Graham,
30 deg C is too hot? I supposed it all depends on the humidity. Here is
the desert, that is perfect outside weather.
Are you in a position to spend money? (I know, Bad question). I've had a
passing interest in an air exchanger for my house. (I haven't purchased one
yet because energy had been so cheap, maybe I should start looking again).
With super insulated homes, air exchanges occur so seldom that there is
danger of asphyxiation, not unlike your coating room. However, exchanging
air defeats the point of super insulating a house. Thus, air exchangers
that transfer the conditioning of hot or cold air from the house to the
incoming air from outside have been developed. I have seen some that are
passive without moving parts except for the fan to move the air. I don't
know if the technology has been developed for industrial use; nor have I
performed enough research to convince myself that it works; but it might.
(You will have to do the research).
Another passive technique is to put the building in the shade, artificially
of course. Imagine hundreds of picnic umbrellas on your roof and you will
get the picture. Naturally, building a suspended roof over your existing
roof will cost dollars, or in your case, pounds.
Or....
Can you make your high exchange rate just in the areas that need it. For
example, hand solder stations sometimes have individual vents just at that
station to capture the fumes, rather than drawing the whole factory air
away.
Or...
6:00..way past quitting time...sorry I gotta go
