Dear All,

Regarding the mandatory requirements of ASHRAE 90.1 for automatic daylighting control.

Our project is a hotel and bedrooms have large windows, so the primary sidelighted area of each room is above 250 ft2. Considering this is a hotel, and that the this type of control in the bedrooms (daylight control, ON/OFF or dimming) may cause some discomfort to the clients, do the daylight control requirements apply?

And in the case that the room has only 1 fixture in the ceiling?

Please note that for all other areas (offices, reception, etc) daylight control will be installed.

Thanks in advance
