“A wind of only 15 mph may increase the heat loss from a window surface by 47 percent or from a concrete wall by 34 percent. Therefore, heating plans have a critical relationship with windbreaks and with wind baffles.”

“Glass… is not required for the collection of solar heat. The National Physical Laboratory of Israel… has perfected a highly polished metal surface coated with a molecular-thin black layer of special paint, which absorbs more than 90 percent sunlight. The polished metal radiates very little of the heat it receives. …A south-facing wall fitted out with these plates would really "drink in" solar heat, windows, or no windows.”

“If no attempt is made to control excessive heat loss through glass… a solar house may require as much as 20 percent more fuel than an orthodox house during December and January… Wendell Thomas recognized and solved this problem… by burying the house in the ground, except for the south and east window areas. …at night… windows are covered with from inside by insulation boards and drapes…”

“As much as 70 percent of the sun's heat rays can be reflected from one's house by the installation of a white or light-colored roof.”

“About one-fifth of all the heat that enters the average house comes through windows. …external shading is by far the most efficient method for controlling interior heat build-up. The air-wash between the shading screen and the window is also very effective. The screen should have a light-colored finish… Insulation boards placed next to the window pane at night, will help prevent heat losses through glazed openings. Overhangs and horizontal sunshades placed above south-facing windows serve effectively as heat reducers.”

“A perfectly flat roof permits up to 50 percent more heat gain that a pitched roof… This illustrates the failure of the flat-roof construction to get natural, hot air flow out from under the eaves.”

“What is the purpose of houses? It is to protect us from the wind and cold of winter, the heat and rain of summer, and to keep out robbers and thieves. Once these ends have been secured, that is all. Whatever does not contribute to these ends should be eliminated.”

“It will take more time for the change we have to effect, but we don't have more time. The carbon dioxide on Earth, just in the last four years, has increased from.03 percent to.04 percent. And the change will have a significant impact on everyone.”

“In 1970, the developed nations had twice as big a share of the global population as the Muslim world: 30 percent to 15 percent. By 2000, they were at parity: each had about 20 percent.
And by 2020?”
