To bring this back, here is what I am looking at:
Windows: Original (1976) 2 pane. Are leaky and will be replacing in the next few years
N:80.25/sf E: 50/sf S: 99.5/sf W: 12/sf
Shading probably around 10-15% Ceilings are 8ft most of the house with about 400sf at 12'
Have a poured concrete basement with a crawl space.
Insulation: I would guess R6-10 in the walls. Attic will be about R60 once I blow more in within the month
Blower Door was around 3300-3500 I will be making some improvements soon to hopefully get that down a bit.
Tedkidd, using the site you gave me I am still around 76k for the heat load. Given this info, should I go 60k or 80k furnace? Thanks!!
