building designers and developers that are pursuing the heat island reduction credit for leed certification require documentation of the solar reflectance index (sri) for their project's roofing materials, shade giving structures, and paving materials. under the u.s. green building council's leed 2009 rating system, credits,
an example would be that the efficiency of a pv system frequently improves when it is placed above a cool roof. because of their lighter color, cool roofs reflect sunlight (solar reflectance) and efficiently emit thermal radiation (thermal emittance). by cooling the roof and lessening heat transfer into the building, cool roofs,

cool-roof. our cool-roof™ pavers utilize a high reflective value and low emissivity rate resulting in a high solar reflectance index (sri) value; tile tech cool-roof™ pavers have a minimum sri value of 78. this high sri value allows you to meet the needs for “leed” certified projects when used on your roof and decks.
solar reflectivity (r) &. solar reflectance index (sri) by color. solar reflectivity or reflectance is the ability of a material to reflect solar energy from its surface back into the atmosphere. the sr value is a number from 0 to 1.0. a value of 0 indicates that the material absorbs all solar energy and a value of 1.0 indicates total,
solar reflective cool-roof™ pavers are ideal for creating functional and attractive rooftop, terraces, balconies and plazas. , cool-roof-pool-deck , our cool-roof™ pavers utilize a high reflective value and low emissivity rate resulting in a high solar reflectance index (sri) value; tile tech cool-roof™ pavers have a,
concrete provides reflective surfaces with good solar reflective index (sri) that helps in urban heat island reduction. , other options include placing a minimum of 50% of parking spaces undercover (such as underground, under deck, under roof, and under building); using an open-grid pavement system with more than,
whilst solar reflectance index data is not currently available for all pavers in our range, the following data for the kronos range of porcelain pavers will give an indication of sri values that can be expected across the complete color range of pavers, ranging from lightest to darkest colors.
trugrain decking may qualify as a non-roof strategy for reducing the urban heat island effect due to the qualifying solar reflectance index value of certain colors of the resysta 2k sealer rfs. materials & resources. building product disclosure & optimization – material ingredients (1 point). trugrain products have a,
solar reflectance index (sri). a measure of the constructed surface's ability to stay cool in the sun by reflecting solar radiation and emitting thermal radiation. it is defined such that a standard black surface (initial solar reflectance 0.05, initial thermal emittance 0.90) has an initial sri of 0, and a standard white surface (initial,
