Application on smoke prevention and exhaust system design of intelligent BIM based on a domestic self-developed software

To enhance the design quality and collaborative efficiency of HVAC engineering, this paper proposes an intelligent BIM design process based on the self-developed software EasyBIM. Taking smoke prevention and exhaust systems as an example, the study explores the dynamic association logic between model data and calculation parameters in aspects such as air volume calculation, equipment selection and information extraction. It demonstrates the positive impact of automated data transmission on design quality and efficiency, offering a methodological reference for the full-process digital design of the HVAC discipline.
