Continuous Commissioning® of the Matheson Courthouse in Salt Lake City, Utah

The Utah Energy Office, located in the Department of Natural Resources (DNR), Utah Department of Facilities Construction and Management (DFCM), and engineers from the Energy Systems Laboratory at Texas A&M University teamed to perform Continuous Commissioning® 1 of the Matheson Courthouse in Salt Lake City, Utah. The Matheson Courthouse is a relatively new building, well-run, with a modern controls system. It is one of the most efficient buildings in Utah, averaging only $1.08 per square foot per year prior to the building and thermal plant commissioning. The project started with a walk-through commissioning audit in February 2001, and the CCSM process began in January 2002. Details of the CC process and the measures implemented are included in this paper. The 2002 energy bills for Matheson dropped by $116,000, down to $0.77 per square foot per year. Approximately 80% of the reduction in bills can be attributed to the Continuous Commissioning process, with the remaining savings coming from lower gas and electricity prices
