Hello everyone,

I am working on a hotel project where we  have a large hotel lobby which consists of the following sub-spaces:

- Single height seating area on ground level

- Double height bar area on ground level

- Single height seating area on the mezzanine level above the ground level seating area

To give you an idea of the layout and how the aforementioned spaces are connected to each other, as you enter the hotel via the main entrance on the ground level on the right hand side is the bar and on the left hand side is the seating area having another seating area straight above it (mezzanine level). The bar and the ground level seating area are clearly divided by the building's core area (stairs, lifts), however there is a 11m long and 2.5m wide corridor between, with no physical walls dividing the two spaces. The same applies regarding the mezzanine level seating area and the double height bar, i.e. they are not fully enclosed spaces.

We will have only one AC controller in the bar area to control the temperature on the aforementioned spaces. My question is whether the above spaces can count as one single room (in this case we comply with one multioccupant control) or must be separate individual spaces and they would all require individual multioccupant thermal comfort controls?

Many thanks in advance,

Aris
