The LEED v4 Reference Guide has additional guidance on how to classify spaces and how to determine which spaces are included for each IEQ credit. For this credit, daylight modeling or measurements must be conducted in all regularly-occupied spaces, which is any place where people spend an hour or more per day conducting typical activities. Regularly-occupied spaces that are only used for video conferencing, like teleconfencing rooms or dedicated video conference rooms, can be excluded from the credit. Auditoriums must be included but have a lower acceptable illuminance level.
