has anyone (especially amongst our german friends) ever had to demonstrate compliance to credit Soc1.4 of the DGNB certification scheme ?
I am particularly interested in the “annual relative useful light” indicator, which seemed to be easily calculated in the old Dialux (https://dialux4.support-en.dial.de/support/solutions/articles/9000112817-how-can-i-calculate-the-annual-relative-utilization-lighting-c)
I’d be quite happy to model this indicator but I can’t figure out what it is actually measuring.
Here are some extracts from the english translation of the DGNB book (Offices Version Core14)
Any idea what 60% of annual relative useful light could mean ?
As a guess I would do the spatial average of the ratio (cumulative lux.hours on each test points / cumulative lux.hours outside)…
Many thanks for your help
