LEED Rating System Overview
Defining “Green” and Sustainability
AgendaLEED and the EHS Professional
USGBC – an organization
LEED – a rating system
Projects are certified.
Individuals are accredited.
DefinitionsLEED and the EHS Professional
U.S. Green Building Council Formed in 1993 National 501(c)(3) nonprofit organization Organization that certifies sustainable construction:
businesses, homes, hospitals, schools, and neighborhoods
Dedicated to expanding green building practices and education
Developer of the LEED® Green Building Rating System™
The USGBCLEED and the EHS Professional
LEED ® – Leadership in Energy and Environmental Design
One of the nationally accepted benchmarks for the design, construction and operation of high performance green buildings
LEED® AwarenessLEEDLEED and the EHS Professional
Define and measure “green buildings”
Facilitiate positive results for the environment, occupant health and financial return
Prevent “greenwashing” (false or exaggerated claims)
Promote whole building, integrated design processes
LEED® Awareness
Why LEED Was Created
LEEDLEED and the EHS Professional
LEED® Awareness
In the United States, buildings account for:
36% of total energy use
65% of electricity consumption
30% of greenhouse gas emissions
30% of raw materials use
30% of waste output - 136 million tons annually!
12% of potable water consumption

Environmental Impact of Buildings
LEEDLEED and the EHS Professional
EnvironmentalImprove air and water quality
Reduce solid waste
Conserve natural resources and ecosystems
Health and CommunityMinimize strain on local infrastructure
Contribute to overall quality of life
Improve employee health and productivity
Benefits of Green Building
LEEDLEED and the EHS Professional
There are 4 levels of LEED certification:
Certified 40 – 49 pointsSilver 50 – 59 pointsGold 60 – 79 pointsPlatinum 80 – 110 points
LEED® Awareness
LEED Certification Levels
LEEDLEED and the EHS Professional
Each credit is allocated points based on the relative importance of
the building related impacts it addresses
Impacts are defined as the environmental or human impact of the design, construction, operation and maintenance of the building, such as greenhouse gas emissions, fossil fuel use, toxins and carcinogens, air and water pollutants, and indoor environmental conditions
LEED 2009 uses the EPA’s TRACI environmental impact categories for weighing each credit
TRACI was developed to assist with impact evaluation with life cycle assessment, industrial ecology, process design and pollution prevention.

LEED RATING SYSTEMSLEED and the EHS Professional
Prerequisites vs. Credits
A prerequisite must be met – no points are given
A credit is elective, but a project must earn enough credits to achieve the desired certification level.
