Ladybug and Honeybee for Building Performance Design

In the past I have criticized the lack of climate/predesign and daylighting analysis tools in Vasari. So it was with great surprise that I recently learned about Ladybug and Honeybee, some recent projects developed by Mostapha Sadeghipour Roudsari, Chris Mackey and Saeran Vasanthakumar.

The tools address the 2 most significant weaknesses encountered when using Vasari:

  1. Predesign tools/climate analysis – By which I mean the ability to explore the information contained in a weather file in a meaningful way to explore design possibilities that are appropriate for a given climate.
  2. Daylighting simulation – Integration of a simulation engine for daylighting/glare analysis.

Number 1 has been on my wishlist for a while and despite feedback to the development team [1, 2] I have seen no improvements. Number 2, is showing a tiny bit of promise with recent Autodesk Labs developments.

So with Ecotect being effecctively retired by the release of 2015 products (Autodesk supports up to 3 releases back), the time is ripe for some new development! While I still love the Revit platform, some basic tools designers need for building performance just aren’t there and have driven me to explore the world of Rhino3D/Grasshopper. I encourage you to check out Ladybug and Honeybee, providing new integrated workflows to design better buildings.

UPDATE: 4/4 Just came across this from LMN Architects showing that there definitely is a need for more climate analysis tools.
