I n t ro d u c t i o n DIVA-for-Rhino is Solemma’s legacy daylighting and energy modelling plug-in for Rhinoceros, a NURBS modeling software. The plug-in was initially developed at the Graduate School of Design at Harvard University and is distributed 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 Metrics, Annual and Individual Time Step Glare Analysis, LEED and CHPS Daylighting Compliance, and Single Thermal Zone Energy and Load Calculations.

Key features: ADVANCED USER INTERFACE – Input and output parameters can be added and removed from components at the click of a button.

SUN PATH DIAGRAMS – Real-time display of sun paths and shadows.

RADIATION MAPS – DIVA’s radiation map tools allow simulation on an annual, seasonal, or point-intime basis.
