Cost-Benefit Analysis for Commissioning

Studies performed by Portland Energy Conservation, Inc. (PECI) indicate that the average operating costs of a commissioned building range from 8% to 20% below that of a non-commissioned building. BOMA cost data for office buildings suggests that building commissioning can result in energy savings of 20 to 50% and maintenance savings of 15 to 35%.Beyond operating efficiency, successful building commissioning has been linked to reduced occupant complaints and increased occupant productivity. The example below demonstrates the potential financial impact of increased occupant productivity.

Salaries dominate average annual commercial expenditures when compared to other operating costs such as facility operations and rent costs. For a standard office building of 250,000 sf, there are approximately 1500 occupants at an average salary of $40,000 each (taken from US Census Bureau March 2002). This equates to $78 million/year in salary expenses including fringe benefits. Analyzing potential cost savings, a 10-20% increase in productivity could result in an $8–16 million dollar impact each and every year.
