SpeedSim-for-DIVA (“SpeedSim”) allows running multiple daylight simulations by using the full processing power of multicore desktops. The number of parallel simulations can be interactively adjusted according to the user needs or the computer capabilities. Then, SpeedSim processes the results making it easy to evaluate the daylighting performance through different metrics.


SpeedSim performs the required simulations for the daylighting modeling files created by DIVA-for-Rhino plug-in in GRASSHOPPER which are generated by using the (“Write Only”) function in the DIVA Daylight Analysis component. It executes the simulations through GRASSHOPPER native components coupled with C# and VB.NET scripting components.


DIVA-for-Rhino is a validated daylighting and energy modeling plug-in for the RHINOCEROS NURBS for Windows. The simulation results generated by DIVA-for-Rhino are validated and published in many specialized international journals.  DIVA-for-Rhino is copyrighted to the President and Fellows of Harvard College. Solemma LLC is the current developer and distributor of DIVA-for-Rhino.
