The following are suggestions of how spray foam insulation might be incorporated into a project in order to achieve LEED credits.

• LEED Credit Category – Energy & Atmosphere
  • Prerequisite 2 – Minimum Energy Performance Requires the building to comply with ASHRAE/IESNA Standard 90.1-2004 or the local energy code, whichever is more stringent.  When spray foam is installed into a structure, the insulating and air sealing properties of the foam will provide an envelope that will facilitate the design of an efficient system.
  • Credit 1 – Optimize Energy Performance Requires a reduction in design energy cost compared to the energy cost budget.  When spray foam is installed into your structure, it provides the building with a sealed envelope, allowing the designer to downsize HVAC systems and supply the required ventilation. Spray foam, when used with a whole building concept, can help achieve the 10 possible points.
• LEED Credit Category – Materials & Resources
  • Credit 2 – Construction Waste Management Requires recycling and/or salvaging construction, demolition and land clearing waste.  When BioGreen installs spray foam, exactly what is needed is installed in each area, thereby resulting in very minimal waste. This enables the project reach the 50% to 75% target for diverting waste from the landfill.
  • Credit 6 – Rapidly Renewable Materials Requires use of rapidly renewable products and materials (made from plants harvested within a ten-year cycle or shorter) for 2.5% of the total value of all building materials and products used in the project.  BioGreen uses Demilec Agribalance which is classified as a rapidly renewable product. Depending on the size, cost, and amount of the project insulated, Agribalance can contribute a significant portion of the required 2.5% of rapidly renewable products and materials.  
• LEED Credit Category – Indoor Environmental Quality
  • Credit 4.1 – Low Emitting Materials: Adhesives & Sealants Reduce the concentration of indoor air contaminants that are odorous, irritating and/or harmful to the comfort and well-being of installers and occupants.  BioGreen's spray foam utilizes water as its blowing agent, therefore falls below the 50 VOC g/L less water limit that is set for plastic foams, and can be incorporated into a variety of substrate types and specific applications.
  • Credit 7.1 – Thermal Comfort Requires a thermally comfortable environment and supports the productivity and well being of building occupants.  BioGreen's spray foam can help a building comply with ASHRAE Standard 55-2004 by insulating and air sealing the building, which allows for controlled ventilation strategies that enhance uniform temperatures, humidity control and pollutant reduction.
• LEED Credit Category – Innovation & Design Process
  • Credit 1 – Innovation in Design Provides design teams and projects with an opportunity to be awarded points for exceptional performance above the requirements set by the LEED Green Building Rating System and/or innovative performance in Green Building categories not specifically addressed by the LEED Green Building Rating System.  The superior performance characteristics of BioGreen spray foam and its installation flexibility contribute to this credit in two ways. First, spray foam allows easy installation in areas that do not allow simple installation of conventional insulation products. Second, spray foam is guaranteed to perform to the stated specifications for the life of the structure.
