Use this summary of key points and information about ENERGY STAR*, the Challenge, and commercial and industrial
buildings to help make your Challenge communications more informative.

What Is ENERGY STAR?
>   ENERGY STAR is best known as a label for products, such as appliances, that meet strict energy efficiency guidelines set by the
    U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE). But the ENERGY STAR also identifies superior
    energy performance for America's commercial and industrial buildings.
>   Whether a school, hospital, small business, or large corporation, ENERGY STAR can help reduce energy use, save money, and help
    protect the environment.


The ENERGY STAR Challenge
>   Whetheryou're associated with a small school or a large corporation, a  local government or a national association, a community
    hospital or a hotel group, a manufacturing planter a retailer — you can be part of the ENERGY STAR Challenge and  help improve
    the efficiency of America's commercial and industrial buildings by 10 percent or more.
>   EPA estimates that if the energy efficiency of commercial and industrial  buildings improved by 10 percent, Americans would save
    about $20 billion and reduce greenhouse  gas emissions equal to the emissions from almost 30 million vehicles.1
>   Challenge participants and their members are encouraged to:
            •   Measure and track energy use.
            •   Develop a plan for energy improvements.
            •   Make energy efficiency upgrades.
            •   Help spread the energy efficiency word to others.


Buildings, Energy, and Greenhouse Gas Emissions
>   The energy used in homes and commercial  buildings is often generated by burning fossil fuels, which emit greenhouse  gases that
    contribute to climate change.
>   Making  more efficient use of energy is the best starting point for addressing climate change, particularly because there is the
    potential for immediate financial payoff along with long-term environmental benefits.
>   The buildings in which we work, shop, play, and educate our children use about $200 billion worth of electricity and  natural gas
    each year.2
>   Commercial and industrial buildings in the U.S. contribute 45 percent of our national emissions of greenhouse gases.3
>   Over the next 25 years, greenhouse gas emissions from buildings are projected to grow faster than any other sector, with emissions
    from commercial buildings leading the way — a projected 1.8 percent a year through 2030.4

Buildings, Energy, and Greenhouse Gas Emissions (cont'd)
>   By reducing greenhouse gas emissions through improved energy efficiency, businesses save money, improve productivity, protect
    the environment, and increase the nation's energy security.
>   Many of us are taking steps to improve energy efficiency at home, but may not realize that there are opportunities to save at work
    as well. By making energy-efficient choices at work, Americans can help businesses reduce energy use and save money while
    preventing climate change.


Energy Efficiency Is Smart Business
>   Today, leading companies realize that energy efficiency is not just a bout smart business or the first step to being green. Instead, they
    realize that it can have a high return-on-investment and is necessary in order to remain competitive.
>   Businesses and organizations that are leaders in energy efficiency use about 30 percent less energy than their competitors.
>   Over the last 30 years, energy efficiency has reduced our country's energy use by 47 percent and is our greatest energy "resource."5
>   Businesses across the economy are saving energy and experiencing remarkable financial results with the help of ENERGY STAR:
           •   ENERGY STAR buildings' utility bills are over 50 cents per square foot less than average buildings', and over $2 less per
              square foot.
           •   On average, ENERGY STAR buildings use 35 percent less energy than average buildings.
           •   Full-service hotels that improve energy efficiency by 10  percent see savings equal to an increased average daily rate of $1.35.
           •   By reducing energy costs by just 5 percent, for-profit hospitals can increase earnings by one penny per share.
>   ENERGY STAR offers a clear performance advantage:
           •   Nearly 30 percent of Fortune 500 companies are ENERGY STAR partners.
           •  As of the end of 2006, more than 3,200 buildings across the country had earned the ENERGY STAR.
           •   ENERGY STAR office properties gross higher rents and higher occupancy rates than their non-ENERGY STAR counterparts.6


Green Isn't Green Without Energy Efficiency
>   Although a building can have a wide variety of environmentally friendly features, a building is not truly green unless it is
    energy efficient.
>   Energy efficiency is the single largest wayfor a building to reduce its "carbon footprint."
>   For assurance that a building is both energy  efficient and environmentally sustainable, look for the ENERGY STAR and green building
    certification together.


ENERGY STAR Is the Solution
>   ENERGY STAR provides the tools and resources to help businesses and organizations identify areas for improving energy efficiency
    and develop a strategic energy management plan. ENERGY STAR offers:
           •  A national performance rating system for buildings to benchmark and track energy performance.
           •  Guidance for designing  energy-efficient buildings.
           •  Advice for developing effective organizational energy management programs.
           •   Case  studies and best practices from leading public and private-sector organizations.
           •   Calculators to estimate returns on energy efficiency investments.
           •   Materials to communicate with employees, stakeholders, the media, and  other interested parties about energy improvements
               and benefits to the bottom line and the environment.
