What is LEED®?

LEED is a rating system that encourages the design and construction of environmentally friendly buildings. Credits are awarded based on five key areas of human and environmental health: sustainable site development, water savings, energy efficiency, materials selection, and indoor environmental quality. For more information, visit the U.S. Green Building Council website: www.usgbc.org.

LEED Credits Rating System (version 2009)

LEED® is a guideline for building solutions established by the USGBC – Products are NOT “LEED certified”, however they can assist in obtaining LEED credit/points for a project.

  • SS Prerequisite 1: Construction Activity Pollution Prevention (Required)

    SSp1 Create and implement an Erosion and Sedimentation Control (ESC) Plan for all construction activities associated with the project.

    CGC United States Gypsum Company erosion and dust control products (AIRTROL® Geobinder, and DUST ARMOUR®) are engineered to provide effective and economical solutions to help our customers achieve their environmental goals. Each of our products incorporates high purity gypsum (calcium sulfate) within the formula. In addition to providing a boost in binding power on even the most difficult terrain, gypsum has a long standing and well documented history of providing soil nutrient and conditioning benefits. Additionally reground drywall from site construction waste can be used as a homemade version of the products listed above and many of the following products to achieve similar goals described. http://www.usg-erosioncontrol.com/environmental/index.asp.

  • SS Credit 3: Brownfield Redevelopment (1 point)

    SSc3 Develop on a site documented as contaminated (by means of an ASTM E1903-97 Phase II Environmental Site Assessment or a local voluntary cleanup program).

    CGC Gypsum can be used to remediate soils polluted with lead, cadmium, aluminum, copper and chromium+6. The calcium in gypsum is soluble and can bind to the metal to form compounds that are insoluble, immobile in soils, and unavailable for uptake by plant tissues. Adding phosphate compounds after gypsum application to the soil converts the essentially insoluble lead sulfate to a totally insoluble compound (pyromorphite). Gypsum can also be used as fill material at brownfield and Superfund sites and, combined with composts, has been used to reclaim abandoned mine lands at affordable prices. http://www.gypsumsolutions.com/

  • SS Credit 9: Tenant Design and Construction Guidelines (1 point)

    SSc9 Publish an illustrated document that provides tenants with the following design and construction information features to serve as an operational and educational manual for the goals and function of this structure and its effect on the surrounding environment and occupants.

    CGC Information provided in this and other ASBE and USG brochures, literature, and websites address many steps taken to reduce footprint and conserve natural resources. Reuse of information, photographs, illustrations, and graphs are allowed for the private use of non-competing personnel and/or companies for the sole purpose of education and/or improvement of the environment.

  • SS Credit 6.2: Stormwater Design: Quantity Control (1 point)

    SSc6.2 Implement a stormwater management plan that reduces impervious cover, promotes infiltration and captures and treats the stormwater runoff from 90% of the average annual rainfall1 using acceptable best management practices (BMPs). BMPs used to treat runoff must be capable of removing 80% of the average annual postdevelopment total suspended solids (TSS) load based on existing monitoring reports.

    CGC United States Gypsum Company erosion and dust control products (AIRTROL® Geobinder, and DUST ARMOUR®) are engineered to provide effective and economical solutions to help our customers achieve their environmental goals. Each of our products incorporates high purity gypsum (calcium sulfate) within the formula. In addition to providing a boost in binding power on even the most difficult terrain, gypsum has a long standing and well documented history of providing soil nutrient and conditioning benefits. In addition, a study Evaluation of Calcium Sulfate for Use in aquaculture Ponds by RUIQUAN WU1 AND CLAUDE E. BOYD of the Department of Fisheries and Allied Aquacultures, Alabama Agricultural Experiment Station Auburn University, Alabama 36849. USA found that gypsum could be used as a pond treatment in aquacuhure for: (1) flocculating clay particles, (2) increasing concentrations of calcium and total hardness, (3) precipitating phosphate, and (4) reducing pH. http://www.usg-erosioncontrol.com/environmental/index.asp

  • SS Credit 6.1: Stormwater Design: Quality Control (1 point)

    SSc6.1 Implement a stormwater management plan that prevents the post-development peak discharge rate and quantity OR protects receiving stream channels from excessive erosion OR that results in a 25% decrease in the volume of stormwater runoff AND that reduces impervious cover, promotes infiltration, and captures and treats the stormwater runoff from 90% of the average annual rainfall using acceptable best management practices (BMPs).

