Abstract:
Many residential buildings use externallyinsulated wall structures in Chongqing, P.R. China. The process of determining the economic insulation thickness was based on degree days and present worth factor when wall structure adopted different insulation materials. The optimal economic insulation thickness was related to the region of the building, air conditioning operating time, and price of insulation material. Insulation materials with better thermal performance have a shorter payback time and wider prospects for application.
