The 50411-2007 construction energy conservation project construction quality acceptance specification clearly stipulates that energy conservation engineering is part of the construction project.
At the end of 2010, the proportion of compulsory standards for energy conservation in new urban construction in China reached over 95%. In order to save energy and heat insulation, buildings are generally insulated with exterior materials. With the use of various materials for exterior wall insulation materials, which are widely used in public and civil buildings, fire hazards also follow.
A catastrophic fire at the new CCTV site in the Lantern Festival in 2009; a large fire that killed 58 people in the Jing'an District Teacher's Apartment in Shanghai on November 15, 2010; fireworks on February 3, 2011 in the Heping Wanxin Hotel in Heping District, Shenyang Fires caused by the igniting of decorative materials on the exterior walls are all related to the insulation defects of the external walls. Building energy conservation must be promoted, and the fire tragedy is also a wake-up call. To this end, the analysis of the impact of fire and development caused by building exterior insulation materials, targeted fire prevention measures, is an urgent problem to be solved. It is clearly defined for different fire safety requirements.
Incorporate the fire protection design of civil building exterior wall insulation system and exterior wall decoration into fire protection design review, engineering fire protection acceptance and record inspection of construction project, and incorporate insulation materials into the scope of mandatory witness inspection.
Before the introduction of relevant regulations and related technologies, it is recommended to use the external wall insulation system of non-combustible materials such as rock wool in high-rise and super high-rise buildings. This system is one of the most widely used practices in the world.
