Are there any guidlines for ventilation in occupied rooms? I've come across various schemes that seem to vary in approach.
Some rooms I have been asked to look at will probably need a\c but I am concerned about ventilation as I feel a\c will not address this issue and despite feeling cooler, the room occupants are still going to fall asleep after lunch...
The rooms are between 5.5 to 3.8 kW cooling duty each and room volumes 63 cu metres (18 occupants max) to 38 cu metres (12 occupants max), all sitting.
One other room has around 11 kW cooling duty, 25 occupants for a 150 cu metre volume.
My gut feeling is fresh air ducted in via a central a\c unit but as building is already up and occupied, and costs tight, it may hit the "How Much!!!! barrier".
As this problem came up as an afterthought after the rooms got thrown up in a hurry, it may be fans in the walls of each room as a starting point and split or multi-split units.
Thanks
Steve
