We are pleased to announce that the registration for DIVA Day 2016 is now open. DIVA Days is an annual symposium to discuss the use of DIVA and associated environmental analysis tools in design practice, research and architectural education. More

We're also holding a third annual DIVA Day Student Competition, with a $1500 prize! 


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.

Hi,I'm trying to calculate the potential for glare across multiple spaces in a school, in line with the Green Star Design and As Built (Australia) credit 12.0:For this option, fixed devices must be shown to shade the nominated plane, 1.5m in from…Continue

Is there a way to create a sky of each day of the year at intervals of 30 minutes?

I have a question about the thermal components.I am attempting to run just a single zone model. After a process of trial and error (and checking the .err file) It seems that whenever I try to define a custom schedule or construction on the canvas,…Continue

Why do I get a "solution exception" error ?

Started by CD2005 in DIVA-Grasshopper (version 4.0). Last reply by CD2005 Jul 18. 2 Replies

I get the following error whenever I place any of the simulation components on the canvas:"1. Solution exception:The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)"Continue

Previewing multiple simulation types at once

Started by Scott in DIVA-Grasshopper (version 4.0). Last reply by Scott Jul 18. 5 Replies

I have a grasshopper definition that is running a set of different simulations (radiation, illuminance, annual daylight, etc) that are distributed in a grid.  I'm trying to preview the results of all the simulations at once and run into an issue…Continue
