Hi,
We have a project, where there are large directors' offices. In general, only one person will be working there, but there will be tables with 6 chairs, so let's say additional 6 people can be in this office for some time during the day, from time to time. The office is private office, it is not a meeting room.
If we divide 7 people over the area of the room - we come into "densly occupied space".
We have CAV system there and the amount of fresh air is calculated based on the 7 people in the room, so even if we have only 1 director in the office, there is a lot of fresh air provided.
The system is 100% OA.
Should we provide the CO2 sensors there and treat the space as "densly occupied"?
Many thanks !

Agata, since the zone population is defined in AHRAE 62.1-2007 addendum as the number of people expected to occupy the space under normal circumstances, I would say that the population is 1 and non-densely occupied. You may want to use a reset strategy to save energy on unnecessary OA (sized for 7 people) but that is not applicable to this credit.
