Open-source environmental analysis plugins for Grasshopper — daylight, energy and comfort simulation.
Why we recommend it
Ladybug and Honeybee put serious building-performance simulation in the hands of designers for free, wired directly into a parametric workflow.
Strengths
- Free and open source
- Validated engines (EnergyPlus, Radiance) under the hood
- Analysis inside a parametric loop
Drawbacks
- Requires Rhino and Grasshopper
- Steep learning curve without building-physics knowledge
