从2000年起,美国房屋所耗能源超过了交通业和产业界,消耗美国能源总供应的1/3。近年来,为了节能和环保,美国能源部正在大力推广“零能耗住宅”新技术。通过改进建筑设计和材料,美国房屋能耗已比1980年减少了30%。“零能耗住宅”有室内温度变化小、不怕停电、节约能源和减少污染 Since 2000, U.S. homes have consumed more energy than transportation and industries, consuming 1/3 of the total energy supply in the United States. In recent years, in order to save energy and protect the environment, the U.S. Department of Energy is vigorously promoting the new technology of “zero energy consumption housing”. By improving building design and materials, energy consumption in the United States has been reduced by 30% over 1980. “Zero-energy homes” have small indoor temperature changes, are not afraid of power outages, save energy and reduce pollution
