United States Air Force<br />“… After the application of the coating, <br />the average peak temperature in the <br />warehouse area dropped to 86° F, <br />a decrease of 17° F. “<br />- James A., Capt. USAF Chief RSD of Civil Engineering<br />
United States Army<br />“… a 64° F reduction in roof surface temperature, a 23° F reduction in attic temperature and a 10° F reduction in room temperature as a result of the insulative and reflective value of the coating.”<br /> - Benjamin S., Col, Dept. of the Army<br />
Camp Robinson, North Little Rock, AR Army Reserve <br />
“By our own tests, we have shown a temperature reduction ranging from eight to eighteen percent in the interior ambient temperature…In the blazing Arizona sun, it (Astec) shows virtually no sign of deterioration…”<br />- Hal D., Director of Pupil Transportation, Scottsdale Public Schools <br />
Cool Roofing improves insulation performance<br />“The thermal resistance of insulation installed immediately below a black membrane has been found to be up to 30% lower than advertised, when measured at peak summertime temperatures in Austin, Texas.”<br /> - Konopacki and Akbari, 2001<br />
LEED Condition: <br />Sustainable Sites<br />Energy Star Standard.<br />Initial reflectance of at least 0.65 reflectance & at least 0.5 when tested in 3 years minimum emissivity of 0.90 for a minimum of 75% of the roof surface. <br />
Added roof life-cycle cost savings for <br />ENERGY STAR® Fluid Applied Cool Roof Systems.<br /><ul><li>Qualified roof products maintain a more constant temperature and reduce thermal shock; cool rain/hot roof causes sharp drop in temperature, extremes of expansion and contraction.
Thermal Shock = stress and roof degradation.</li></li></ul><li><ul><li>According to the EPA about $40 billion is spent annually in the United States alone to air condition buildings about 1/6 of all electricity generated in a year.
ENERGY STAR® qualified roof products reduce the amount of air conditioning needed in buildings, and reduce energy bills by up to 50%. – Department of Energy</li></li></ul><li><ul><li>A reflective roof can reduce peak cooling demand by 10-15%. As a result the building owner may be able purchase a smaller, more efficient and less expensive cooling system. -EPA
Existing cooling systems will not have to work as hard to maintain the same comfort levels and may require less maintenance.</li></li></ul><li>LEED Condition: <br />Indoor Environmental Quality<br />Comply ASHRAE STD 55-2004<br />
What is Standard 55-2004?<br /><ul><li>The standard specifies conditions of indoor thermal environment that occupants will find acceptable.
The standard is intended for use in design, commissioning and testing of buildings and other occupied spaces and for the evaluation of existing thermal environments. </li></li></ul><li>
