1. Benchmarking State Buildings Karen Herter, Heschong-Mahone Group (HMG) Mike Langley, Dept. of General Services (DGS) April 8, 2008

2. April 9, 20082 Executive Order S-20-04 Governor California Energy Commission Benchmarking Work Group

3. April 9, 20083 S-20-04 Directives Benchmark all occupied State buildings Reduce energy use 20% by 2015  From the 2003 baseline  Encourage all commercial buildings to do likewise

4. April 9, 20084 California Energy Commission Chose U.S. EPA’s Portfolio Manager at http://www.energystar.gov/benchmark Formed the Benchmarking Work Group  US EPA  California State agencies  California energy utilities  Private sector

5. April 9, 20085 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

6. April 9, 20086 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

7. PART 1 Benchmarking Overview

8. April 9, 20088 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

9. April 9, 20089 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)

10. April 9, 200810 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

11. PART 2 California Benchmarking Process

12. April 9, 200812 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

13. April 9, 200813 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

14. April 9, 200814 State Benchmarking Status State Facility Data: Done Utility Energy Data: ~70% Done Data Quality Control: ~40% Done

15. April 9, 200815 State Facility Data

16. April 9, 200816 Next Steps and Schedule April 2008  Finalize data: PG&E residential, MUNIs, State Natural Gas Program  Final report for all State buildings May 2008  Present results at Green Action Team meeting

27. PART 4 Future of Benchmarking with AB1103

28. April 9, 200828 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...”

29. April 9, 200829 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.”
