Please could you be so kind to answer/clarify below.
I am doing a heat loss calculation and on the changing room data sheet i would like the ACH be 8 (conditioned air). I have defined this under thermal design however i believe the ach here is for infiltration (unconditioned). How do i define the ACH coming from outside.
Hi, this is specified in the particular calculation, CIBSE Gain for example. Please find further details in this article.
