LEED Documentation
Applicable LEED Credits:
Energy & Atmosphere (EA) Prerequisite 2 – Minimum Energy Performance
Establish the minimum level of energy efficiency for the proposed building and systems to reduce environmental and economic impacts associated with excessive energy use.
Energy & Atmosphere (EA) Credit 1 – Optimize Energy Performance
Achieve increasing levels of energy performance beyond the prerequisite standard to reduce environmental and economic impacts associated with excessive energy use.
Materials & Resources (MR) Credit 1.2 – Building Reuse – Maintain Existing Interior Non-Structural Elements
Extend the lifecycle of existing building stock, conserve resources, retain cultural resources, reduce waste and reduce environmental impacts of new buildings as they relate to materials manufacturing and transport.
Materials & Resources (MR) Credit 4 – Recycled Content
Increase demand for building products that incorporate recycled content materials, thereby reducing impacts resulting from extraction and processing of virgin materials. Use materials with recycled content such that the sum of post-consumer recycled content plus 1/2 of the pre-consumer content constitutes at least 10% or 20%, based on cost, of the total value of the materials in the project. The recycled content value of a material assembly is determined by weight. The recycled fraction of the assembly is then multiplied by the cost of assembly to determine the recycled content value.
Materials & Resources (MR) Credit 5 – Regional Material
Increase demand for building materials and products that are extracted and manufactured within the region, thereby supporting the use of indigenous resources and reducing the environmental impacts resulting from transportation. Use building materials or products that have been extracted, harvested or recovered, as well as manufactured, within 500 miles of the project site for a minimum of 10% or 20%, based on cost, of the total materials value.
Materials & Resources (MR) Credit 6 – Rapidly Renewable Materials
Reduce the use and depletion of finite raw materials and long-cycle renewable materials by replacing them with rapidly renewable materials. Use rapidly renewable building materials and products for 2.5% of the total value of all building materials and products used in the project, based on cost. Rapidly renewable building materials and products are made from plants that are typically harvested within a 10-year or shorter cycle.
Materials & Resources (MR) Credit 7 – Certified Wood
Encourage environmentally responsible forest management. Use a minimum of 50% (based on cost) of wood-based materials and products that are certified in accordance with the Forest Stewardship Council’s® (FSC) principles and criteria, for wood building components. These components include at a minimum, structural framing, and general dimensional framing, flooring, sub-flooring, wood doors and finishes.
Indoor Environmental Quality (IEQ) Prerequisite 2 – Tobacco Smoke Control
Prevent or minimize exposure of building occupants, indoor surfaces and ventilation air distribution systems to environmental tobacco smoke (ETS). Weather-strip all doors in the residential units leading to common hallways to minimize air leakage into the hallway.
Indoor Environmental Quality (IEQ) Credit 4.1 & 4.2 – Low-Emitting Materials: Adhesives & Sealants, Paints & Coatings
Reduce the number of indoor air contaminants that are odorous, irritating and/or harmful to the comfort and well-being of installers and occupants. This credit only applies to materials applied within the weatherproofing system.
Indoor Environmental Quality (IEQ) Credit 4.4 – Low-Emitting Materials: Composite Wood & Agrifiber Products
Reduce the number of indoor air contaminants that are odorous, irritating and/or harmful to the comfort and well-being of installers and occupants. Composite wood and agrifiber products used on the interior of the building (i.e., inside of the weatherproofing system) must contain no added urea-formaldehyde (NAUF) resins.
Indoor Environmental Quality (IEQ) Credit 5 – Indoor Chemical & Pollutant Source Control
Minimize building occupant exposure to potentially hazardous particulates and chemical pollutants. Sufficiently exhaust each space where hazardous gases or chemicals may be present or used (e.g., garages, housekeeping and laundry areas, copying and printing rooms) to create negative pressure with respect to adjacent spaces when the doors to the room are closed. For each of these spaces, provide self-closing doors and deck-to-deck partitions or a hard-lid ceiling. Door closers and gasketing should be specified on all openings where hazardous particulates and chemical pollutants may be present.
Indoor Environmental Quality (IEQ) Credit 8.1 & 8.2 – Daylights & Views
Provide building occupants with a connection between indoor spaces and the outdoors through the introduction of daylight and views into the regularly occupied areas of the building.
LEED for Schools Specific Credits
Indoor Environmental Quality (IEQ) Credit 9- Enhanced Acoustical Performance
Provide classrooms that facilitate better teacher-to-student and student-to-student communications through effective acoustical design. Design the building shell, classroom partitions and other core learning space partitions to meet the Sound Transmission Class (STC) requirements of ANSI Standard S12.60-2002, Acoustical Performance Criteria, Design Requirements and Guidelines for Schools, except windows, which must meet an STC rating of at least 35.
Indoor Environmental Quality (IEQ) Credit 10 – Mold Prevention
Reduce the potential presence of mold in schools through preventive design and construction measures.
LEED EBOM Specific Credits
Materials & Resources Credit 3 – Sustainable Purchasing: Facility Alterations & Additions
Reduce the environmental and air quality impacts of the materials acquired for use in the upgrade of buildings. Maintain a sustainable purchasing program covering materials for facility renovations, demolitions, refits and new construction additions.
Materials & Resources Credit 9 – Solid Waste Management: Facility Alterations & Additions
Divert construction and demolition debris from disposal to landfills and incineration facilities. Redirect recyclable recovered resources back to the manufacturing process and reusable materials to appropriate sites.
