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

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

April 9, 2008 9

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.”
