For lighting levels which have been established by the American National Standard A11.1-1965, R1970, Practice for Industrial Lighting would this qualify as an exception as listed by ASHRAE 90.1 200

Can vacancy sensors be used in place of occupancy sensors in appropriate spaces? Vacancy sensors, like occupancy sensors, will turn the lights off when the room is deemed vacant.

Dear all, I am working on a CI Library renovation and we have an existing cellar where the majority of the services exist (IE. Boilers, IT Servers).

Hi everybody, My team and I are working on a CI project (office floor) where the tenant has installed occupancy sensors for up to 75% of connected lighting load.

Our project includes an office area and a warehouse area. The office area will have occupancy sensors for each office, bathroom, corridors, etc. The warehouse will not have sensors.

Total lighting load for project space under EAc1.2 would be the same as connected lighting load under EAp2?

For compliance with the "Daylit Controls" we are placing sensors in all perimeter of the offices within 4,5m of the windows, at the high of the ceiling.

Can we still include private offices that have occupancy sensor controls. Under the drop down space type menu, it only mentions shared office.
