The number of ETFE layers and the density of frits painted on ETFE are designed differently to optimize the heat transfer coefficient and shading coefficient. Meanwhile, mechanical ventilation is utilized within the cavity of the building envelope to reduce cooling load in summer. Using a simulation software, simulates and analyses the energy savi... 【基金】 科技部国家科技攻关计划项目(编号:2004BA904B02)
