Influence of windowwall ratio on annual energy consumption for heating and air conditioning in residential buildings

Dynamically simulates the annual energy consumption for a typical residential building in Shanghai using DeST software, and studies the influence of windowwall ratio in different building orientations. The results show that the total energy consumption for heating and air conditioning will increase with the greater east (west) or north windowwall ratio and that the total energy consumption will be reduced with the greater south windowwall ratio on condition that window shading and night ventilation in summer.
