This is an archived recording of the 2022 online version of the course. The course materials, continuing education credits, and/or professional development hours are not available. This seminar covers the fundamentals of building energy modeling and explains how to use modeling to guide design decisions. Course participants will learn how to integrate modeling into the design process from the programming stage through post-occupancy and measurement and verification. The course explains modeling principles and provides modeling tips related to the building envelope, plug loads, lighting systems, and HVAC systems. The seminar discusses valuable quality control steps and compelling methods for presenting results as well as the appropriate use of modeling throughout the project life cycle and life-cycle cost analysis. The seminar concludes with guidance on model calibration and the use of energy models for measurement and verification. Case studies and links to valuable modeling resources are included.
