Energy-saving Transformation Research on the External Wall of Existing Residential Buildings in Nanjing Area
The percentage of the wall energy consumption in the building envelope energy consumption is more than 30%and external wall insulation can reduce building envelope energy consumption to reduce the total energy consumption of the building.In this paper,the external wall of existing residential buildings and three kinds energy saving transformation external wall systems have been simulated with DesignBuilder energy consumption simulation software.It analyzed three kinds of external wall insulation systems energy consumption status.The results show that not only the same insulation system at different insulation layer thickness have different insulation effects,but also different insulation systems with the same insulation layer thickness have quite different insulation effects.Finally,the paper compared the economy of the three insulation systems and external wall insulation system owning the best comprehensive benefits in the external wall Energy-saving transformation of existing residential buildings in Nanjing Area have been obtained.
