Extent of daylight simulation model

NC-v4 EQc7: Daylight
posted by Benjamin Weise on Oct 25, 2019, 9:12 am

Hi there!

we are about to undertake the daylight simulation for a 50.000m² building. The way we understand the credit language, the whole building is to be simulated, except non regularly...

Project with frits in some rooms

NC-v4 EQc7: Daylight

For daylight credit, do the frits suffice as sun shading? 

Or would these rooms of the building not qualify for the daylight credit or just be hindered during a simulation?

Dear,

We have made several daylight simulations with option 2 for different projects. So far, it seems nearly impossible to achieve even 1 point for this credit, mainly due to the 3000 lux...
