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.

6
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.

7
Federal Buildings

• Federal Govt 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.

8
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 EPAs energy performance rating

10
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

11
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,

12
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.

13
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.
