Optimizing building scheme design based on building thermal environment simulation by CFD software

Considers the six architectural factors affecting building thermal environment such as the area ratio of window-to-wall, type of the window (heat transfer coefficient), dimensions of the horizontal shade plate, heat transfer coefficient of the external wall, heat transfer coefficient of the roof and dimensions of the room(length∶height∶width). Taking mean indoor temperature, mean PMV, temperature non-uniform coefficient and velocity non-uniform coefficient as the evaluating indexes of indoor thermal environment, obtains the optimal combination of the six factors by CFD simulation and orthogonal experiment method for a better indoor thermal environment for natural ventilated buildings.
