Dont you have the CIBSE guide to work to?

People do pay good money for this info

10L/S per person is the recommended ventilation rate but you will have to allow for 3/4 air changes an hour

cassettes hae a 3inch cutout on the corner for fresh air to be distributed via the cassette-but ensure u fit an inline filter

As the room has an opening window, (natural ventilation) mechanical ventilation is not required under Part F

Why does an office with three people in it need 35 cassettes?

Is there something you're not telling us?

No, I'm just impressed with the sales pitch that got that many units for so few people. Well cool.
