Comparison and Selection of Thermal Insulation Optimization Scheme of Prefabricated Steel Structure in Hot Summer and Cold Winter Area Based on GIOWA Operator
With the continuous progress of building energy-saving technology,composite wall insulation system is also constantly innovative.Generally speaking,composite wall insulation systems can be divided into external wall exter-nal insulation systems,external wall internal insulation systems,and so on.In response to the country's call to vigor-ously develop the construction industry,its applicability in practical applications need to be further studied.The ap-plicability of the optimized prefabricated steel structure energy saving scheme and the uninsulated scheme is evalua-ted comprehensively.The result shows that it is necessary to optimize the energy saving design of the prefabricated steel structure composite wall.The GIOWA operator is selected as the suitability evaluation modeling method,and environmental impact,safety and fire protection,energy saving,economy,market acceptance and wall thickness are selected as the comprehensive evaluation factors of exterior wall suitability.Four typical cities in hot summer and cold winter areas(Chongqing,Xuzhou,Nanchang and Zunyi)are selected as the research objects and its applicability in different cities are studied.The results show that Chongqing area wants to choose extruded polystyrene board as the in-sulation material of scheme 3,while Xuzhou,Nanchang and Zunyi area want to choose vitrified microbead inorganic insula-tion board as the insulation material of scheme 4,which wants to reduce energy consumption and be more economical.
