighting in all of our buildings, including stairwells, basements and historic theaters. All new lighting installed is LED.

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

We have white roofs to deflect light on our buildings to deflect light and mitigate the urban island effect.

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

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):

By 2018 the majority of our buildings will be LEED certified and we buy energy-star rated (or similar) products for all of our appliances.

Recent energy and resource saving projects:
- Replaced the lone boiler on campus in Union Bank building with district steam for heading and added a domestic water preheat plate exchanger, reducing our CO2 emissions by 75%.
- Installed new chillers and building automation in Union Bank building
- Installed new building automation in Walker building
- Recommissioned building automation and HVAC systems at 10 Boylston Place (new building)
- Retrofit lighting in classrooms to 2x2 LED drop-in fixtures
- Installed smart strips in residence hall common rooms
- Replaced loading dock lights at Paramount Center with LEDs
- Installed thermostats and set back clocks for baseboard heat in Ansin Building
- Eliminated 1 of 4 lighting fixtures in Walker building hallways
Installed VFD controllers on chillers in Piano Row building
