目前,我国每年墙体材料生产能耗达5000万吨标准煤,建筑采暖能耗近一亿吨标准煤,全国每年烧砖毁田七八万亩,大量工业废渣未加以利用。按照国家建材局和建设部“八五”计划,到1995年底,新型墙体材料比重由目前的5％提高到15％,每年可节省生产能耗标准煤400万吨,节约耕地一万亩,利用废渣7500万吨。采暖地区新住宅和旅游建筑节能率要达到30％,加上旧房改造,每年可节省400万吨标煤;还可减轻建筑物自重,节省运输量七亿吨公里。
At present, China’s annual wall material production energy consumption of 50 million tons of standard coal, building energy consumption of nearly 100 million tons of standard coal, the country each year burned bricks destroyed 78 million acres, a large number of industrial waste residue has not been used. According to the “Eighth Five-Year Plan” of the National Building Material Administration and the Ministry of Construction, by the end of 1995, the proportion of new wall materials will be increased from the current 5% to 15%. Each year, 4 million tons of standard coal with energy saving can be saved, and 10,000 acres of arable land can be saved. Use 75 million tons of waste residue. The energy saving rate for new residential buildings and tourism buildings in heating areas should reach 30%. With the transformation of old houses, 4 million tons of standard coal can be saved each year. It can also reduce the weight of buildings and save 700 million tons of transportation.
