Part 2. Reduction in source energy use per unit of floor area
Baseline year energy consumption
STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.
| kWh | MMBtu | |
| Imported electricity | 15,078,517 Kilowatt-hours | 51,447.90 MMBtu |
| Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 0 Kilowatt-hours | 0 MMBtu |
Stationary fuels and thermal energy, baseline year (report MMBtu):
| MMBtu | |
| Stationary fuels used on-site to generate electricity and/or thermal energy | 91,481 MMBtu |
| Imported steam, hot water, and/or chilled water | 0 MMBtu |
Total site energy consumption, baseline year:
Baseline year building space
Baseline period
| Start date | End date | |
| Baseline period | July 1, 2010 | June 30, 2011 |
A brief description of when and why the energy consumption baseline was adopted:
The baseline year was adopted as the first year that a completed GHG inventory was performed in accordance with ACUPCC requirements, and the year we were required to make our first inventory submittal under the ACUPCC program.
Source energy
Total energy consumption per unit of floor area:
| Site energy | Source energy | |
| Performance year | 0.08 MMBtu per square foot | 0.13 MMBtu per square foot |
| Baseline year | 0.10 MMBtu per square foot | 0.16 MMBtu per square foot |

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
A brief description of energy use standards and controls employed by the institution:
Recently the College completed a multi-year project that replaced its 1990s vintage campus building automation system (BAS) with a state of the art AutomatedLogic WebCTRL BAS which has enabled increased efficiences via finer control. Newly contructed & renovated spaces employ occupany and vacany sensors. Heating season set points are 66 to 70 occupied and 62 to 66 unoccupied. Cooling season set points are 76 to 80 occupied and 80 to 84 unoccupied.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The lighting in all newly constructed and renovated spaces is LED, typically with occupany or vacancy sensors as a minimum, day light sensor control as appropriate and incorporated into our new BAS. The majority of lighting in other existing spaces has been upgraded; we have plans for further upgrades. Exterior site and building lighting has all been upgraded to LED in the past 3 to 4 years.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
The Athletic Centers uses a rooftop evacuated tube solar collection array to pre-heat its domestic hot water and also to provide space heating for the main lobby.
A brief description of co-generation employed by the institution:
There is no co-generation or combined heat and power at the College. Rather the College is pursuing several potential off-site renewable energy procurement options.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
All new appliances and equipment are Energy Star rated. Replacement of old boilers with condensing boilers is common. The Athletic Center and East Wing of the Science Center have been retro-commissioned and the Dining Center, West Wing of the Science Center and a major administrative building are all scheduled to be retro-commissioned this year. In the past six years a science lab, the visual arts/media center and main library have been completely renovated to LEEDS standards. Currently a project to provide new and renovated space for the Music department is progress.
