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.

Optional Fields
A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
The Sustainability and Environmental Management Office (SEMO) has also published several green living guides to provide guidance to residential students, including for Sustainable Events and Sustainable Holidays, that provide tips for reducing environmental impacts.
A brief description of energy use standards and controls employed by the institution:
Faculty, staff and students are encouraged to set their thermostats to 68 degrees F in the winter and 75 degrees F in the summer. During the summer and winter breaks, when most students and many staff are off campus, temperatures are centrally controlled by Plant Operations in order to keep energy usage down.
When spaces are unoccupied, automatic setbacks are implemented to reduce energy use. For example, automatic setbacks are in place at night for office spaces and classrooms that are not in use during that time.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
A brief description of co-generation employed by the institution:
The decommissioning of the plant’s last coal boiler in December 2014 brings the power plant’s 126-year reliance on coal to an end. The modern structure, built in 1962, has been partially powered by natural gas since 1988, but still burned 105 million pounds of coal and produced 15 million pounds of ash waste per year. Authority (TVA).
The environmental benefits of the conversion are significant. Greenhouse gas emissions—the carbon footprint of the power plant—will go down by as much as 40 percent. The conversion will also decrease the emission of particulate matter by more than 50 percent and virtually eliminates emissions of mercury, hydrogen chloride, sulfur dioxide and other air pollutants.
Operationally, converting to natural gas will make the plant more efficient, require far less maintenance and be more reliable. Additionally, it will be better able to meet stricter EPA regulations.
