The Compton Union Building is the first building on WSU's campus to be LEED certified. The U.S. Green Building Council developed a green building rating system called the Leadership in Energy and Environmental Design (LEED) to provide a set of standards for environmentally sustainable construction.
In order to be LEED certified, a building must meet criteria in five areas:
- sustainable site development
- water savings
- energy efficiency
- materials selection
- indoor environment quality
The CUB incorporates several new, green-friendly features including water saving flush valves, efficient radiant heating and cooling, and extensive recycling facilities. Additionally, the building structure includes recycled construction material from the 2008 CUB renovation. During construction, over 90% of the building materials were recycled. Over 11 million pounds of debris removed from the CUB during the renovation avoided the Whitman County Landfill.
