高二阅读理解Heating and cooling equipment are the biggest

发布时间:  浏览: 次  作者:爱英语吧

Heating and cooling equipment are the biggest users of energy in American homes. And homes are responsible for about one fourth of the nation's total energy use. But there are surprisingly simple ways to deeply cut energy use,its effect on the environment and its cost. David Peabody and his team at Peabody Architects design passive homes. He says the design of a passive house aims to reduce energy demand to its lowest possible level. Passive houses use no solar,geothermal or wind energy equipment. Bat they are extremely energy efficient.

Mr Peabody says passive houses cut heating and cooling costs by about 90 percent. But what sets his design apart from other "green homes" is that it looks like any other home. Peabody Architects says it is building the first passive home in the Washington. D.C. area. But it will not he the last. In Arlington. Virginia. Roger Lin and his brother Eric are also building one. Roger Lin of Southern Exposure Homes explains that windows are sealed against leaks and have three layers of glass. The windows are airtight. On a cold winter day,the temperature inside the unfinished home is a comfortable 12 degrees,or 50 degrees Fahrenheit.

David Peabody says you can find passive honks all over the world. DAVID PEABODY:

"North Africa,for example,has a passive house community designing for very hot dry climates.” The first passive design was an apartment building in Darmstadt,Germany. Two physicists helped develop it about 20 years ago. Passive houses use some specialized materials. These include precast concrete panels and insulation(隔热).They also need to have special air treatment systems. Supporters say they cost only about five or eight percent more than traditional homes. But they use 10 percent of the energy for heating and cooling.
