I am trying to use Honeybee[+] to run a daylight simulation using the Solatube BSDF files and wondering if anyone has experience working with these? My results seemed much lower than I expected so I tried using Honeybee[+], Honeybee, and DIVA for comparison. I am wondering if I have an incorrect setting with Honeybee because the DIVA results seem much more in line with my expectations and all three models are using the same geometry, materials, etc.
Below is information on the BSDF files from solatube with some instructions:
Here are my results for an illuminance calculation from DIVA (left), Honeybee+ (center), and Honeybee (right). These were attempting to replicate a report from solatube indicating that 25 devices would produce a workplane illuminance of 112 fc, so even DIVA is significantly lower than what they are claiming.
Below is a dropbox link to download my files for reference as well as a sample report from Solatube. Any help would be appreciated!
