Orientation correction factors to the heat transfer coefficient for energy efficiency building envelopes in Tibet

The current energy efficiency design standard for heated residential buildings contains the heating energy index but misses corresponding and complete basic parameters for energy calculation for Tibet, i.e. no orientation correction factors defined for calculating the heat transfer coefficient of building envelopes. Based on the typical year weather data of Lhasa, dynamically calculates the heating load for building envelopes using the response coefficient method, finds the orientation correct factors, and proposes a variable factor correction method for south-facing windows.
