Technical Suitability of Energy Saving Scheme for Optimizing the Thermal Insulation Layer Thickness of Residential Building Exterior Wall

From the perspective of technical suitability, this paper comparatively analyzed economical thickness and suitable exterior wall thermal insulation material with highest energy saving rate building envelop, attained relationship, curves, model material. The purpose is to provide useful evidences for residential buildings optimization design wall, so that architectural designers could be inspired consider energy-saving issue from multiple angles such as economy environment, optimal scheme most beneficial environment created. This lays a theoretical basis making investment decisions avoiding unwise investment.
