The surge of interest in using coatings for exterior cladding and roofing that contain infrared reflective pigments to keep buildings cooler has recently taken on a new and exciting future dimension.
VARI-Cool® is a unique polychromatic paint coating that offers architects and building designers a new dimension in colour design without compromising performance. This means that in addition to helping buildings stay cooler and reduce energy bills, the coatings change colour with viewing angle and how light refracts across their surface.
The first example of this type of coating in use is on the newly designed Appaloosa Branch Library in Scottsdale, Arizona, USA. The colour of the building changes from dark green to silver to mauve depending on your position. It has been commented that the coating of the building projects a light grey-green tint that matches with the surrounding landscape of desert sand and plants.
A fantastic example of the marriage of performance (the building is expected to use 32% less energy than comparable sized libraries) and colour, blending with the design of the building and its surrounding environment. I would be interested to know if any other examples exist of the use of these coatings now or in the future?
