Buildings Behave the Same Way! Source: Federal Energy Management Program, O&M First! – A Case Study on In-house Retrocommissioning at a DOE National Laboratory, June 2004 “Numerous case studies have been completed over the years with resulting O&M-related energy efficiency improvements on the order of 5–30% covering a wide range of building uses.” Federal Energy Management Program U.S. Department of Energy
