Reflectivity or albedo is the hemispherical reflectivity integrated over a particular wavelength band of the.
Reflective roof coating energy savings.
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.
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.
This highly reflective coating uses cool pigments in the paint to increase solar reflectance and lower the surface temperature of the roof.
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.

Standard or dark roofs can reach temperatures of 150 f or more in the summer sun.
When the right reflective coating is applied building owners can enjoy significant energy savings and increased longevity of their roof system.
Lower roof temperatures have been proven to decrease internal building temperatures resulting in recurring savings from reduced air conditioning needs.
Saving energy with reflective roof coatings 1.
Surface solar reflectivity is measured using a precision spectral pyranometer with the device alternately faced.
However if you live in a hot climate that experiences warm temperatures and sunny days for a substantial portion of the year you can expect energy savings of up to 70.
The most effective energy saving finish for metal roofing is commonly referred to as cool metal roofing.
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.
This is known as the albedo effect and many studies have documented significant energy savings from simply lightening the color of a roof.
Apoc cool roof restoration systems deliver high solar reflectivity and thermal emittance which significantly reduce roof temperatures.
Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles.
Most roofing systems absorb uv rays and that heat is transferred into the building.
This means in the summer you have to run your ac more to heat the building just because the sun is shining.
All these coatings meet the energy star guidelines for energy efficiency and savings.
