9 LEED LEED® Awareness LEED Certification Levels LEED and the EHS ProfessionalLEED Certification LevelsThere are 4 levels of LEED certification:Certified 40 – 49 pointsSilver 50 – 59 pointsGold 60 – 79 pointsPlatinum 80 – 110 points
10 LEED 2009 LEED® Awareness LEED 2009 LEED and the EHS Professional Each credit is allocated points based on the relative importance of the building related impacts it addressesImpacts 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 conditionsLEED 2009 uses the EPA’s TRACI environmental impact categories for weighing each creditTRACI was developed to assist with impact evaluation with life cycle assessment, industrial ecology, process design and pollution prevention.
