Dear colleagues:
Some of you might be interested in umi a new, Rhino-based design environment for modeling the environmental performance of neighborhoods and cities regarding operational energy use (EnergyPlus), walkability and daylighting potential (Daysim/Radiance). umi is being developed by the Sustainable Design Lab at MIT and can be downloaded from http://www.urbanmodeling.net/.
We gave an one hour overview of umi during a recent symposium on Sustainable Urban Design
Happy simulations,
Christoph Reinhart
