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 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.
