Fresh air into small office uk requirements with daikin ceiling cassette

hI
I am putting a 35 Daikin ceiling cassette into a small office, theres a max of three people in the office, the office has a window, is there a building/ legal requirement for the amount of fresh air I should bring into the fan coil Site is in England

Many thanks

David

Dont you have the CIBSE guide to work to?

People do pay good money for this info :p

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. :D

Brian i believe he means a 3.5kw unit
