At an urban, as well as building level, an increase in vegetated areas and water bodies will reduce the impact of the UHIE and increase comfort for the entire microclimate. A combination of highly reflective and light colored roofs and/or vegetative roofs may be used to mitigate UHIE, based on roof location, area, accessibility, and usage.

Increased recognition of the benefits of cool roofing has led to the adoption of cool roof measures in.

What is a cool roof?
A cool roof is one that reflects most of the incident sunlight and efficiently emits some of the absorbed radiation back into the atmosphere, instead of conducting it to the building below. As a result the roof literally stays cooler, with lower surface temperatures, keeping the building at a cooler and more constant temperature. The term, ‘cool roof’ refers to the outer layer or exterior surface of the roof which acts as the key reflective surface. These roofs have higher solar reflectance than a typical roof surface. The term ‘cool roof’ encompasses an extensive array of roof types, colors, textures, paints, coatings, and slope applications.

Benefits of Cool Roofs
Cool roofs provide numerous benefits at the micro level as well as the community level. Cool roofs energy codes and the inclusion of cool roofing as part of green building initiatives.
