White Roofs Catch on as Energy Cost Cutters

[Nonno]

"SAN FRANCISCO — Returning to their ranch-style house in Sacramento after a long summer workday, Jon and Kim Waldrep were routinely met by a wall of heat.

“We’d come home in the summer, and the house would be 115 degrees, stifling,” said Mr. Waldrep, a regional manager for a national company.

He or his wife would race to the thermostat and turn on the air-conditioning as their four small children, just picked up from day care, awaited relief.

All that changed last month. “Now we come home on days when it’s over 100 degrees outside, and the house is at 80 degrees,” Mr. Waldrep said.

Their solution was a new roof: a shiny plasticized white covering that experts say is not only an energy saver but also a way to help cool the planet.

Relying on the centuries-old principle that white objects absorb less heat than dark ones, homeowners like the Waldreps are in the vanguard of a movement embracing “cool roofs” as one of the most affordable weapons against climate change. "

Isn't cooling the planet changing the climate?

NY Times what idiots

I hope the NAACP and Prof Gates don't hear about this.

Since when is it national news that a white roof reflects heat away from the house?

Since the dems took control of the media.

They are doing that with school buses now, those big yellow boxes get really hot in the summer.

But having a dark roof decreases your heating costs in the winter :shrug:

Then it's time to develop the electro-screen technology like in windows. No power applied, it's transparent and the underlying dark roof absorbs heat. Voltage applied, and the roof panels become reflective. Could be triggered by a thermostat in the attic space based on time of year. Power derived from solar panels.

Who wants to help me develop this?
