This is an exciting though expected development that the technology behind Ecotect will eventually be integrated right into Autdesk’s core BIM application Revit. Let’s hope this is the first of many integrated building performance tools.

solaraddinUse this Solar Radiation Technology Preview to analyze the effects of solar radiation on various surfaces of your conceptual building model. The add-in uses conceptual massing elements from Revit models and the Autodesk Ecotect insolation analysis engine to calculate the amount of solar radiation hitting the surfaces of the massing shapes. This add-in works with Revit Architecture 2010 Update Release 1 and Revit MEP 2010 Update Release 1.
Go to Autodesk Labs to download the add-in. The archive includes a PDF “getting started” guide.
