A White Roof Can Reduce Air Conditioning Costs By Up to 20 Percent

What is Ecotitanium?

Ecotitanium roofs save air conditioning energy and make them energy efficient by reflecting the sun's rays that cause intense heating of the buildings to the atmosphere, thanks to their light coloured structures. Megaron New Generation Roof Technologies waterproofing system product Çatıser Reflective increases energy efficiency by reflecting sunlight as well as its vapour-permeable structure. More contribution can be made to energy efficiency with Ecotitanium tiles applied in conjunction with Çatıser Reflective.

A White Roof Can Reduce Air Conditioning Costs By Up to 20 Percent.

The physics behind white roofs are simple. Solar energy provides both light and heat, and the heat from sunlight is easily absorbed by dark colours. However, lighter colours reflect most of the radiation and keep a building - and more broadly - city and Earth - cooler. They also re-emit some of the heat they absorb. Because the black surface absorbs the radiation, the temperature of a black roof, and hence the temperature below it, is higher before emitting most of the back. The white roof reflects most of the solar radiation and does not absorb much, so it is usually cooler. White roofs made of special vinyl material reflect not only thermal radiation, but also infrared radiation from the Sun.

Nobel Laureate Energy Minister Steven Chu's favourite idea in physics, adding that white roofs cost the same as traditional black roofs and a warm climate; "A white roof can reduce air conditioning costs by about 20 percent." When Chu spoke about white roofs, he did research from Art Rosenfeld, the commissioner of the California Energy Commission. Rosenfeld calculated that widespread white roofs and white streets throughout the United States would result in a significant reduction in carbon dioxide emissions - equivalent to getting rid of all cars for 11 years - watch Steve Chu's talk about White Roofs here. 

White roof, from Dubai to New Delhi, Osaka, Japan, reflective roofs have been adopted by local authorities looking to recapture energy costs.

California, Florida, and Georgia have adopted building codes promoting white roof installations for commercial buildings. Drawing on federal subsidy figures reserved for energy efficiency projects, state energy offices and local utilities often provide funding for cool roofs.

Where to Use White Roof?

Some roofing experts and architects argue that the parties do not take into account the climate differences or the complexities of roof construction. They say that in cooler climates, reflective roofs could mean higher heating bills. But homeowners in hot climates can also use the white roof movement in attempts to lower cooling costs. Lower cooling costs, lower energy use mean a benefit for both the pocket and our planet.
