Reflective Roof Coating Energy Savings

This means in the summer you have to run your ac more to heat the building just because the sun is shining.

Reflective roof coating energy savings.

Reflectivity or albedo is the hemispherical reflectivity integrated over a particular wavelength band of the. Surface solar reflectivity is measured using a precision spectral pyranometer with the device alternately faced. This highly reflective coating uses cool pigments in the paint to increase solar reflectance and lower the surface temperature of the roof. A cool roof under the same conditions could stay more than 50 f cooler and save energy and money by using less air conditioning.

Apoc cool roof restoration systems deliver high solar reflectivity and thermal emittance which significantly reduce roof temperatures. 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.

Saving energy with reflective roof coatings 1. For anyone who may not know a reflective roof coating saves energy in your building by reflective uv rays back into the atmosphere. Lower roof temperatures have been proven to decrease internal building temperatures resulting in recurring savings from reduced air conditioning needs. 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.

Savings are important for both old and new levels of insulation. This is known as the albedo effect and many studies have documented significant energy savings from simply lightening the color of a roof. 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. Most roofing systems absorb uv rays and that heat is transferred into the building.

The most effective energy saving finish for metal roofing is commonly referred to as cool metal roofing. All these coatings meet the energy star guidelines for energy efficiency and savings. When the right reflective coating is applied building owners can enjoy significant energy savings and increased longevity of their roof system.
