In this presentation will we review the state of Autodesk simulation software, Insight and how it compares to the traditional model workflow of Daylighting with Radiance. Insight is a cloud-based analysis tool which evolved from a previous Autodesk software, Green Building Studio, and focuses on energy and environmental performance as well as improving BIM workflow integration. Insight is an overlay type of integration with Revit models of various detail from conceptual massing to detailed Architectural models so that design decisions can be analyzed to measure the impact on the overall building performance through the design process. Insight simulation and analysis focuses on the following three areas: energy, daylighting, and solar analysis. We will review in detail the workflow, types of simulation engines, simulation parameters, and results analysis for Insight's Daylighting (via Revit Model) which will then be compared against Radiance models (SketchUp).
