I have a strange scenario to model and I was hoping I could get some advice: This used to be a whole building built on 1,920 so it is a balloon framing. The homeowner' s apartment is on the second floor, but the front door on the first floor has a little area with a little "receiving" table and that area is heated with a radiator. The basement ceiling has no insulation at all and because of the framing style, it brings a great deal of air into the 2 floor (proved by the blower door)
The entire house is two floors plus attic, but I am modeling a little piece of the first floor, second floor, attic and basement... Any suggestions on how to do this?
Your comments are greatly appreciated,
