Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 12,959.71 MMBtu | 14,664.92 MMBtu |
| Electricity from on-site renewables | 0 MMBtu | 0 MMBtu |
| District steam/hot water (sourced from offsite) | 36,956.50 MMBtu | 45,301.80 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 0 MMBtu | 0 MMBtu |
| Total | 49,916.21 MMBtu | 59,966.72 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 30, 2012 |
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):
Fiscal year 2012 is used as the baseline because that is the first reporting period following the college's conversion of #6 fuel oil to a mix of #2 fuel oil and propane gas.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 577,747 Gross square feet | 639,000 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 | 0.09 MMBtu per square foot | 0.09 MMBtu per square foot |
| Source energy | 0.15 MMBtu per square foot | 0.16 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 | 6,240 Degree-Days (°F) |
| Cooling degree days | 614 Degree-Days (°F) |
Floor area of energy intensive space, performance year:
| Floor Area | |
| Laboratory space | 14,126 Square feet |
| Healthcare space | 2,800 Square feet |
| Other energy intensive space |
EUI-adjusted floor area, performance year:
Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
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):
We place "switch off" reminder cards on light switchplates in all administrative/academic building. We place reminder cards on computer lab monitors encouraging users to turn them off between uses. We remind faculty and students to turn off and unplug all energy using equipment during breaks.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
Where possible, temperature set-backs and set-points are used. Typically, a set point range around 68-70 degrees during heating period is employed and building systems, where these are adjustable, strive to achieve room temperatures within this set point range. Few buildings on campus are air conditioned but for those that are, summer a/c set points around 74-76 degree are employed.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
All screw-in incandescent light bulbs were upgraded to LED lighting. The gym recently was upgraded and lighting upgraded to LEDs as well.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Stratton Hall has south and west facing windows into the central atrium area so is able to employ some solar heat gain of the cement floor in that atrium area.
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
none
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):
As part of our Sustainable Procurement policy, we encourage users to purchase EnergyStar certified equipment. The IT group has standardized their computing equipment procurement on EPEAT certified (which includes EnergyStar standard compliance).
