Cool roof technology.

By lowering energy use cool roofs decrease the production of associated air pollution and greenhouse gas emissions. Cool roofs is a green building technology that is especially suited to the climate of the india. This article throws light on cool roof technology with a special emphasis on its suitability in the indian context. Roof temperature is rated via solar reflectance and thermal emittance with ratings ranging between 0 and 1.

As in golf the higher the rating the lower the. Standard or dark roofs can reach temperatures of 150 f or more in the summer sun. Design design and inspire view all. A cool roof transfers less heat to the building below so the building stays cooler and uses less energy for air conditioning.

Total protection is more than shingle deep. A cool roof is a roofing system that delivers higher solar reflectance the ability to reflect the visible infrared and ultraviolet wavelengths of the sun reducing heat transfer to the building and higher thermal emittance the ability to radiate absorbed or non reflected solar energy than standard designed roofing products. With all the focus on green building these days the market is heating up with interest in cool roof technology. Yet you may not be familiar with what exactly the term means so let s give you a quick primer on cool roof technology with a special emphasis on its suitability in the indian context.

What constitutes a cool roof. A cool roof is a roof that reflects more sunlight and absorbs less heat than a standard roof lowering roof temperature and releasing less heat into the environment. Surenail technology nailing zone performance streakguard algae protection cool roof energy performance roofing system. Cool roofs are designed to reflect more energy and heat than traditional roofs.

This results in lower absorption of solar heat and a cooler roof. Cool roofs can reduce air temperatures inside. It is a relatively cheap option with substantial benefits. Cool roofs is a green building technology that is especially suited to the climate of india.

Reduced air pollution and greenhouse gas emissions. Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles. Whether these new roofs use new materials new construction techniques or both the ultimate goal is to maintain or improve a building s comfort at a substantially lower. A cool roof under the same conditions could stay more than 50 f cooler and save energy and money by using less air conditioning.

Historically cool roofs have been either white. Cool roofing is an emergent and powerful technology used for temperature control of buildings and areas. Improved human health and comfort. Cool roof requirements vary by region but generally are based on solar reflectance and.

It is a relatively cheap option with substantial benefits.
