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.
A brief description of co-generation employed by the institution:
