        ENERGY STAR


In 2005, Americans with the
help of ENERGY STAR,
prevented 35 million metric tons
of greenhouse gas emissions
and saved about $12 billion on
their utility bills.
ENERGY STAR Challenge Impact

• Our governments, schools, and businesses
  spend billions annually on energy. Typically,
  about 1/3 of this money is paid to utility
  companies unnecessarily due to energy
  inefficiency.
• Instead, this money could be invested in energy
  efficiency which can improve the lighting,
  acoustics, thermal comfort, and indoor air quality
  creating a better working and learning
  environment.
           Federal Buildings

• Federal Gov’t owns about 445,000
  buildings with more than 3 billion square
  feet
• If these buildings reduced energy use
  by 10%, in 10 years taxpayers would
  save $420 million and reduce ghg
  equivalent to those from 625,000 cars.
  Sustainable Building Principles

Federal MOU
• Signed by GSA, DOD, EPA, and many others at White House Summit
• Includes the following:
   – Integrated Design & Commissioning
   – Optimize Energy Performance
   – Water Efficiency – Use 20% less than potable water than indoor use
      baseline & reduce outdoor potable water consumption by 50%.
   – Indoor Environmental Quality –
        • ASHRAE 2004 ventilation and for thermal comfort
        • Establish moisture control strategy
        • Daylighting – achieve min of 2% daylighting factor in 75percent of
          space
        • Low-Emitting Material adhesives, sealants, paints, carpet
          systems, and furninshings
        • Protect indoor environment during construction
   – Reduce Environmental Impact of Materials – recycled content,
      biobased content, construction waste, ozone depleting compounds.
New Model for Achieving Green and
       Energy Efficiency

• Guiding Principles for Federal Leadership in
  High Performance and Sustainable Buildings
  focus on performance:
   – Establish whole building performance target:
      • Design to Earn ENERGY STAR
   – Reduce energy cost budget 30% from ASHRAE
     90.1-2004
      • Increase efficiency of components
   – Measure and verify energy use
      • Compare to design target
      • Use EPA’s energy performance rating
 Why Use ENERGY STAR?

A high performance/green building can:
• Cost the same or less to build
• Cost less to operate
• Helps protect the environment
  – Reduces greenhouse gas emissions
    and air pollution from burning fossil
    fuels to generate energy to run
    buildings
How can you build a High Performance/green
building cost-effectively?

Strive to build High Performance/Green
  Buildings while paying special attention to:
• Building orientation and the use of daylighting
  in the building design,
• Energy-efficient building envelope and
  windows,
• Use correctly sized energy-efficient
  technologies,
How can you build a High Performance/green
building cost-effectively?

Continued
• Use cost-effective on-site renewable energy –
  (wind, geothermal, other),
• Use interior materials, furnishings, and cleaning
  practices that minimize indoor air pollutants, and
• Design to control space humidity
• Commissioning equipment to perform as
  intended and use zones.
     Cost Trading Principle


Using daylighting and an energy-
efficient building envelope with high
efficiency windows can reduce the
amount, size, and capital costs of the
equipment used to provide artificial
lighting, heating and cooling
equipment.
