Abstract

Winter is colder in some parts of China. Simulating the cooling process of buildings in cold regions can optimize the plane distribution and shape design of buildings. This paper presents a simulation calculation method for temperature loss characteristics of assembled buildings in cold regions based on BIM technology, which provides guidance for building planning and design. According to the different wind environments which are too different between different buildings and the strong wind in the building area, the numerical discretization of the wind velocity field is carried out. The strain tensor and spin tensor of the wind velocity field of the building’s outdoor wind environment in the cold region are calculated, to correct the turbulence, and analyze the atmospheric stability of the urban boundary layer structure. Combining with the distribution of wind velocity field, the simulation of building wind invasion and temperature loss process in cold region is realized. The simulation results show that the method is accurate in simulating the temperature process of building’s wind intrusion in cold regions.
