We have a project in question that is DMV office and vehicle inspection station. The vehicle inspection lanes side of the building are approximately 50% of the total project square footage. The inspection lanes have a series of drive through lanes with 14' doors that remain open throughout the 12 hour operating period each day. Each lane is designed to accommodate any potential vehicle including commercial trucks and buses which drives the door sizes. This creates a scenario in which the full length of both entry and exit doors are open during occupied operation hours hours. The floor will have radiant heat for freeze protection and pre-manufactured operator booths that are heated and ventilated. In addition there is a series of testing equipment to include larger equipment and motors to test brakes, etc. What is the proper approach to take in the modeling of the overall building to avoid an undue hardship being placed on the model due to the open inspection lanes?
