Analysis on problems existed in simulation of indoor thermal environment for residential buildings

With an unconditioned residential unit in Beijing as the test object, simulates the indoor temperature, and compares the simulated and measured temperatures. As a result, the indoor thermal environment is very sensitive to the factors of sky radiation, exterior window shade, indoor temperature of neighboring rooms and natural ventilation conditions. During the use of DeST software, the actual variation of the above factors should be described to match the simulated and test results well.
