Leadership in Energy and Environmental Design
LEED is a third-party certification
program and the nationally
accepted benchmark for the
design, construction and
operation of high performance
green buildings.
LEED promotes a whole-building
approach to sustainability by
recognizing performance in five key
areas of human and environmental
health: sustainable site development,
water savings, energy efficiency,
materials selection and indoor
environmental quality.

Sustainable Sites
•
•
•
•
•
•
Develop appropriate sites
Use existing infrastructure
Preserve natural areas
Reduce need for automobiles
Protect endangered habitats
Restore polluted sites
12
Water Efficiency
•In the U.S., about 340 billion gallons
of fresh water are withdrawn daily
from rivers, streams, & reservoirs
•Water treatment is municipality’s
single biggest energy bill
(water savings = energy savings)
•Power plants consume 3 gallons of
water per kWh produced (energy
savings = water savings)
13
Energy & Atmosphere
• Buildings consume ~40% of U.S. energy (70% of electricity)
• Fossil fuels produce 3/4 of our energy
• Coal power plants emit more fine particulate material
than any other U.S. activity
• Natural gas (CO2), nuclear energy (radiation), and
hydroelectric power (habitat disturbance) all have negative
impacts on ecological systems
• Efficient buildings reduce pollution & cost and enhance
comfort
17 possible points
14
Materials &
Resources
•Construction/Demolition waste
makes up 40% of U.S. waste
•Reuse/Recycling saves
production & transportation
energy & landfill room
•Salvaged/Recycled content
materials minimize the use of
finite, declining resources
•Rapidly Renewable resources
minimize impact of natural
resource consumption for
manufacturing
15
Indoor Environmental Quality
•Americans spend 90% of their time
indoors
•Inside pollutant levels may be 2 to 5
times higher than outdoor levels
•17 million Americans have asthma and
40 million suffer from allergies
•Better IEQ can improve worker
productivity more than 15%
15 possible points
