1. Sustainable Sites (SS)
BY USING PERMEABLE CONCRETE or brick masonry pavements or open cell concrete masonry pavers, masonry can contribute up to three points in this category.
Credit 6.1: Stormwater Management - Rate and Quantity
The intent of this credit is to limit disruption and pollution of natural water flows by managing or eliminating stormwater runoff, increasing on-site infiltration and eliminating contaminants. One point is awarded if, for a site with an existing imperviousness less than or equal to 50%, the post-development 1.5 year, 24-hour peak discharge rate does not exceed the pre-development rate; or if, for a site with an existing imperviousness greater than 50%, the rate and quantity of stormwater runoff is decreased by 25%.
Credit 6.2: Stormwater Management - Treatment
The intent of this credit is the same as for Credit 6.1. One point is awarded for stormwater treatment systems designed to remove 80% of the average annual post-development total suspended solids (TSS) and 40% of the average annual post-development total phosphorous (TP). Recommended best

GREENBUILD 2004
Green building has become a major force in building and construction. With adoptions by major building owners including GSA, Toyota, PNC Financial Services Group and many others, it's fast becoming recognized as the standard for smart construction.
The U.S. Green Building Council's Greenbuild International Conference & Expo brings the industry together under one roof. Three days of extensive educational programming, a vast exhibition floor including over 400 product and service displays, and ample networking events give you unrivaled opportunities to learn about the latest innovations, exchange ideas and develop new business relationships.
Last year's conference drew more than 5,200 professionals from 22 countries, including architects and engineers, facilities managers, developers, contractors, builders, interior designers, federal, state and local governments, and product manufacturers, just to name a few.
Join us in Portland, Ore., Nov. 10-12, 2004, to learn about the leading edge of the building and construction industry, including the latest updates and expansions of the LEED Green Building Rating System. For years you've been building upward. At Greenbuild, learn how to build forward.

management practices for achieving this credit include the use of porous pavements.
Credit 7.1: Heat Island Effect - Non-Roof
The intent of this credit is to reduce heat islands to minimize impact on microclimate and human and wildlife habitat. One point is awarded if shade and/or light-colored/high-albedo materials and/or open-grid pavement are provided for at least 30% of the site's non-roof impervious surfaces. Or one point can be awarded for the use of an open-grid pavement system (less than 50% impervious) for a minimum of 50% of the parking lot area.
3. Energy and Atmosphere (EA)
MASONRY CAN CONTRIBUTE to achieving points in this category by harvesting site energy (using passive solar designs) and decreasing the size of the building HVAC system. The thermal mass inherent in masonry reduces temperature swings, stores heat/cooling for release at later times, and reduces peak energy loads. These strategies can reduce the size of the HVAC system required.
