Beginning in pre-design and continuing throughout the design phases, identify and use opportunities to achieve synergies across disciplines and building systems. Use the Discovery and Analyses Guidelines described in the credit to inform the owner s project requirements OPR , basis of design BOD , design documents, and construction documents.
GAF s roofing, insulation, and hardscape coating products contribute to the integrative process in both the Energy- Related Systems and Water-Related Systems analysis, as well as the Implementation criteria. GAF and Energy-Related Systems Hardscape reflectivity, thermal building envelope attributes roof insulation , roofing systems, and exterior materials analyses reflective or vegetative roofing GAF and Water-Related Systems Supply sources of on-site rainwater related to roofing systems and catchment.
Landscaping and rainwater management related to vegetative roofing. On-Site Restoration. Intent SS Credit 4 points GAF's Eligible Option Rainwater Management To reduce runoff volume and improve water quality by replicating the natural hydrology and water balance of the site, based on historical conditions and undeveloped ecosystems in the region.

Products are not reviewed or certified under LEED. See page 7. For example, roofing materials having a higher SRI value than those listed in Table may help offset nonroof hardscape areas not meeting the SR values, depending on the relative proportions of roof to non-roof areas and mitigation strategies in the project. Minimum solar reflectance index value, by roof slope.
Provide shade with structures covered by energy generation systems, such as solar thermal collectors, photovoltaics, and wind turbines. Use the existing plant material or install plants that provide shade over paving areas including playgrounds on the site within 0 years of planting. Install vegetated planters. Plants must be in place at the time of occupancy permit and cannot include artificial turf.
Table 2. Because it is a combined performance calculation, this means any areas that exceed the minimum SRI or SR values can actually help carry the areas that are below the minimum SR or SRI values. Any roof used to shade or cover parking must have an initial SRI of at least 39 at installation or a three-year aged SRI of at least 32, 2 be a vegetated roof, or 3 be covered by energy generation systems, such as solar thermal collectors, photovoltaics, and wind turbines.
Standard non-roof or roof calculation Equation 2. Aged SR 0. EnergyGuard Polyiso roof insulation has an Industry-wide generic EPD, contributing as one-half product value towards credit achievement. EnergyGuard Polyiso roof insulation contributes with its recycled content. Building product disclosure and optimization. The Superdome needed a roof coating that would resist the buildup of dirt and biological growth, keeping the city s crown jewel bright white and ensure solar reflectivity to lower cooling demands and emissions.
In a weighted performance calculation for this credit, the roof SRI of 0 would also help offset any hardscape areas that fell below the required minimum SR value in a v4 project. This reduction then contributes to lowering cooling demands and costs of the building while also reducing CO 2 emissions and pollution. StreetBond increased the Solar Reflectance of the asphalt parking pavement by reflecting more of the summer sun s heat. The Integrative Process identifies design opportunities to achieve synergies across disciplines and building systems.
In this case, the default decisions for hardscape surfaces are explored, resulting in a solution to the traditional non-reflective asphalt parking pavement, without the cost of concrete. Option 2. GAF can contribute to achieving this credit option by supporting the design and construction team with roofing system drawings and specifications for the roofing portions of the thermal envelope.
Intent EA Credit 2 -8 points GAF's Eligible Option Optimize Energy Performance To achieve increasing levels of energy performance beyond the baseline in the prerequisite standard to reduce harmful environmental and economic impacts associated with excessive energy use. Calculate the energy produced by the on-site renewable system as a percentage of the yearly energy cost of the building.
