Honeybee supports detailed daylighting and thermodynamic modeling that tends to be most relevant during mid and later stages of design. Specifically, it creates, runs and visualizes the results of daylight and radiation simulations using Radiance and energy models using EnergyPlus/OpenStudio. It accomplishes this by linking the Grasshopper/Rhino CAD environment to these engines. It also serves as an object-oriented Software Development Kit (SDK) for these engines.
Run illuminance simulations with IES light fixture definitions to ensure that electric lights are properly sized for given tasks. This can also be used to estimate outdoor light pollution.
Model a wide range of passive strategies including natural ventilation, earth tubes, evaporative cooling towers, high thermal mass spaces, ventilation chimneys, vented double-skin facades, and virtually any shading geometry.
Model a wide range of HVAC strategies including radiant slabs, chilled beams, VRFs, ground sourced systems, heat recovery, custom ventilation schedules, and optimize all of your supply temperatures with parametric studies. If you still find this list limited, you can model virtually any HVAC system using Honeybee's support for OpenStudio measures.
