Honeybee[+] 0.0.3 Release Notes for Grasshopper and Dynamo

August 23, 2017
By Mostapha Sadeghipour Roudsari

Dear Ladybug community,

After more than a year of development, we are very excited to finally have a public release for Honeybee[+]. As most of you already know by now, Honeybee[+] is one of our [+] developments, which is an attempt to make Honeybee platform-agnostic, cloud-compatible, scalable and more flexible for development. It currently consists of a core python library  and the plugin libraries for Grasshopper and Dynamo.

You can download the plugin for Grasshopper from food4Rhino and install the Dynamo plugin from the package manager. You must install the latest version of Radiance to use Honeybee[+].

This current release introduces Radiance-based workflows for daylighting simulations and supports the following simulation types:
  • Point-in-time illuminance (a.k.a grid-based)
  • Point-in-time luminance (a.k.a image-based).
  • Daylight coefficients (both grid-based and image-based)
  • Three-Phase Method (grid-based implemented, image-based to be added soon)
  • Five-Phase Method (grid-based implemented, image-based to be added)

NOTE: There has been a very recent update to the Five-Phase method which was presented at the IBPSA2017 conference last week. These changes have NOT been implemented in the current release. We suggest the users to use the daylight coefficient recipe for annual metrics, sDA and ASE until we apply the recent changes.

While many of you will recognize the first three simulation types above as ones that Honeybee has always supported. Image-based daylight coefficients, Three Phase Method and Five Phase Method are increasingly advanced ways of running annual or time-lapse simulations. Tensor Tree based BSDFs, while supported in Honeybee are not featured in any of the example files. We intend to incorporate this functionality in the near future.  The simulation-methods listed above are based-on empirically validated research conducted primarily by researchers a... There are also some special workflows (which we call recipes!) that make it easier for beginners to use the plugins.
  • Solar access simulation aka sunlight hours (which employs point-in-time simulation).
  • Daylight factor simulation (which employs point-in-time simulations).
  • [Annual] Radiation simulation (which employs daylight coefficients).
  • Annual [daylight] simulation (which employs daylight coefficients)

Energy simulation features are yet to be implemented in Honeybee[+] so, if you’re using Honeybee mostly for energy modeling you should keep using the legacy version.
