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

FY 2007 is the year that WSU became an ACUPCC signatory and made the commitment to become a carbon neutral campus. This is the year we have used as our baseline for all of our ACUPCC reports and all internal reporting.

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

During business hours we have a heating set point of 70 degrees and a cooling set point of 74 degrees. When the buildings are unoccupied we have a heating set point of 55 degrees and a cooling set point of 83 degrees. Most campus buildings operate on building timers using the BAS (Building Automation System). The main campus uses Johnson Control's Metasys, and the Davis Campus uses Atkinson's Staeffa Talon.

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

There are various applications of LED building lighting and accent lighting on campus. Most notably we converted our Dee Events Center arena lighting over to LED.

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

About half of our buildings on campus employ the use of dual technology occupancy sensors and the rest are in the process of being converted over to this technology.

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

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

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

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

As of fall 2013 WSU has started recommissioning at least two buildings per year. Buildings with the poorest EUIs and largest number of occupant complaints have the highest priority for recommissioning.

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

The campus utilizes the JCI Metasys which works as an energy management system. Over 95% of WSU's campus buildings are now sub-metered with data available for public viewing through our Lucid Dashboard system which can be found at: http://buildingdashboard.net/weber/

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

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

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

Almost all vending machines on campus are on vending misers.

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