BIM models can be enriched with envelope construction and material properties information, schedules and internal loads for creating building energy models (BEM). This presentation summarizes the workflow for performing HVAC load calculations in a BIM authoring environment using cloud-based EnergyPlus design day simulation. The assumptions and best practices for transferring the BIM data for BEM, and the process of transferring the load calculation results automatically to the BIM will be demonstrated with the ASHRAE HQ Building case study. This approach provides architects and designers to perform load calculations without the need to perform any specialized energy modeling tasks.
