FlucsDL - Outside reflectance of an exposed floor
Posted: Thu Oct 17, 2013 9:42 am
Hi all,
I'm using FlucsDL for a daylighting analysis on a project to assess the impact of a 5m long overhang on a facade. In fact, the 2nd floor of the building is wider than the 1st floor, meaning that the 2nd floor represents the overhang for the 1st floor's facade.
The idea for the project would be to install a mirror under the exposed slab of the 2nd floor in order to enhance the natural light entering the 1st floor.
So in FlucsDL, I went to "Assign surface properties" then "Groud/Exposed floor" where I wanted to change the outside reflectance of that slab to set 90% (for the mirror). The problem is that this option is enabled.
Does it mean that FlucsDL doesn't take into account the reflection from an overhang? Or is there a default value that cannot be changed?
Thanks in advance for your help,
David
