Benchmarking Defined n Benchmarking is the documentation of building energy use over time (e. g. monthly) n “…a beginning step in managing a building’s energy cost, one that should motivate the building’s owner or manager to take actions to improve the building’s energy profile. ” (CEC 2005) Benchmarking System for California Commercial Buildings - Plan, Timetable, and Recommendations, CEC Report CMF-400 -2005051 -CMF, September, 2005 March 12, 2007 3
How is benchmarking useful? n Portfolio Manager gives users the ability to: ¡ ¡ n Track energy use over time View facility information in customized reports Share your facility information with Agencies and the State Apply for an Energy Star Building label Portfolio Manager gives the state the ability to: ¡ ¡ March 12, 2007 View and aggregate energy use by Agency or State Track State performance goals (e. g. 20% reduction goal) 4
Benchmarking Task #1 n Annual energy usage “baseline” ¡ ¡ n n Provide: Facility info and energy data Receive: Normalized source k. Btu/ft 2 California State baseline year is 2003 Use to track 20% energy reduction goal March 12, 2007 5
Tracking Reduction Goals March 12, 2007 6
Benchmarking Task #2 n Energy Performance Rating ¡ ¡ n n Percentile score between 1 and 100 Normalized by weather, building size, location, etc. 75+ for Energy Star Buildings Award Use to compare buildings to each other March 12, 2007 7
Comparing Buildings Likely candidates for efficiency improvements March 12, 2007 8
Other Benchmarking Benefits n n n Track efficiency improvement effects Track multiple energy & water meters Customize meter names and info Monitor energy and water costs Share building data Set investment priorities March 12, 2007 9
