Cool Roof Technology

This article throws light on cool roof technology with a special emphasis on its suitability in the indian context.

Cool roof technology.

Cool roof requirements vary by region but generally are based on solar reflectance and. Cool roofs can reduce air temperatures inside. What constitutes a cool roof. Cool roofs is a green building technology that is especially suited to the climate of india.

It is a relatively cheap option with substantial benefits. Cool roofing is an emergent and powerful technology used for temperature control of buildings and areas. Cool roofs are designed to reflect more energy and heat than traditional roofs. Cool roofs is a green building technology that is especially suited to the climate of the india.

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. 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. Historically cool roofs have been either white. A cool roof prevents heat absorption by reflecting the sun s heat and then emitting its radiation back into the atmosphere.

With all the focus on green building these days the market is heating up with interest in cool roof technology. 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. It is a relatively cheap option with substantial benefits. Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles.

Standard or dark roofs can reach temperatures of 150 f or more in the summer sun. A cool roof under the same conditions could stay more than 50 f cooler and save energy and money by using less air conditioning. One of the most popular technologies the industry has developed is cool roof technology. Reduced air pollution and greenhouse gas emissions.

By lowering energy use cool roofs decrease the production of associated air pollution and greenhouse gas emissions.
