Reflective roof coating energy savings.

The most effective energy saving finish for metal roofing is commonly referred to as cool metal roofing. Reflectivity or albedo is the hemispherical reflectivity integrated over a particular wavelength band of the. Savings are important for both old and new levels of insulation. Lower roof temperatures have been proven to decrease internal building temperatures resulting in recurring savings from reduced air conditioning needs.

Surface solar reflectivity is measured using a precision spectral pyranometer with the device alternately faced. Apoc cool roof restoration systems deliver high solar reflectivity and thermal emittance which significantly reduce roof temperatures. Standard or dark roofs can reach temperatures of 150 f or more in the summer sun. This highly reflective coating uses cool pigments in the paint to increase solar reflectance and lower the surface temperature of the roof.

Most roofing systems absorb uv rays and that heat is transferred into the building. Saving energy with reflective roof coatings 1. When the right reflective coating is applied building owners can enjoy significant energy savings and increased longevity of their roof system. For anyone who may not know a reflective roof coating saves energy in your building by reflective uv rays back into the atmosphere.

The total value of base plus peak energy savings offered by a reflective roof is significant averaging more than 1000 annually in most climate zones for a typical commercial building. This means in the summer you have to run your ac more to heat the building just because the sun is shining. 1 cool your roof cool roofs are lighter in color than traditional black asphalt or dark wood shingles and save energy by reflecting light and heat away rather than absorbing them. If not your energy savings from applying a reflective roof coating could range anywhere from 20 to 70 when it s all said and done.

Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles. All these coatings meet the energy star guidelines for energy efficiency and savings. Please remember the energy savings that can be achieved with reflective roofing is highly dependent on facility design insulation used climatic conditions building location and building envelope efficiency.
