LEED v3: ICFs & Energy and Atmosphere
August 11th, 2009 | Lets Get Technical!
Energy and Atmosphere (EA): This LEED topic covers measures to improve the energy efficiency and reductions in use of ozone depleting refrigerants and green house gases. If you give thought to your building envelope and design with Reward ICFs, it can be incredibly easier to achieve up to the maximum 21 point value.
Building the exterior walls with Reward ICFs contributes to this requirement and credit by providing superior air tightness, insulating value and thermal massing. Use of Reward Wall Systems will result in a better insulated, energy efficient exterior wall system. The continuous solid insulated concrete wall created by Reward will reduce air infiltration and provide thermal mass benefits.

Combined with other components like energy efficient glazing and window units, well insulated roof assemblies, and design strategies like effective solar orientation, Reward can contribute to a project qualifying for minimum energy performance under EA Prerequisite 2, and for additional credits for energy performance beyond the minimum ASHRAE energy code requirements, under the Optimized Energy Performance credit.

EA Prerequisite 2: Reward can contribute to the required prerequisite compliance with meeting the minimum performance standards of ASHRAE 90.1-2007 energy code
Credit is obtained for performance improvements beyond the minimum ASRAE 90.1 energy code requirements (up to 19 points).
