A brief description of when and why the energy consumption baseline was adopted:
This year was aligned with the carbon footprint and also represented the year UC started tracking it energy usage and making changes on its campus based on sustainability.
Source-site ratio for imported electricity:
Total energy consumption per unit of floor area:
| Site energy | Source energy | |
| Performance year | 0.19 MMBtu per square foot | 0.22 MMBtu per square foot |
| Baseline year | 0.15 MMBtu per square foot | 0.27 MMBtu per square foot |
Percentage reduction in total source energy consumption per unit of floor area from baseline:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
UC runs an annual energy Conservation Challenge in its residence halls; see https://www.newsrecord.org/news/uc-sustainability-to-host-conservation-challenge/article_096bf7d8-44d1-11e9-80d1-2fa529cd68e2.html
A brief description of energy use standards and controls employed by the institution:
The University of Cincinnati’s campus is actively controlled by a comprehensive centralized building monitoring system (BMS). This BMS system allows for a sophisticated control of many of the largest pieces of equipment, lighting and HVAC systems operating throughout the campus buildings. Beyond the BMS, the preferred temperature control setpoints for the buildings during occupied periods at the university are 70°F heating and 75°F cooling. The University's staff sets back the temperatures and the airflows wherever possible. UC's unoccupied building temperature setpoints are 65°F heating and 78°F cooling. These unoccupied periods are determined by either an occupancy sensor or time of day schedule.

A brief description of co-generation employed by the institution:
UC's central plant is a tri-generation facility, efficiently producing electricity, steam and chilled water. See http://www.uc.edu/af/utilities/production.html

Data source(s) and notes about the submission:
Note that the figures reported for GSF do not match with PRE4. That's because the energy figures reported above include energy supplied to local area hospitals that are powered by the trigen plant operated by UC. Consequently the GSF of those hospitals (2,876,712 GSF) is also included in the numbers above. Since the hospitals are not included in any other credits in the STARS assessment (other than OP2 and OP5), their GSF is not included in PRE4.
