Cool roof technology journals.

What constitutes a cool roof. With all the focus on green building these days the market is heating up with interest in cool roof technology. It is a relatively cheap option with substantial benefits. 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.

Cool roofs is a green building technology that is especially suited to the climate of the india. Cool roof requirements vary by region but generally are based on solar reflectance and. Highlights we studied the energy impact of a cool roof in an office building in london. Roof reflectivity of 0 6 0 7 is optimum for london climate.

It is a relatively cheap option with substantial benefits. Cool roofs are designed to lower the temperature of your home in summer months making you more comfortable and potentially reducing your energy bill. Cool roofs achieve this by reflecting some of the infrared ir light from the sun. Overall energy demand reduces between 1 and 8 5 relative to an albedo of 0 1.

Standard or dark roofs can reach temperatures of 150 f or more in the summer sun. 7 mitigating urban heat island using cool roof technologies pp. Cool roofs is a green building technology that is especially suited to the climate of india. 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.

This results in lower absorption of solar heat and a cooler roof. The study includes experiments and thermal modelling. 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. This project has b.

Roof temperature is rated via solar reflectance and thermal emittance with ratings ranging between 0 and 1. This article throws light on cool roof technology with a special emphasis on its suitability in the indian context. Active cool roof effect. Thermal comfort improves by 2 5 c but heating demand increases by 10.

A cool roof under the same conditions could stay more than 50 f cooler and save energy and money by using less air conditioning. A cool roof prevents heat absorption by reflecting the sun s heat and then emitting its radiation back into the atmosphere. This cool roof technology was demonstrated under the cool roof and passive ventilation project implemented by taru leading edge pvt. Impact of cool roofs on cooling system efficiency.
