Calculating Energy and Demand Retrofit Savings for Victoria High School: Interim Report
MetadataShow full item record
As part of the LoanSTAR program, Victoria High School in Victoria, Texas underwent two retrofits: a) an absorption chiller was changed to an electric vapor compression chiller, and b) an EMCS system was installed after about 5 months in the post retrofit period. Moreover, retrofit savings calculation was complex since pre-retrofit data consisted of only monthly utility data while hourly monitored data are available for the post-retrofit period. This report describes the method in which we have performed retrofit energy and demand savings in Victoria High School. A previous report described the procedure adopted when no pre-retrofit data are available. We have only used Unnormalized Utility Bills Comparison ,or the Level-0 approach to determine electricity (energy and demand) and gas energy savings for VHS.
