The main goal of green building is to address the issue of how energy savings can improve water efficiency,increase application capacity,and ensure that the region's built and natural environments develop together.The indoor and outdoor environmental performance of green building is the research object of this paper,and the feasibility and rationality of the application of BIM technology in the green building environmental performance evaluation system is discussed.Green building indoor and outdoor wind,sound and indoor light environment green indicators are established,BIM technology is used to carry out parametric modeling through data conversion.3D models within the relevant simulation tools to carry out a variety of performance tests,the use of BIM technology to carry out the assessment of specific aspects and methods are summarized.Based on the proposed evaluation process,the environmental performance of the project,including outdoor wind environment,outdoor acoustic environment,indoor natural ventilation and indoor natural lighting is analyzed and evaluated based on the project case.The results are of great significance to the establishment and improvement of the green building environmental performance evaluation system.
