WHAT IS LEED VERSION 4?
LEED V4 is the latest version of the LEED green building certification system approved by voters in July 2013. V4 is currently undergoing pilot testing and will be officially launched at Greenbuild in November 2013. LEED 2009 (V3) may be used until June 2015 when it will be phased out of existence.
Sika Sarnafil’s EnergySmart Roof® membranes and Green Roof systems can contribute to multiple points in LEED’s Sustainable Sites category. This is done by replacing natural landscape removed in the construction process with a green (vegetated) roof, encouraging regionally appropriate landscaping, controlling stormwater runoff; and helping reduce the heat island effect. Below are the sections where Sika Sarnafil products can help you obtain points towards LEED certification:
Protect or Restore Habitat
|A Green "vegetated" Roof contributes to the possible 2 points.|
Maximize Open Space
A Green "vegetated" Roof contributes to the possible 1 points.
|Rainwater Managementl||A Green "vegtetated" Roof contributes to the 3 points.|
|Heat Island Reduction||
An EnergySmart Roof or a Green "vegetated" Roof can obtain up to 2 points.
Places of Respite
||Installing a Green "vegetated" Roof contributes to the attainment of 1 point.|
Energy & Atmosphere
Sika Sarnafil’s EnergySmart Roof membranes, Sarnatherm Insulation and Solar Roof systems can contribute to multiple points in LEED’s Energy & Atmosphere category. This is accomplished by helping optimize energy performance and the use of renewable and clean sources of energy, generated on-site. Below are the sections where Sika Sarnafil products can help you achieve points towards LEED certification:
|Energy and Atmosphere Credit (Renewable Energy Production)||A Solar Roof can reduce the need for fossile fuel energy use contributing to the possible 3 points|
Materials and Resources
Sika Sarnafil’s EnergySmart Roof membranes and Roof Recycling Program can be used to obtain multiple points in LEED’s Materials and Resources category. A mechanically attached vinyl roof at the end of its useful life can be recycled by Sika Sarnafil into new roofing membrane products and replaced with a roof membrane that is made with pre- and post-consumer recycled waste. Below are the sections where Sika Sarnafil can help with points towards LEED certification:
|Environmental Product Declarations||
The Roofing Industry is pursuing a Generic PVC roofing EPD which will contribute to the attainment of 1/4 to 1/2 point. Separately, Sika Roofing will pursue a product specific Type III EPD that will contribute to the attainment of 1 full point.
|Sourcing of Raw Materials||Sika Sarnafil's S327 and G410 (5' and 10' model), Sikplan, PVC Protection Layer and Sarnatred collectively contain an average of 10% recycled content and can contribute to the attainment of 1 point under this credit.|
|Material Ingredients||Sika roofing systems do not contain any substances that meet REACH criteria for substances of very high concern and therefore can contribute toward the attainment of 1 point. We are in the process of determining the verification procedure and will communicate when available.|
|Materials and Resources Credit: Construction and Demolition Waste Management||Sika Roof Recycling Program contributes to the possible 2 points (one point is for Exemplary Performance under the Innovation in Design Credits Section).|
Sika roofing's Low or No VOC emitting roof membrane adhesives and stone wool insulation can be used to obtain multiple points in LEED’s Environmental Quality category. This is accomplished by not contributing to possible fumes and/or odors during building construction. Below is the section where Sika Sarnafil products can help you achieve LEED points:
|Minimum Acoustic Performance||Sika roofing systems with Roxul stone wool insulation will contribute to the attainment of 1 point.|
Sika roofing’s Low or No VOC emitting roofing adhesives and coatings solutions that can be used to obtain 3 points by not contributing to possible fumes and/or odor during building construction.
