US EPASeptember 2009
What is ENERGY STAR?
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.
ENERGY STAR
What is ENERGY STAR forCommercial 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
Opportunities in Buildings
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.
K-12 Schools and ENERGY STAR
• 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% district-wide
– More than 16,000 K-12 school facilities have been benchmarked in ENERGY STAR Portfolio Manager
6www.energystar.gov/k-12
• Located in Pennsylvania• Across the district’s 17 facilities
– More than 6,000 tons of CO2 emissions have been avoided
– Electricity use has been reduced by 7.7 million kilowatt hours– More than $2.5 million saved in just 2 years

Key Steps:
- Develop tracking, evaluation, and reporting plan
- Establish baselines
- Conduct benchmarking
- Track energy use, emissions, and savings
- Estimate impacts
- Report progress
- Revise program based on results, as appropriate

ENERGY STAR Portfolio Manager
• Free on-line benchmarking tool for all commercial buildings
• Track energy use – Weather normalized source EUI– National average comparisons – Comparison to custom baselines– Energy performance ratings (for selected spaces)
• Track energy costs, upgrades, and investment cost• Track carbon emissions • Track water consumption• Customized dashboard and data sharing• Apply for ENERGY STAR recognition
Assess Performance for Strategic Energy Management
1. Identify best opportunities for savings2. Track progress over time3. 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 ManagerFour Simple Steps
1. Create/edit a Portfolio Manager account2. Add/edit a property3. Add/edit a space4. Add/edit energy meters
Address• Zip Code for weather normalization
Energy Consumption• 12 consecutive months for each source
Space Type Data• Square footage• High School (Y/N)• Open On Weekends (Y/N)• Number of Walk-in Refrigeration Units• Number of Months in Operation (Optional)• Number of Personal Computers• Percent of Floor Area Heated and Cooled• Presence of On-Site Cooking Facilities
Data for K-12 Schools
Automated Data Options: ABS
• Utilities can provide energy data directly into Portfolio Manager
• Energy Services Companies can host data from Portfolio Manager in their own software for customers
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
