Is retro-commissioning an existing building an effective energy reduction strategy?
To quote the most recent study on commissioning from the Lawrence Berkeley National Laboratory (LBNL):
“The results demonstrate that commissioning is arguably the single-most cost-effective strategy for reducing energy, cost and greenhouse-gas emissions in the buildings today.”
While median commissioning costs for existing buildings are $.30/s.f.; median annual energy savings achieved are 16% and the median payback period is 1.1 years.
LBNL used data from 643 buildings, representing 99 million s.f. of space to develop the report.
