Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 152,439 MMBtu | 119,666 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) | 153,765 MMBtu | 178,663 MMBtu |
| Total | 306,204 MMBtu | 298,329 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2016 | June 30, 2017 |
| Baseline Year | July 1, 2011 | June 30, 2012 |
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):
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 3,968,910 Gross square feet | 3,398,494 Gross square feet |
Source-site ratio for grid-purchased electricity:
Total building energy consumption per unit of floor area:
| Performance Year | Baseline Year | |
| Site energy | 0.08 MMBtu per square foot | 0.09 MMBtu per square foot |
| Source energy | 0.16 MMBtu per square foot | 0.16 MMBtu per square foot |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
Degree days, performance year (base 65 °F / 18 °C):
| Degree days (see help icon above) | |
| Heating degree days | 5,041 Degree-Days (°F) |
| Cooling degree days | 1,285 Degree-Days (°F) |
Floor area of energy intensive space, performance year:
| Floor Area | |
| Laboratory space | 79,201 Square feet |
| Healthcare space | 13,193 Square feet |
| Other energy intensive space |
EUI-adjusted floor area, performance year:
Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
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):
WCU uses a web based digital control HVAC management system. Room climate is determined by room schedules and occupancy. There is a night set-back for all the buildings that are digitally controlled
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
WCU uses LED lighting in fixtures. We have eliminated all of the inefficient old T-12 fluorescent lamps and standard ballasts. These have been replaced with T-8 lamps and in some cases T-5 lamps. We use energy efficient electronic ballasts.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
The campus geothermal system was proposed in 2007 as a means of updating the coal-fired steam plant and electric chillers on-campus. The district geothermal system currently involves 12 buildings:
Francis Harvey Green Library
Business and Public Management Center
Mitchell Hall
Student Recreation Center
Recitation
Ruby Jones
Anderson Hall
Hollinger Field House
Wayne Hall
and the residence halls Allegheny, Commonwealth, and Brandywine.
The President's House (Tanglewood), 25 University, the E.O. Bull Center, and the Village and Village East Apartments use individual geothermal systems separate from the main district geothermal connections. There are 887 wells (as of 3/30/18) with an anticipated total of over 1,000.
The geothermal system runs by removing excess heat from inside buildings, accumulated by body mass and solar energy, and storing it in below-ground water wells. Due to the high specific heat of water, this heat can be stored as energy so that when heating needs are required on cooler days the automatic, remote computer system will pump the stored heat back into the building.
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
N/A
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):
West Chester University is completing an initial 15-year guaranteed energy savings agreement and is in the process of developing a second to extend into the future. These agreements have involved lighting improvements, controls upgrades, water conservation, HVAC system improvements, and other measures.
