I'm a curious home owner seeking any input or advice on the following. In particular, I have two questions regarding how loads are calculated in light of my townhome's "shared exterior walls" and a large vaulted ceiling in the upstairs master bedroom.
The house is a middle unit that shares its side walls with two neighboring homes, one shared wall on the north side and another shared wall on the south side. Are these "shared exterior walls" even considered as exterior walls in the load calculation? How much heat loss/gain is coming through these walls?
Lastly, how do vaulted ceilings affect heat gain/heat loss? How do vaulted ceilings compare to normal leveled ceilings in heat gain/loss? How do you calculate such gains/losses for these ceilings?
Thanks. Much appreciated.
