Thermal characteristics and energy consumption analysis of external respiration double-skin facades

Taking an external respiration double-skin facade building in Changsha as an example, establishes a thermal network model and a mathematical model. Simulates and calculates integrated heat transfer coefficients and design cooling and heating loads for different facade buildings by Window6.2 and EnergyPlus2.2 softwares. Analyses the influences of glass type and airspace width, and energy consumption and economic feasibility.
