Experts talk about building thermal insulation technology

Recently, the building thermal insulation Professional Committee of China Building Energy Conservation Association organized the theme salon activity of "China Real Estate Industry General Federation meeting - key technology selection and classic case sharing of building thermal insulation". The participants exchanged and discussed from the fields of residential industrialization, passive building energy saving and external wall insulation, which are widely concerned at present.

At present, the industrialization of housing is being paid more and more attention by the industry. Experts attending the meeting believe that the prefabricated construction of housing has its own characteristics: first, it basically realizes the modular and standardized design; second, it has guaranteed quality, prefabricated building components are industrialized and standardized production, so as to avoid human factors; third, it reduces waste; fourth, it can control the construction period and cost; third, it can improve the quality of housing; The fifth is to reduce the labor cost, reduce the labor intensity and security risks. "Passive" energy-saving buildings are developed on the basis of low-energy buildings, which are more and more popular in European countries. According to the experts attending the meeting, the passive building energy saving can be further improved by optimizing the building design, controlling the building shape coefficient, adopting composite thermal insulation materials to reach the energy saving standard, improving the air tightness of the building, controlling the ventilation system with heat recovery, scientific window wall ratio and shading system, etc. The suitable technology can be selected according to different regional characteristics.

In recent years, the occurrence of many building insulation fire incidents has aroused the thinking of insulation and fire prevention from all walks of life. The fire performance of insulation materials has attracted great attention in the industry. With the acceleration of urbanization, the market of building organic thermal insulation materials with good thermal insulation performance and high cost performance will shine brilliantly.

Experts attending the meeting agreed that the supervision and inspection mechanism should be continuously improved, the responsibility problems in the project should be implemented, there should be laws to follow, there should be responsibilities to pursue, there should be evidence to punish, and the market access threshold of the industry should be continuously improved. China Building Energy Conservation Association building thermal insulation professional committee should focus on recommending a number of industry leading enterprises, high quality products.
