Grid-purchased electricity 116,819 MMBtu 93,541 MMBtu
Electricity from on-site renewables 553 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) 115,521 MMBtu 114,327 MMBtu
Total 232,893 MMBtu 207,868 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):

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):

The college launched the "Energy Can't Save Itself" campaign in 2015. Large scale decals installed in high-traffic areas and computer labs across the college provide tips on energy conservation. A page was also dedicated on the Office of Sustainability's website to energy saving tips at school, work and home. The energy awareness campaign was heavily promoted on social media.


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

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

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 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):
