A Methodology for Identifying Retrofit Energy Savings in Commercial Buildings
MetadataShow full item record
Measured energy savings resulting from energy conservation retrofits in commercial buildings can be used to verify the success of the retrofits, determine the payment schedule for the retrofits, and guide the selection of future retrofits. This paper presents a structured methodology, developed for buildings in the Texas LoanSTAR program, for measuring retrofit savings in commercial buildings. This methodology identifies the pre-retrofit construction and post-retrofit periods, normalizes energy consumption data, and quantifies the uncertainty associated with the measured savings. A case study from the Texas LoanSTAR program is presented as an example.
