The Changchun Construction Management and Quality Safety Conference was held yesterday. The meeting emphasized that the "warm house" project must adopt technical products that meet the relevant performance requirements of national and provincial building energy conservation and fire prevention. B1 grade (including B1 grade) and above materials are preferred for exterior wall insulation materials, and B2 grade (excluding B2 grade) materials shall not be used.

　　According to China's current standards, building insulation materials are divided into four grades (A non-combustible), B1 (flammable), B2 (combustible) and B3 (flammable).。

　　Strive to reach the end of this year, the proportion of new wall materials used in the county seat is not less than 80%。

　　This year, our province plans to add 60 million square meters of heating capacity, transform and relocate 1,000 small boiler rooms, transform 1,000 kilometers of old pipe network, implement 20 million square meters of heat metering and energy-saving renovation of existing residential buildings, and strive to complete 30 million yuan. Square meters, the implementation of the old community comprehensive renovation 10 million square meters, built 20 peaking boiler room, in Changchun, Jilin, Tonghua three cities to implement multi-heat source network operation pilot project, accelerate the construction of heating management system, promote heating information Regulatory platform construction and heat metering work。

　　In terms of highlighting the construction of heat supply capacity, cities with key cities and peaking factors below 20% should accelerate peaking capacity building. We must promptly implement the construction plan, do a good job in site selection, environmental impact assessment, and demolition work of the peaking boiler house project, study and formulate land supply, financial support, tax increase and exemption policies, and ensure the completion of construction tasks.。
