I am working on finishing my basement.
Concrete walls with R11 half-wall insulated followed 2x4 wood framing with R13 insulation. Total: 1500 sq ft
Rhvac computes heat loss at Room 1: 16 BTU/hour Room 2: 17 BTU/hour Room 3: 200 BTU/hour
I am guessing Room 3 supply duct - 4" metal duct, Room 1, Room 2 supply -?????
Room 2 to be used as exercise room.
Are you sure you cranked those numbers right? The body kicks out a fair amount of heat on its own. Figure 400 BTU/hour for normal activity and much more if you're exercising.
With those heat loss numbers, I'd be more worried about keeping the rooms cool.
You are right,
I can't read at night....

I am not sure if I sould add additional Sensible load / or ventilation CFMs for an exersize room?
How can I determine return size?
