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

2009 is the baseline year for our work because that is the year that was used in our Climate Action Plan and we desire to maintain consistency in our reporting.

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

Gonzaga's buildings are heated to 70 degrees while occupied, 65 unoccupied. Buildings are cooled to 74 degrees when occupied.

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

Campus pathway and building flood lighting is, or has been converted to LED as well as all "Exit" signs, display lighting, and ceiling lighting.

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

In rooms deemed appropriate for lighting regulation for energy efficiency, lighting systems are equipped with occupancy sensors.

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

South and west facing windows provide passive solar heating to classrooms and offices during winter.

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

The John J. Hemmingson Center, opened in October 2015, uses ground source heating and cooling.

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:

The Recommissioned School of Ed. School of Law, Foley Library, and the Biology/Chemistry Building.

The Rosauer Center, the Law School, Foley Library and Hughes Hall have all been recommissioned by Plant Services.

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

Energy metering is monitired by Avista Utilities as well as Gonzaga University. Automated Logic controls are used to regulate heating and cooling for most buildings. Lucid BuildingOS helps with building intelligence work.

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

All new appliances purchased in the last few years have been Energy Star. All new boiler systems are high efficiency and condensing boilers. As are domestic hot water and swimming pool heating systems.

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

Drought tolerant native vegetation has been included in recent landscaping projects ie: Stevens Center.

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

We have used motion sensors to regulate the activation of vending machines.

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

Windows in 10 university residence halls and 3 apartment complexes were changed to thermal energy efficient windows in the last 3 years. When buildings are re-roofed white roofing surfaces are used to reflect the summer heat.
