Autodesk Project Vasari

Project Vasari supports performance-based design via integrated energy modeling and analysis features. Project Vasari can be used in conjunction with Ecotect Wind Rose analysis to dynamically simulate the impact of wind speed and direction on a projects. This prototype plug-in provides a simplified “virtual wind tunnel” that allows designers and engineers to run computational fluid dynamic early in the design process.
