  • Reduce greenhouse gas (GHG) emissions through large win-win-win opportunities with today’s energy efficient technologies and practices

    • 30% savings in many buildings, homes, and facilities

  • Provide credible information to buyers to

    • reduce transaction (research) costs

    • reduce perceptions of risk

    • enhance investment in efficient technologies and practices

  • Work with the marketplace to build on motivations of important individual actors

Broad Strategies

ResidentialCommercial / Industrial

Labeled Products Corporate energy management

-- 40+ products / 1400 manufacturers -- benchmarking, goals, upgrades

-- 10-60% more efficient (management, systems more than widgets)

Labeled New Homes -- whole building labeling forexcellence

-- 30% more efficient

Home Improvement Labeled Products

Services -- for plug loads -- not system components

-- beyond products

-- ducts / home sealing Small business initiative

-- whole home retrofits

Success to date l.jpg
Success to date

  • Started in 1992; now the government backed symbol for energy efficiency

  • In 2005, Americans, with help of ENERGY STAR:

    • saved $12 billion on energy bills

    • prevented ghg emissions equal to 23 million cars

  • ENERGY STAR recognized by over 60% of Americans

  • To date l.jpg
    To date

    • More than 1.5 billion ENERGY STAR products have been sold to date.

    • More than 2,500 builders have constructed over 360,000 ENERGY STAR homes.

    • EPA’s Energy Performance Rating System has been used to evaluate more than 21,000 buildings; 20% of office buildings, 13% percent of schools, 21% of supermarkets, 34% of hospitals, 9% of hotels have been benchmarked.

    • More than 2,000 buildings have earned the ENERGY STAR.

    Commercial building opportunities l.jpg
    Commercial Building Opportunities

    • Many cost-effective improvements

      • efficient building uses 40% less than average buildings

      • paybacks of less than 3 to 5 years

    • Focus on: Whole Building Performance

      • promote integration of systems

      • about energy savings -- not presence of new technology

      • achieve twice the savings for a given investment

    • Performance Measurement System

      • can not manage what you can not measure

      • fix missing market information

        • how to measure efficiency / performance

        • when is a building efficient

      • provide information linked to real market transactions (like energy bills)

    Energy star challenge l.jpg
    ENERGY STAR Challenge

    • National campaign focused on building energy efficiency– promote 10%, 20%, 30% improvements and strategic energy management

    • Launched in March 2005

    • Now supported by ~50 leading associations and states across all sectors (more than half of US states)

    • Creating national call to action to reduce energy use in all building sectors:

      • K-12 Schools

      • Higher Education

      • State and Local Government

      • Commercial and Corporate Real Estate

      • Healthcare

    A changing landscape increases importance of energy efficiency l.jpg
    A Changing Landscape IncreasesImportance of Energy Efficiency

    • Energy consumption and costs are rising

    • Market volatility is increasing risk and uncertainty

    • Managing the risk of climate change is becoming a reality for many organizations.

    • Trend toward green building is not necessarily leading to energy-efficient buildings

    • Taxpayers benefits from cost-effective reductions:

    • ENERGY STAR qualified offices demonstrate:

      • 35% less energy use

      • $0.50 per square foot less to operate

      • Energy performance persists over multiple years

      • Designing to earn ENERGY STAR helps high performance green buildings stay within conventional construction budget

    Energy s role in green building l.jpg
    Energy’s Role in Green Building

    • Energy efficiency should be foundation for green building

    • Market assumes green buildings are energy efficient

      • Studies now show that this is not necessarily the case

    • ROI for green buildings comes largely from energy

    • Large environmental benefits from reducing greenhouse gas and other air emissions.

    • Can’t rely solely on technology and code requirements for energy performance

      • Problem:

        • “Better than code” is only weakly correlated to energy performance

        • Specific technologies do not guarantee energy performance

    Energy performance gap

    • Normalized EUI for existing office buildings varies widely

    • 30 kbtu/ft2 to 340 kBtu/ft2

    • Age and equipment not significant drivers of EUI

    Simple energy metric14 l.jpg
    Simple Energy Metric

    • Normalize Building Energy Consumption from bills

      • Weather, hours, occupant density, plug load

      • Whole-building “mpg” rating

    • Compare

      • Benchmark against similar buildings in national stock

      • Receive 1-100 score

    • Reward:

      • Buildings in top 25% qualify for the ENERGY STAR

      • Buildings with intent to perform in top 25% designated “Designed to Earn ENERGY STAR.

      • Organizations with portfolio improvement 10, 20, and 30 point qualify as ENERGY STAR Leader

    If it’s not energy efficient …

    …it’s not on a sustainable path.
