随着我国国民经济的迅速发展,住宅建筑量也愈来愈大,我国城镇建筑每年约为1亿平方米左右。在建筑中如何研究、应用、发展能耗低、保温好的新型轻质建筑材料,是值得重视的问题。住宅建筑的建造能耗也称一次性能耗,是指住宅在建造过程中所耗用的能源,包括材料能耗、运输能耗和施工能耗,一般材料能耗要占建造能耗的52.9～80.5%。砖混建筑的材料能耗最大,占建筑能耗的79%,框轻建筑较低,占建造能耗的52.9%。可见发展和应用新型轻质建筑材料是建筑节能的重要途径。
With the rapid development of China’s national economy, the amount of residential buildings is also increasing. The annual urban construction in China is about 100 million square meters. How to research, apply and develop new lightweight building materials with low energy consumption and good insulation in buildings is a problem worthy of attention. The energy consumption for the construction of residential buildings is also called one-time energy consumption. It refers to the energy consumed during the construction of a house, including material energy consumption, transportation energy consumption and construction energy consumption. The energy consumption of general materials accounts for 52.9 to the energy consumption for construction. 80.5%. The energy consumption of materials in masonry buildings is the largest, accounting for 79% of the building energy consumption, and the construction of light buildings is relatively low, accounting for 52.9% of the construction energy consumption. It can be seen that the development and application of new lightweight building materials is an important approach for building energy conservation.
