1 LEED and the EHS Professional

2 Agenda Introductions Definitions USGBC and LEED LEED Rating System Overview Defining Green and Sustainability Agenda LEED and the EHS Professional

3 USGBC – an organization LEED – a rating system Projects are certified. Individuals are accredited. Definitions LEED and the EHS Professional

4 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 USGBC LEED and the EHS Professional

5 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 ® Awareness LEED LEED and the EHS Professional

6 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 LEED LEED and the EHS Professional

7 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 million tons annually! 12% of potable water consumption SOURCE: USGBC Environmental Impact of Buildings LEED LEED and the EHS Professional

8 Environmental Improve air and water quality Reduce solid waste Conserve natural resources and ecosystems Health and Community Minimize strain on local infrastructure Contribute to overall quality of life Improve employee health and productivity Benefits of Green Building LEED LEED and the EHS Professional

9 There are 4 levels of LEED certification: Certified40 – 49 points Silver 50 – 59 points Gold 60 – 79 points Platinum 80 – 110 points LEED ® Awareness LEED Certification Levels LEED LEED and the EHS Professional

10 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 EPAs 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 ® Awareness LEED 2009 LEED and the EHS Professional

11 LEED RATING SYSTEMS LEED and the EHS Professional

12 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. LEED ® Rating Systems LEED Rating Systems LEED and the EHS Professional
