ENERGY STAR National Manager, Public Sector
US EPA
September 2009
A government-backed, voluntary program that helps businesses and individuals protect the environment through superior energy performance by providing energy-efficient solutions for homes, businesses, and institutions.
The national symbol for environmental protection through energy efficiency, recognized by more than 75% of all U.S. households.
What is ENERGY STAR for
Commercial Buildings?
• U.S. Environmental Protection Agency energy management program.
• Offers proven solutions to help building owners and managers reduce energy consumption.
• Program for new construction and existing buildings.
• Works in markets with a focus on:
– Commercial property (offices, retail, hotels)
– Public sector (government, K-12, higher ed)
– Healthcare
– Small business and congregations
Commercial buildings and industrial facilities generate about 50 percent of U.S. carbon dioxide emissions.
30 percent of energy consumed in commercial and industrial buildings is wasted.
Energy costs represent a typical school district’s second largest operating expense, after salaries — more than the cost of computers and textbooks combined.
Reductions of 10 percent in energy use can be possible with little or no cost.
• EPA challenges school districts across the United States to save 30% through
ENERGY STAR
– Nearly 2,000 K-12 buildings have earned the
ENERGY STAR
– 58 (out of 70 total) school districts have been recognized by EPA for saving 10% to 40% districtwide
– More than 16,000 K-12 school facilities have been benchmarked in ENERGY STAR Portfolio

Assess Performance for Strategic
Energy Management
1.
Identify best opportunities for savings
2.
Track progress over time
3.
Verify savings from upgrade efforts
1. Identify Best Opportunities for
Energy Efficiency Improvements
• Identify under-performing buildings to target for energy efficiency improvements.
• Estabish baselines to set goals and measure progress
2. Track Progress Over Time
• Set a baseline and monitor energy efficiency improvements over time
• View percent improvement in weather-normalized energy use intensity.
• Track reductions in greenhouse gas emissions.
• Monitor energy and water costs
3. Verify Savings Results
• Provide transparency and accountability to help demonstrate strategic use of capital improvement funding.
• Quickly and accurately demonstrate savings for an individual building or entire portfolio:
– Energy use
– GHG emissions
– Water use
– Energy costs
Portfolio Manager
Four Simple Steps

Utility Supported ABS
• Pacific Gas & Electric Company (PG&E)
– Automated Benchmarking Program began in 2007
– Launched the “More Than a Million” initiative, which was designed to reach building owners and property management firms with fleets of buildings capable of implementing 1 MW of demand savings
– In 2007 alone, these efforts resulted in more than 900 benchmarked buildings
– More at www.pge.com/benchmarking/
• Commonwealth Edison
– Benchmarking support began by providing spreadsheets of energy use data on a regular basis to its customers upon request, which could be used for manual data entry or Upload Template creation.
– Launched in June 2008, ComEd is now offering its commercial customers ABS data feeds for free.
– Today, over 230 building managers are benchmarking more than 560 buildings
