Ventilation Planning for Mid-sized Japanese Commercial Kitchens and Calculation Method of Ventilation Rate Using Building Information Modeling

In the design of a commercial kitchen ventilation system, it is very important to maintain the capture efficiency of exhaust hoods and ensure smooth removal of heat, moisture, and odor. The capture efficiency is affected by the kitchen ventilation system and the cooking appliance usage condition. To identify an appropriate ventilation system design method for commercial kitchens in Japan, surveys were conducted as follows.
