A brief description of when and why the building energy consumption baseline was adopted:

Opted to use the three year average in order to account for seasonal variations in energy use. July-June was used because it is the universities fiscal year, and is the common time period that records are kept in.


A brief description of any building temperature standards employed by the institution:

See link for temperature set point policy: http://www.fm.wmich.edu/index.php/download_file/-/view/520


A brief description of any light emitting diode (LED) lighting employed by the institution:

WMU is utilizing LED technology for new exterior applications, as well as certain interior applications. We have also eliminated the use of HID, incandescent, and CFL fixtures in new construction. New construction will exclusively utilize T8 fluorescent and LED.


A brief description of any occupancy and/or vacancy sensors employed by the institution:

Occupancy/Vacancy sensors are utilized in new construction per ASHRAE 90.1, and have been retrofitted across campus.


A brief description of any passive solar heating employed by the institution:

N/A


A brief description of any ground-source heat pumps employed by the institution:

N/A


A brief description of any cogeneration technologies employed by the institution:

WMU utilizes 2 natural gas cogeneration turbines as part of the main campus power plant. These turbines have a combined output of approximately 11 Mw.


A brief description of any building recommissioning or retrofit program employed by the institution:

N/A


A brief description of any energy metering and management systems employed by the institution:

WMU meters all utilities at the building level. Some buildings are also sub metered. WMU also manages energy consumption through its Building Automation System.


A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:

WMU has a Energy Star purchasing policy for all qualifying energy consuming appliances, including but not limited to computers, printers, monitors, and refrigerators.


A brief description of any energy-efficient landscape design initiatives employed by the institution:

N/A


A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:

N/A


A brief description of other energy conservation and efficiency initiatives employed by the institution:

WMU utilizes a heat recovery system to transfer waste heat from its ice arena to its swimming pool. WMU utilizes CO2 monitoring to reduce the required outside air brought into buildings.
