Application of Aerogel in Building Energy-saving

摘要

Each year, China consumes more than 1.4×l0～8t coal for supplying heat. However, an urgent problem is that a large percent of the heat is not fully used but lost to external through the windows, walls and roofs. The paper mainly talks about how to improve the thermal insulation property of the buildings by adopting aerogel in order to reduce the unnecessary consumption of coal. Aerogel is a solid-state material with a density lower than that of the air and extraordinary performances in heat insulation and fire resistance which can be seen in the fact that the temperature it can withstand is more than ten times than other common materials. This paper aims at studying the application of particle aerogels, plate aerogels, and glass aerogels in the construction industry. And some application methods of aerogel are put forward connected with CRTS slab, architectural glass and non-bearing structure.
