Evan Mills, PhD, staff scientist at Lawrence Berkeley National Laboratory (LBNL), has released an important report quantifying the costs and benefits of commissioning: “Building Commissioning: A Golden Opportunity for Reducing Energy Costs and Greenhouse Gas Emissions.”

Based on data from 37 commissioning providers representing 643 buildings comprising 99 million sq ft of floor space from 26 states the median cost for new-construction Cx amounted to $1.16 and would save13% on whole-building energy consumption. For existing buildings, the median cost amounted to $0.30 and median whole-building energy savings amounted to 16%. Payback times are 4.2 years for new construction, and 1.1 years for existing buildings.
