ABSTRACT

This papers offers a more simple and effective method to simulate indoor and outdoor wind field at the same time, while also exploring the influence of indoor wind field on air conditioning energy consumption. This paper presents an application framework for simulating indoor and outdoor wind field and an air conditioning system based on BIM. Through the BIM software with built-in CFD calculation, the indoor and outdoor wind environment is simulated, and it is found that the outdoor vertical wind field has a certain influence on indoor ventilation. Meanwhile, the air conditioning energy consumption of the building is calculated, and the influence of indoor natural ventilation on air conditioning energy consumption is quantified. This paper provides important guidance for building researchers and practitioners to better align BIM development with green building development in the future.
