Green Building Design Based on Computer Aided Analysis

Abstract

Green building is getting the attention of the construction industry and all walks of life.
However, green building is still in its infancy, its theory is gradually mature, but the backward
technology causes many difficulties in the practice of green building. The purpose of this paper
is to analyze green building design by computer-aided simulation. Firstly, the application of
computer simulation analysis in building is studied, and the task of computer simulation
analysis of green building is defined. Then from two aspects of light environment and wind
environment, this paper studies the computer simulation analysis method of green building, and
summarizes the computer simulation method of BIM performance analysis of green building.
Finally, taking green building engineering as an experiment, the simulation method summarized
in this paper is applied to analyze the design of green building engineering. The experimental
results show that in the indoor environment analysis, given the pressure boundary conditions for
the four windows of the building, the pressure of the south window is + 2.5pa, the pressure of
the west window is + 1.5pa, the pressure of the east window is - 1.5pa, the pressure of the North
window is - 2.5pa. The ventilation situation of the three rooms in North, South and East
directions changed greatly before and after optimization, among which the rooms in North and
south directions changed greatly, and the indoor wind speed increased by 0.1m/s
