DESIGN OF GREEN ECOLOGICAL PUBLIC ENVIRONMENT BUILDING BASED ON BIM TECHNOLOGY

The application of BIM technology in the design of green and ecological public environment buildings is an inevitable choice, Through the application principles of BIM green ecological public environment building design, detailed research on the practical application of BIM technology is carried out, with the purpose of making better use of the value of BIM technology in the energy-saving design of green buildings, improving the design level of green ecological public environment buildings, and achieving the energy-saving result. In this paper, through the application of BIM simulation analysis software, we design the natural lighting, natural ventilation, spatial pattern, and compare the performance before and after design. The research results show that after the design by using the BIM technology, the annual load of heating, ventilation and air conditioning was reduced from 34280KWh/year to 26350KWh/year, a reduction of more than 23%. The air velocity increased from 0.4m/s to 0.9m/s and carbon emissions have been reduced from 5621kg/year to 4651kg/year.
