Part 1
This credit is based on energy inputs from offsite sources and electricity produced by onsite renewables. When the institution purchases one fuel and uses it to produce heat and/or power, you should enter only what is purchased. For example, if the institution purchases natural gas to fuel a CHP system and produce steam and electricity, only the purchased natural gas should be reported.
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 54,261.19 MMBtu | 58,197.35 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) | 105,057.85 MMBtu | 102,897.48 MMBtu |
| Total | 159,319.04 MMBtu | 161,094.83 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, 2012 | June 30, 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):
The building energy consumption baseline was adopted to align with the baseline chosen for the greenhouse gas credit. Fiscal Year 2013 was the most recent greenhouse gas inventory available.

| Gross floor area of building space | 149,564.54 Gross square meters | 133,408.71 Gross square meters |
Source-site ratio for grid-purchased electricity:
3.14
Total building energy consumption per unit of floor area:
| Performance Year | Baseline Year | |
| Site energy | 1.07 MMBtu per square meter | 1.21 MMBtu per square meter |
| Source energy | 1.84 MMBtu per square meter | 2.14 MMBtu per square meter |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
13.99

Optional Fields
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):
---
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
The College uses central controls to maintain a temperature of between 68 and 74 degrees during the heating season. Over winter break, the temperature is set-back to 58 degrees in unoccupied spaces.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The College has completed several lighting upgrades including converting facilities in the Athletic Center, outside lighting, and a performance hall to LEDs.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
The College has a geothermal system that provides all of the heating and cooling of New London Hall, one of our science facilities.
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):
The College recently completed a project to upgrade the kitchen hoods in all dining hall kitchens to variable speed fans.
