The Cost-Effectiveness of Continuous Commissioning® Over the Past Ten Years
MetadataShow full item record
Continuous Commissioning® data including savings, costs, and implemented measures from over 60 buildings and sites commissioned by staff from the Energy Systems Laboratory at Texas A&M University are presented. Measured annual whole building data is included and is used to calculate indicators describing energy savings, commissioning cost, and the relationship between the two. The measures are organized by component and type and analyzed for frequency of implementation. The average unit area savings for the data set is $0.51/(ft2a) ($5.52/(m2a)) with an average annual energy cost savings of 14%. The average cost of commissioning is $0.43/(ft2a) ($4.60/(m2a)) resulting in an average simple payback of 1.6 years. Just over half of the measures implemented are related to air handling and distribution and 13% of the total number of measures implemented are advanced resets of air side systems. Overall, the analysis reinforces previous studies demonstrating the effectiveness of Continuous Commissioning®.
