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 | 61,786,938 Kilowatt-hours | 210,817.03 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 | 43,692 MMBtu |
| Imported steam, hot water, and/or chilled water | 0 MMBtu |

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
In November 2021, the CSD hosted a Energy Efficiency Workshop with a community partner, the Sustainability Institute. The goal of the workshop was to provide renter/friendly tips and techniques to conserve energy and water use at low or now cost.
A brief description of energy use standards and controls employed by the institution:
---
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The College kicked off an Energy Savings Performance Contract in July 2021 that aimed to reduce emissions and save the College approximately $1.7 million annually. The project, led by Facilities Management, engages almost every building on campus through the replacement of light bulbs to more efficient alternatives, replacement of shower heads and to low-flow fixtures as well as larger scale projects such as building envelope improvements and building automation systems.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
A geothermal unit was placed in 5 College Way during the historic home's renovation as a pilot for possible expansion to any of our more than 50 historic homes on campus.
