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 energyefficient 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.
