How does ceiling height affect room volume / heat losses?
I have looked at the back end of the calcs and I can see the following formula to work out infiltration losses:
Infiltration heat loss = F2 nV (tr - to) / 3
How is the volume is the above formula calculated? (I assume this is what affects the heat losses in terms of the ceiling)
Does the ceiling height determine the volume of the room?
For example, we have a 1 by 1m room, that is 2m tall.
In the first instance there is no ceiling applied, therefore the volume is 2m^3?
In the second instance there is a ceiling at, say, 1m, therefore the volume is 1m^3?
Please confirm if my understanding is correct.
Thanks for raising this, I am currently looking into your issue, will get back to you shortly.
Good afternoon, I assume you are referring to uppermost rooms under the roof/ceiling - ie the results of the function below?

Hi Shane yes I can confirm I am
Thanks Toby, just wanted to make sure we were on the same page.Yes indeed, this will adjust room heights/volumes accordingly. If you wished to confirm this in your rooms you can do so by using the Print and Schedule functions, eg:
Hope that helps?
