Dear all,
Regarding ASHRAE 90.1-2007, section 9.4.1:
"A control device shall be installed that automatically turns lighting off within 30 minutes of all occupants leaving a space, except spaces with multi-scene control, in classrooms (not including shop classrooms, laboratory classrooms, and preschool through 12th grade classrooms)"
1) What do they mean by excluding preschool through 12th grade classrooms? Is this provision of automatic shut-off controls only applicable to University/College classrooms?
2) Are manual control switches in offices, workshops, and auditoriums enough? I can't find them listed in the section of automatic control (9.4.1.2-a)
Many thanks!

You'll have to ask the 90.1 committee at ASHRAE about the exclusions.
Manual controls are enough in all other spaces, see 9.4.1.2b.

Thanks for the question Ghaith. We too find the section 9.4.1 very confusing. We are working on an IT office building in India and have been told that the only thing we need to provide to meet this mandatory requirement is provision for occupancy sensors in conference/meeting rooms and the staff lunch room.
Is the above correct?

Yes those spaces require sensors. Classrooms do as well in all other building types except K-12 schools.
