The LEED certification program, originally developed by the U.S. Green Building Council, is one of the most popular and widely recognized green building certification programs. The program is also available in Canada.
The LEED for Homes program was established in 2008 and measures green homebuilding performance based on eight categories. Categories include: Sustainable Sites, Water Efficiency, Materials & Resources, Energy & Atmosphere, Indoor Environmental Quality, Location & Linkages, Awareness & Education, Innovation and Design Process. Insulation, specifically spray foam insulation, can contribute to credit towards achieving LEED certification. Below are six categories where spray foam insulation like Icynene can contribute to LEED certification.
- Optimizing Energy Performance (EA 1.1) – The use of spray foam could help meet the performance requirement of an ENERGY STAR-labelled home in this prerequisite category.
- Exceptional Energy Performance (EA 1.2) – Spray foam like Icynene can contribute up to 5 points in this category due to energy savings of up to 12.3% being achieved with spray foam insulation products versus traditional options.
- Insulation (EA 2) – By offering high R-values and by greatly simplifying the effort required to achieve HERS Grade 1 workmanship, foam insulation can contribute two points in this category.
- Air Infiltration (EA 3) – Foam insulation can significantly reduce building envelope air leakage of less than or equal to the required ACH @ 50 Pa. A total of three points can be gained in this category.
- Environmentally Preferable Products (MR2) – Icynene spray foam insulation products are Collaborative for High Performance Schools (CHPS) EQ 2.2 Section 01350 compliant. This means that they meet nationally recognized requirements as a low-emitting material in accordance with the California Department of Health Services Standard Practice.
- Recycled Content (MR4) - The 3.4% by weight of recycled content (normalized by adjusting for pre-consumer versus postconsumer) of Icynene ProSeal and Icynene ProSeal Eco product can contribute towards the 10-20% of building material, based on cost, required to be made of recycled material.
Beyond contributing to LEED certification, there are additional performance and design advantages that spray foam insulation like Icynene can offer architects and builders. Working with Icynene’s building science team can help architects and designers realize the true potential of their projects.
