San Diego State University wins Best Practices Award for Monitoring Based Commissioning project at Campus Laboratory Building |
|
 |
San Diego State University was awarded the Best Practices Award for its Monitoring Based Commissioning Project at Chemical Sciences Laboratory at the 2006 UC/CSU/CCC Sustainability Conference. The commissioning team, consisting of Cogent Energy as the Commissioning Agent, Newmatic Engineering as the laboratory system commissioning contractor, and personnel from San Diego State University operations, were able to reduce energy usage in this energy intensive building by 15%. The commissioning team identified over 100 corrective actions which were implemented during the project. |
