September 30

University of Toronto



Register now for DIVA Day 2016! DIVA Day is an annual symposium to discuss the use of DIVA and associated environmental analysis tools in design practice, research and architectural education. We're also holding a third annual DIVA Day Student Competition, with a $1500 prize!  Due date has been extended to September 3.


What is DIVA-for-Rhino?

DIVA-for-Rhino is a highly optimized daylighting and energy modeling plug-in for the Rhinoceros - NURBS modeler. The plug-in was initially developed at the Graduate School of Design at Harvard University and is now distributed and developed by Solemma LLC. DIVA-for-Rhino allows users to carry out a series of environmental performance evaluations of individual buildings and urban landscapes including Radiation Maps, Photorealistic Renderings, Climate-Based Daylighting MetricsAnnual and Individual Time Step Glare Analysis, LEED and CHPS Daylighting Compliance, and Single Thermal Zone Energy and Load Calculations.
