Benchmarking Work Group
Facilitating development of the California benchmarking and infrastructure Collecting and organizing state facility data Modifying Portfolio Manager to meet California-
specific needs Automating energy data upload from utilities to
Portfolio Manager Extending benchmarking to all buildings
April 9, 2008 6
Benchmarking Goals
Develop infrastructure for automated benchmarking
Benchmark all state buildings Make benchmarking universally
available Use benchmarking to track progress
toward energy use reduction goals
PART 1
Benchmarking Overview
April 9, 2008 8
Benchmarking Defined
Benchmarking is the documentation of building energy use over time (e.g. monthly)
“…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-400-2005-051-CMF, September, 2005

How is benchmarking useful?
Users can: View facility information Track energy use over time Share facility information with others Apply for an Energy Star Building award
The State can: Aggregate energy use by Agency or State Track performance goals (e.g. 20% reduction)
April 9, 2008 10
Other Benchmarking Benefits
Track efficiency improvement effects Track multiple energy & water meters Customize meter names and info Monitor energy and water costs Set investment priorities
PART 2
California Benchmarking Process
April 9, 2008 12
State provides facility data
Facility identification name, location, year built, square footage
Optional facility info # of people, # of computers, op hours
Billing Meter identification Usually multiple meters & utilities
April 9, 2008 13
Utilities provide energy data
Monthly data from 2003 forward Automated uploads
PG&E, SMUD, SCE, SDG&E, SoCalGas Excel spreadsheets or printouts
All other utilities Must be uploaded by State personnel
April 9, 2008 14

Future of Benchmarking with AB1103
April 9, 2008 28
By January 1, 2009
Electric and gas utilities must… “maintain records of the energy
consumption data of all nonresidential buildings … for at least the most recent 12 months.”
“Upon written or secured electronic authorization … upload all of the energy consumption data for a building to the Energy Star Portfolio Manager...”
April 9, 2008 29
By January 1, 2010
Nonresidential building owners & operators must… “disclose Energy Star Portfolio Manager
benchmarking data and ratings, for the most recent 12-month period, to a prospective buyer, lessee, or lender… After the benchmarking data and ratings are disclosed, the property owner, operator, or his or her agent would not be required to provide additional information regarding the benchmarking data and ratings.”
