Sentences with phrase «white roofs reduce»

Not exact matches

The roof is a high albedo system (white roof) which reduces cooling load.

New York's Mayor Michael Bloomberg has committed city funds to converting some of the area's black tar and stone roofs into highly reflective white roofs, which reduce temperatures on roofs and cooling costs but fail to address the storm water runoff problem.

And white roofs can reduce precipitation as well, by reducing the amount of warm, humid air rising and, thus, the number of clouds and eventual rainfall.

«Adaptation to urban - induced climate change depends on specific geographic factors,» Georgescu adds, noting that white, reflective cool roofs work well in California, but could reduce rainfall from Florida up the U.S. east coast, for example.

A white roof reflects the sun's light and heat, so a couple of coats of paint can reduce your carbon emissions and take about 20 percent off your energy bills.

For the more mainstay grey, black, and white paint jobs, and provided the buyer foregoes the sunroof, a contrasting white roof is available to create a two - tone colour scheme that's not only visually distinct but also functional: white bounces back more solar rays in the summer, reducing the load on the A / C system.

It's long been known that white roofs reflect more heat back into space, reducing the amount of electricity used for A / C and thus drastically cutting down on energy consumption.

The researchers have focused on white solar panels, not just because of the versatility of the color, but because white solar panels would stay cooler, which boosts their efficiency, and using them over large sections like the roof would keep the buildings themselves cooler, which would reduce the energy demand of cooling buildings.

As to the reason for painting a roof white or making it reflective is to attempt to reduce the solar insolation conversion from UV to IR.

Some approaches, like turning biomass into biochar, a charcoal whose carbon resists breakdown, and painting roofs white to increase their reflectivity and reduce air - conditioning demand, are relatively benign, but would have minimal effect on a global scale.

I can see two effects — reduced need for A / C (one estimate I saw was 6 - 10 tons of A / C (12,000 BTU = 1 ton) from spraying a flat black rubber roof with water in a dry environment and letting it evaporate — but a white roof wouldn't need spraying in the first place), and the other is from increasing reflection into space?

CrossIron Mills has a white membrane roof which reflects heat and reduces interior cooling requirements.

Painting flat roofs of homes and commercial buildings white would reflect more of the sun's heat back to space and reduce electricity used for air conditioning by as much as 15 percent, Chu told reporters today in London, citing research by Arthur Rosenfeld, a member of the California Energy Commission.

We have found that white roofs do provide a low - cost solution that can help buildings reduce energy costs, in a wide variety of climates, as well as cool the atmosphere regionally and globally.

Say we need 20 years to get our sh*t together and reduce emissions, but we only have 10 before the tipping point (where ice melting becomes irreversible, for example), maybe it's worthwhile to pump out massive amounts of harmful junk, paint roofs white, whatever is possible, to avoid that tipping point.

A white thermoplastic roof membrane reduces energy costs by reflecting solar energy thereby eliminating additional stress on the cooling system.
