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

Abstract

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