People comfort
The heat can severely overwhelm the people of a building, a school, a retirement home or even offices in the city. Taking care of people’s well-being is a noble value. It is also environmentally friendly, since the reduction in temperature benefits the urban island, which also sees the average temperature of the block decrease. It is not for nothing that New York’s skyscrapers have white roofs.
Saving energy
Since the temperature of the roof surface is reduced, cooling devices such as those used for air conditioning or refrigerators are less stressed. Not only are they not pushed to the maximum, but they also reduce power consumption. Directly visible on your energy bill and your carbon footprint!
