Diva Day 2016

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.

Point-in-time illuminance

Started by Simona Esposito in DIVA-Rhino (version 4.0). Last reply by J. Alstan Jakubiec yesterday. 1 Reply

Hello,I'm trying to run a simulation of illuminance by changing the values of the weather file (.epw) but I'm not sure I do it correctly. What values of weather file DIVA uses to do this type of analysis?Thanks.Continue

HelloHow can I run a parametric study to change the glazing type of the window and see the impact of change in Visible Transmittance? I would like to know if it is possible to do so in Honeybee for grasshopper plugin. ThanksLadanContinue

Maximum Luminance in Glare Visualizations

Started by Kit Elsworth in DIVA-Grasshopper (version 4.0). Last reply by Kit Elsworth on Thursday. 6 Replies

In addition to using DGP for glare analysis, I would also like to simply test the contrast ratio of brightest to darkest spot on the falsecolor glare visualizations to compare to the IESNA recommended contrast ratios (3:1 to 30:1). Using the Lmin…Continue

Radiation Map - Hourly Simulation Error
