Hello our project is 3 office floors with some spaces destined only for phonebooths wich are only designed for 1 person, however because of the small area the calculations to obtain occupant density result in having to install sensors for these areas, my question is, should I consider these spaces as regularly occupied even though the person who is going to be using the space is only going to use it to make phonecalls sometimes short sometimes long?

I think the phone booths can be considered non-regulalry occupied space, because the occupant spends less than 30 minutes inside on an average.

did you ever get clarification or confirmation on this? We have the same questions.

I've raised the question to the LEED coach of the project, here's her answer:
CO2 sensors: Phone booths are not exempt from these requirements. To meet the credit requirements, projects must monitor CO2 concentrations within all densely occupied spaces, and CO2 monitors must be between 3 and 6 feet above the floor. Densely occupied spaces are those with a design occupant density of 25 people or more per 1,000 square feet, and must be consistent with the densely occupied spaces indicated by the Ventilation Rate Procedure calculations uploaded for IEQp Minimum Indoor Air Quality Performance.

Good to know, thanks for sharing, Carine!
I assume that would apply when the phone booth is a separate room and mechanically ventilated. But that a portable phone booth (like this https://room.com/pages/office-privacy-booths ) would be considered furniture and not subject to the credit requirement. Unless anyone has heard otherwise about how to handle portable booths?
