Hello,
We are having troubles with the language of the credit, with the sDA option, as we are asked 100 lux, but with no indication on the percentage of the time that needs to be compliant.
The normal daylight credit asks of a sDA300/50%, so should we aim for a sDA100/50%, or do we need to read between the lines and understand that "achieving at least 100 lux" means sDA100/100%, meaning a 100% of the time ?
Thanks a lot.
"At least 40% of the area of nonregularly occupied space should achieve at least 100 lux for 10% of the hours between 8am-6pm."
