Utilities Support Green Building Initiative (GBI) Benchmarking
• Utilities and State reps
working on benchmarking,
include:
– Mike Langley – DGS
– Steve Prey – Caltrans
• Utilities offer Integrated
Demand Side
Management services
for identified buildings
3
Benchmarking Benefits
• Consistent tool across utility service areas
• Monthly side-by-side comparisons of building energy intensity (kBTU/sq ft)
• Identification of candidates for energy efficiency, demand response or self
generation
• On-going tracking tool for agency’s building portfolio
4
Benchmarking Process
• EPA’s ENERGY STAR®
Portfolio Manager to
determine GBI metrics
(kBTU/sq ft)
• 2003 – 2015: Automatic
upload of monthly meter
data
• Buildings served by multiple
utilities included
5
Data Transfer & Storage
• Utilities need State’s authorization to release meter data to EPA’s ENERGY STAR® Portfolio Manager
• PG&E has confirmed that EPA database is secure for transmission and storage of confidential data
• PG&E has successfully uploaded test data using new Unix-based XML utility – first time EPA has allowed non-Windows based upload
6
Next Steps
• Data release authorization for identified State buildings – In Progress
• Start the upload of monthly data from 2003-now for identified State buildings by 12/31/06
• Further automation and enhancements by State, Utilities and EPA in Q4-06 and 2007
7
Planned Tool & Report Enhancements
• Show other units (kWh, therms, lb stm) with kBTU and cost displays
• Provide grouping by Facility, Dept, Agency, Utility and State
• Provide group totals b
• Provide graphs comparing energy use by building type, year or other factors
