A Simulated Study of the Influence of Wind Projecting Angle on Energy Consumption of Residential Building Clusters

Abstract

In the study of cluster thermal environment, the projecting angle of wind against buildings exercises vital influence on the environment. This thesis, taking Xi’an region as a representative city, conducts a study of how different wind projecting angles influence the thermal environment by means of the simulator program of energy consumption. By sequentially alternating the included angle between the orientation of building cluster and wind direction, it sets up different arithmetic example models which can meet the requirements of various seasons. It also quantitatively expounds the impact of wind projecting angle on energy consumption of buildings with the annual minimal energy consumption of buildings as its basis. The research has worked out the following recommended plans about the orientation of cluster distribution in Xi’an region. The building is at its lowest level of energy consumption when its wind projecting angle is 30 degrees. Its energy consumption is relatively stable when its wind projecting angle is 45 degrees or when it rotates anti-clockwise within 15 degrees.
