- 16 - LEED and Sika Sika materials and systems can impact following LEED categories: Sustainable Site (SS) Energy and Atmosphere (EA) Indoor Environmental Quality (IEQ) Sika can help to achieve LEED credits: Materials and Resources (MR)
Sika-relevant Credits Material and Resources - 17 - Credit 4 Indoor Environmental Quality (IEQ) Credit 4.1 Credit 4.2 Credit 4.3 Credit 5 Regional Materials (MR) Low-Emitting Materials Adhesives and Sealants Low-Emitting Materials - Paints and Coatings Low-Emitting Materials Flooring Systems 500 miles Should be considered in case by case.
Sika-relevant Credits for Flooring, Coating (example) - 18 - Credit 4.2 Low-Emitting Materials, Paints and Coatings (IEQ) Clear wood finishes, floor coatings, stains, primers > SCAQMD rule 1113 Example floor coatings VOC < 100 g/l. Sikadur Sikafloor SikaGard All Cement Products
- 19 - Sika-relevant Credits for Sealants, Adhesives (example) Credit 4.1 Indoor Environmental Quality (IEQ) Low-Emitting Materials, Adhesives and Sealants SCAQMD rule 1168, VOC Content Example ceramic tile adhesive < 65 g/l wood flooring adhesives < 100g/l Sikaflex Sikasil SikaBond
- 20 - LEED - Credit for Sika Sarnafil Roofing (example) Credit 2 On-Site Renweable Energy (EA) Use on-site renewable energy systems to offset building energy costs. Calculate project performance by expressing to energy produced by the renewable systems as percentage of the buildings annual energy cost. Credit 6 Green Power (EA) Engage in at least a 2-year renewable energy contract to provide at least 35% of the buildings electricity from renewable sources. Example of Sika products: Sika offers roof waterproofing master membranes for lamination of photovoltaic cells.
LEED - Credit for Sika Sarnafil roofing (example) Credit 7.2 Heat Island Effect (SS) High reflecting Use roofing materials with solar reflectance index >78 for min. 75% of roof surface (low sloped roofs). Example, high reflecting roof waterproofing membrane, e.g. Sarnafil S 327 Energy Smart. Green roofs Install a vegetated roof that covers at least 50% of the roof area. Example of Sika products: e.g. Sikaplan 45, Sikaplan SGMA, Sarnafil G 476. - 21 -
