"---" indicates that no data was submitted for this field

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 267,114 MMBtu 273,612 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) 436,233 MMBtu 473,880 MMBtu
Total 703,347 MMBtu 747,492 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year June 1, 2015 May 31, 2016
Baseline Year June 1, 2014 May 31, 2015

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 6,418,470 Gross square feet 6,392,681 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 0.11 MMBtu per square foot 0.12 MMBtu per square foot
Source energy 0.20 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 5,397 Degree-Days (°F)
Cooling degree days 1,030 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 442,146 Square feet
Healthcare space 10,039 Square feet
Other energy intensive space

EUI-adjusted floor area, performance year:
7,358,208 Gross square feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
14.87 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):

Both the Sustainability Office and the Energy Management Group market the campus community throughout the year. For example, we run several campaigns throughout the year to raise awareness and make special efforts to save energy of student breaks. In addition, we started a summer focused campaign to solicit campus community help in shaving the peak electric demand. Both offices are also involved with students and faculty through various research projects.

Institutional demand response

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

Boston College use multiple building automation systems to assist with the control of temperature throughout campus: Johnson Controls Metasys, Schneider Electric Structureware and Continuum. Our design standards ensure that occupancy sensors are installed in new construction and renovations. Schedules are continuously improved to turn down temperature controls while spaces are unoccupied.

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

Boston College commits substantial annual funding to retrofit existing buildings with the most energy efficient lighting strategies. In addition, all new construction employs LED standards throughout.

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


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

A small cogeneration system is employed to support a residential housing building on campus.

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):

Equipment and appliances have been replaced through Energy Star programs throughout the campus. Several efforts have been launched to recommission campus buildings, especially the energy intensive buildings. Additionally, we employ a continuous commissioning program in 10 of our campus buildings. Boston College is on its third cycle of cooperation with our electrical supplier. This agreement is codified in a memorandum of understanding that commits the institution to save over 2M KWh per year over the last 7 years which has been successfully accomplished.
