Cool Roof Coatings - The Green Design

SpecialChem / Mar 3, 2010

Basically, dark-colored roofs absorb heat and increase cooling costs. By coating the roofs white (or paler color), a "cool roof" reflects heat away and keeps the building more comfortable. Cool roof coatings help roofs to last longer, increase the efficiency of air conditioning equipment and greatly reduce peak energy use to avoid brownouts of blackouts during hot summer months. The cool roof coatings market is a very dynamic segment that is evolving quite rapidly. In 2007, the ChemQuest Group pegged the value of the cool roof coatings market at $430 to $440 million, with white elastomeric products accounting for $290 million and colored coatings containing infrared (IR) reflective pigments making up the remainder. There appear to be two key drivers for the cool roof coatings market, both of which relate to reduced energy consumption. The first driver originates with consumers who are looking to lower air conditioning costs and be more environmentally conscious. The second is regulatory based, as several states and cities in the U.S. have passed, or are planning to incorporate, requirements for cool roof performance in their building codes (Energy Star and California Title 24, for example. According to Energy Secretary Chu's Geoengineering concept, a global "cool roofs" strategy can achieve big benefits - the equivalent of several trillion dollars worth of CO2 reductions. The strategy proposed "is equivalent to taking the world's approximately 600 million cars off the road for 18 years."
