Dow Cool Roof Energy Calculator
Energy efficiency in modern buildings offers significant potential for achieving sustainability targets like reduced CO2 emissions while at the same time improving living standards of urban populations. The most significant contribution to this is reducing the amount of energy used to control the internal temperatures of buildings. This can be achieved through thermal insulation in cooler climates, while in warmer geographies measures that mitigate the effects of solar radiation such as Cool Reflective Roof Coatings (CRRC) are very effective.
Cool Reflective Roof Coatings (CRRC)
A cool reflective roof coating not only helps reduce internal temperatures and thus energy cost for cooling; it also helps to prolong the service life of roofs by providing protection against climatic elements.
Dow’s Cool Roof Energy Calculator
Dow’s Cool Roof Energy Calculator has been designed to help you estimate possible energy savings by using CRRC technology on your roof. Overall energy consumption as well as room and roof temperatures are calculated by performing building energy simulations for 3 types of buildings (residential, commercial and warehouses) at different roof & wall build ups and sizes in 15 selected cities from across Europe, the Middle East, Africa and India
