Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 527813 MMBtu 919585 MMBtu
Electricity from on-site renewables 0 MMBtu 0 MMBtu
District steam/hot water (sourced from offsite) 0 MMBtu 0 MMBtu
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) 2398706 MMBtu 1466505 MMBtu
Total 2926519 MMBtu 2386090 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year July 1, 2015 June 30, 2016
Baseline Year July 1, 2008 June 30, 2009

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):

For consistency's sake we have adopted a 2009 baseline across the board for all STARS operational credits, as that is the earliest year for which we have strong consistent data sets across categories.


Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 14510838 Gross Square Feet 13705694 Gross Square Feet

Source-site ratio for grid-purchased electricity:
3.14

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.20 MMBtu / GSF 0.17 MMBtu / GSF
Source energy 0.28 MMBtu / GSF 0.32 MMBtu / GSF

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:

Documentation (e.g. spreadsheet or utility records) to support the performance year energy consumption figures reported above:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):
---

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

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 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, e.g. combined heat and power (CHP):

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


A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):
