Building information modeling (BIM) is a software-based method to enhance the efficiency of integrated building design including HVAC load calculations. This seminar looks at several different methods of performing HVAC load calculations on the ASHRAE Headquarters building. One method involves performing HVAC load calculations inside the BIM authoring software tool. Another method involves exporting the building information to a standard schema and importing that same information into another vendor's HVAC load calculation tool. This seminar examines the advantages and disadvantages along with the struggles of using these tools to perform comprehensive load calculations.
