Abstract：

The building with indoor snow field needs more complicated refrigerating and air conditioning system than other conventional buildings and it could not be analysed using the normal way. Because of the huge energy consumption, the snow field is strict about the requirements of building envelope. Taking an indoor snow field with the ETFE-roof for example, analyses the cooling load in three temperature conditions, and calculates the solar radiation heat gained by the ETFE-roof. States a sensitive study about the radiation transmittance, which is the main parameter of membrane structure.
