Daylighting
This criterion is based on two main points:
1. The provision of daylight has been designed in accordance with national best practice daylighting guides.
2. At least 80% of the net leasable office floor area is adequately daylit.
“Adequately daylit” is defined according to daylight luminance (200 lux for 2650 hours per year on average) or
an average daylight factor, depending on the latitude of the building.
A uniformity ratio of at least 0.4 or a minimum point daylight factor also has to be achieved.
