Also from May, GBCI will phase in new examination and qualification maintenance requirements for LEED Accredited Professionals that distinguish those who maintain their knowledge and skill to successfully steward the certification process. Summary of major changes to LEED NC credit requirements • SSc2 Development Density and Community Connectivity Stricter requirements for the 10 basic services • SS4.1 Public Transportation Access Rail and bus stops measured by walking distance • SSc4.3 Low Emitting and Fuel Efficient Vehicles Stricter requirements for discounted parking rates and car sharing • SSc8 Light Pollution Reduction Stricter control of non-emergency lighting outside working hours • WEp1 Water Use Reduction 20% reduction is now a prerequisite • WEc1 Water Efficient Landscaping Potable water saving linked to overall water use reduction • WEc3 Water Use Reduction Savings thresholds now 30, 35 and 40% • EAp2 Minimum Energy Performance Savings threshold reduced from 14% to 10% below baseline • EAc5 Measurement and Verification Corrective action required if predicted energy saving is not realised • MRc1 Building Reuse – Existing Walls, Floors and Roof Minimum threshold reduced to 55% • EQc4.3 Low Emitting Materials: Flooring Systems Previously addressed carpet systems only • EQc5 Indoor Chemical and Pollutant Source Control Length of permanent entryway systems increased; new requirements for hazardous liquid waste containment • EQc8.1 Daylight and Views New methods of calculating daylight TRACI is a software program developed by the US EPA to assist with impact assessment for sustainability metrics, life cycle costs, industrial ecology, process design, and pollution prevention. The categories of environmental impact incorporated into LEED 2009 and their relative weights devised by NIST are: • Greenhouse Gas Emissions (29%) • Fossil Fuel Depletion (10%) • Water Use (8%) • Land Use (6%) • Acidification (3%) • Eutrophication (6%) • Ozone Depletion (2%) • Smog Formation (4%) • Ecotoxicity (7%) • Particulates (9%) • Human Health–Cancer (8%) • Human Health–Non-Cancer (5%) • Indoor Environmental Quality (3%) 1.
