Building Commissioning PhilosophyTotal Building Commissioning GSA is responsible for meeting the space requirements of federal agencies. To assure a high standard of excellence for the American public, GSA utilizes a Total Building Commissioning Process. Total Building Commissioning is the Public Buildings Service’s (PBS) process for quality delivery in new construction and facility modernization. It is the process for achieving, validating and documenting that the performance of the total building and its systems meet the design intent and requirements of the owner. Defining Commissioning for GSA Buildings The National Conference on Building Commissioning has established an official definition of ‘Total Building Commissioning’ as follows:
Historically, the term “commissioning” has referred to the process by which the heating, ventilation and air conditioning (HVAC) systems of a building were tested and balanced according to established standards prior to acceptance by the building owner. Today’s use of commissioning recognizes the integrated nature of all building systems’ performance, which impact sustainability, workplace productivity, occupant safety and security. As reflected within the Facilities Standards for the Public Buildings Service (P-100), GSA accepts ‘Building Commissioning’ practices as described above and within this Guide. Prospectus level projects (new and modernization) planned for 2006 and thereafter shall adopt a Total Building Commissioning practice beginning with the project planning stage and concluding with the post occupancy evaluation phase. These projects shall include provisions for Total Building Commissioning cost in their budget. For projects that have already received funding approval prior to 2005, a limited commissioning practice shall be adopted to meet project performance objectives.
Because all building systems are integrated, a deficiency in one or more components can result in suboptimal operation and performance among other components. Remedying these deficiencies can result in a variety of benefits including:
Industry sources indicate that on average the operating costs of a commissioned building range from 8% to 20% below that of a non-commissioned building. Certain available commissioning implementation tools, such as cost shared USDOE Energy Contractors, may even result in a negative capital investment cost. GSA’s goal in adopting building commissioning is:
