What is Ladybug?
Ladybug is an open source environmental plugin for Grasshopper3D that helps architects and engineers create an environmentally-conscious architectural design. Ladybug imports standard EnergyPlus Weather files (.EPW) into Grasshopper and provides a variety of 3D interactive graphics to support the decision-making process during the initial stages of design.
What is Honeybee?
Honeybee connects Grasshopper3D to EnergyPlus, Radiance, Daysim and OpenStudio for building energy and daylighting simulation.The Honeybee project intends to make many of the features of these simulation tools available in a parametric way.

Hi. I've created a building manually, with levels and windows. I turned the geometry into honeybee zones, created the windows with Add glazing tool and now I'm trying to simulate it, but i get this error message: Solution exception:'EPZone' object…Continue
