[Radiance-general] VI-Suite v0.4

[Jan Wienold]

Hi Ryan,

it looks really cool.

Are there already plans to include evaluations according to the new 
European Daylight Standard prEN17037 "Daylight of buildings"? So far it 
is still a draft, but if all goes well it will become a standard at the 
beginning of next year.
This would mean including CBDM for the daylight provision (a bit other 
definition than sDA),  calculate the sunlight exposure (in contrary to 
the US, the European standard recommends to have access to direct 
sunlight) and calculate the protection from glare (CBDM glare evaluation 
based on DGP).

For an implementation of the CBDM glare analysis I can offer my help.

Cheers
Jan

As Blender attempts to be the Swiss Army Knife of digital content creation so the Vi-Suite tries to be the Swiss Army Knife of building contextual and performance evaluation. It is indeed free and open source and is released under the same license as Blender (GPL v2).

There are also a number of nephews and nieces (sun path, wind rose, shadow mapping, sky view factor). The VI-Suite is also currently pregnant with FloVi (OpenFoam).

Blender mesh objects are used to define the sensor points for rtrace numerical calculations and LiVi visualises the results by colouring these meshes. The integration with Blender is generally pretty deep. Blender's text editor can be used to manually edit Radiance input files and Blender cameras are used for rvu viewpoint etc.
