Improved energy efficiency at the CWU Steam Plant: Waste heat recovery system.

A brief description of the innovative policy, practice, program, or outcome that outlines how credit criteria are met and any positive measurable outcomes associated with the innovation:

In June of 2015, CWU added a condensing heat exchanger (CONDEX) that captures the waste heat from the boiler’s flue gases and pumps it to Samuelson, Discovery Hall, and the upcoming Health Sciences building. As of now, the heat exchanger can heat the new 261,036 square feet of campus buildings without burning additional fuel, resulting in an 8% efficiency improvement.

Additional documentation to support the submission:

The CONDEX system was installed in June 2015, but has been used for two new buildings that came online in summer 2016 (Discovery Hall, formerly Science 2), and Samuelson (came online summer 2018). These two new buildings are being heated with waste heat recovery. A new Health Sciences building will also be heated by the Condex system.
