Active cool roof effect. 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. Standard or dark roofs can reach temperatures of 150 f or more in the summer sun. Overall energy demand reduces between 1 and 8 5 relative to an albedo of 0 1.

This article throws light on cool roof technology with a special emphasis on its suitability in the indian context. Whereas darker traditional roofing materials absorb sunlight the reflective surfaces of a cool roof reflect it away. What constitutes a cool roof. Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles.

This project has b. With all the focus on green building these days the market is heating up with interest in cool roof technology. Impact of cool roofs on cooling system efficiency. In light of this cool roofing is one of the main strategies used to prevent future occurrences of heat island effects cool roofing is an emergent and powerful technology used for temperature control of buildings and areas.

7 mitigating urban heat island using cool roof technologies pp. Cool roof requirements vary by region but generally are based on solar reflectance and. Cool roofs are designed to lower the temperature of your home in summer months making you more comfortable and potentially reducing your energy bill. This cool roof technology was demonstrated under the cool roof and passive ventilation project implemented by taru leading edge pvt.

Roof reflectivity of 0 6 0 7 is optimum for london climate. It is a relatively cheap option with substantial benefits. This results in lower absorption of solar heat and a cooler 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. A cool roof prevents heat absorption by reflecting the sun s heat and then emitting its radiation back into the atmosphere. Cool roofs is a green building technology that is especially suited to the climate of the india. The study includes experiments and thermal modelling.

A cool roof under the same conditions could stay more than 50 f cooler and save energy and money by using less air conditioning. Roof temperature is rated via solar reflectance and thermal emittance with ratings ranging between 0 and 1. Highlights we studied the energy impact of a cool roof in an office building in london. In today s market a cool roof is defined by the reflectivity and emissivity requirements set by either title.
