Envelope air tightness sanity check
Designing a "Contemorary Industrial Passiv Ranch Haus" for DIY build in SW Colorado (CZ6B). Working through data entry in PHPP now and I know the one level elongated ranch style is sub-optimal for PH design. It's 2250 ft^2 (OD) with conc. slab and shed roof. Floor/ceiling/wall envelope area is 6982 ft^2 and volume is about 25789 ft^3. An optimal PH two level cube would have envelope area of 4531 ft^2 and volume about 19125 ft^3. I'm over that by 154% and 135% respectively. Assuming a very good air sealing design and execution- am I going to have a reasonable chance of attaining 0.6ACH50?
Also want to say I've lurked for years here, it's a great forum, thankyou all for sharing your knowledge. I'll have quite a few questions forthcoming.
