DIVA 2.0: Integrating daylight and thermal simulations using Rhinoceros 3D, DAYSIM and EnergyPlus

John Alstan Jakubiec, Christoph Reinhart

Abstract: This paper describes a highly optimized design workflow for integrating detailed daylighting analysis using Radiance / DAYSIM with thermal load simulations using EnergyPlus within DIVA, a sustainable analysis plugin for the Rhinoceros 3D Nurbs modeling program. First, the importance of using detailed daylighting models is discussed such that occupant comfort and behavior when operating blinds can be accurately considered. DIVA’’s method of this implementation is then described for a single-zone perimeter office model. Finally, schedules and energy results generated using EnergyPlus defaults are compared to those from detailed analysis in DIVA/DAYSIM. The merits of an integrated workflow are discussed, and it is shown that such an analysis has a significant impact on lighting, heating and cooling loads for a building.