  • WE Credit 1: Water Efficient Landscaping (2-4 points)

    WEc1 Reductions shall be attributed to any combination of the following items: Plant species factor, Irrigation efficiency, Use of captured rainwater, Use of recycled wastewater, and Use of water treated and conveyed by a public agency specifically for non-potable uses OR Install landscaping that does not require permanent irrigation systems. Temporary irrigation systems used for plant establishment are allowed only if removed within one year of installation.

    CGC Gypsum Improves Soil Structure - Gypsum has calcium which is needed to flocculate clays in acid and alkaline soil. Flocculation is the process by which individual clay particles are bound up to give larger particles. This is needed to give favorable soil structure for root growth and air movement within the soil. Gypsum Helps Reclaim Sodic Soils - Gypsum is used in the reclamation of soils by replacing the sodium held on the clay-binding sites. Irrigation using "reclaimed" water from sanitary wastewater systems increases the risks of salinity, sodicity, specific ion toxicity, high alkalinity and heavy metal toxicity. The addition of gypsum either to the reclaimed water or to turf grass soil reduces these risks. Gypsum Holds Water/Reduces Watering Needs - Dr. Wallace from the University of Purdue, Agriculture department found that gypsum-treated soil can have as much as 25% -100% more available water. In summary they found that the use of 1 ton of gypsum per acre per year will reduce watering needs from 20% to 100% depending on crops or plants. The benefits of gypsum and regrind drywall for soil and water improvement are too numeric to list here. For more information visit: http://gypsumsolutions.com/application.asp?app=Agricultural

If only a fraction of a product or material is extracted, harvested, or recovered and manufactured locally, then only that percentage (by weight) can contribute to the regional value.

    CGC USG has more drywall, joint compound, plaster, ceiling tile, ceiling grid manufacturing facilities than any other manufacturer in North America to meet your local needs. For more information on distances of raw materials to our manufacturing facilities of specific USG products refer to the USG Sustainability Tables at www.usg.com or use the LEED Report tool on USG Design Studio (http://www.usgdesignstudio.com/LEEDreport.asp).

  • MR Credit 2: Construction Waste Management (1-2 points)

    MRc2 Recycle, reuse, and/or salvage 50% or 75% (by volume or weight) of any nonhazardous construction, demolition, and land clearing waste.

    CGC The grinding or composting of SHEETROCK® Brand gypsum panel construction waste has been tested by many Agricultural Universities and continues to show benefits of agricultural reuse by local farmers, park districts and home and garden shops as calcium fortification of soils, neutralizing of pH, neutralizing of winter salting, reducing hardness of most soils better than sand or peat, and assists soil in holding nutrients. In addition, the use of one ton of gypsum per acre per year will increase yield and reduce watering needs by 20% to 100%. USG ceiling tiles and grid can often be removed and salvaged for sale at secondary material shops. USG does have a ceiling tile reclamation program for return and remanufacturing into new tiles.

  • MR Credit 1.1: Building Reuse - Maintain Existing Walls, Floor and Roof (1-3 points)

    MRc1.1 Maintain the existing building structure (including structural floor and roof decking) and envelope (the exterior skin and framing, excluding window assemblies and non-structural roofing material).

    CGC USG products are durable and easy to maintain with a long use life allowing them to remain in use during the life of the building without removal and replacement. For information on repair of USG products refer to the Gypsum Construction Handbook which can be found online at www.usg.com.

  • MR Credit 4: Recycled Content (1-2 points)

    MRc4 Use materials with recycled content1 such that the sum of postconsumer2 recycled content plus 1/2 of the preconsumer3 content constitutes at least 10% or 20%, based on cost, of the total value of the materials in the project.

    CGC USG products are high in recycled content, while maintaining a high durability index or life expectancy. USG currently uses more recaptured, post-industrial gypsum produced by flue-gas desulfurization (FGD) processes at North American coal-fired utility plants than does any other manufacturer. This "recaptured gypsum" represents approximately 33 per-cent of the raw gypsum material used by USG in 2008 to manufacture drywall, plaster, and ceiling panel products. FGD-produced recaptured gypsum is delivered to our plants in powder form, thus reducing mining and grinding of natural gypsum rock. It accounts for approximately ten percent of our drywall products' embodied energy rating. With the long life and durability of drywall and the numerous benefits of reuse such as agricultural, the potential industry average for post-consumer content is in the range of 4% to 20%. For more information on the recycled content of specific USG products refer to the USG Sustainability Tables (http://usg.com/USG_Marketing_Content/usg.com/web_files/Documents/A56_Sustainability_tables.pdf).
