predicting surface temperatures and condensation (MEEB example 7.5)? i am not totally wrapping my head around this example. the exterior temp is given at 68dF. the interior is given at 36dF. the materials in the wall section are given. what am i calculating? the temperature from INSIDE to outside through the wall section? why does it just so happen that this wall section - once i calculate through it from the inside - gives me 32 degree F which just happens to be the given outdoor air temp?! i don’t get it. ALSO, presumably at some point i would say - well the air can get to this point and i know the air for this climate zone in this worst case scenario during - summer or winter or whatever has this dee point temperature and i can see therefore and QED that air will condense on this surface? so let me move the vapors barrier outward? and also now i will trust this walk seftikn for the humid indoor air conditions and see if nothing condenses on the wall de ruin from the inside? i mean any geniuses really get this topic?
