Construction

I have issues with timber framed construction. I looked at the following:

ICF's - Has a lot going for them, downside is embedded energy cost of concrete, but this house is intended to last at least as long as the hotel.

SIP's - Looks bit flimsy - we will need to build a boiler room for the hotel, might well try them out here.

AAC - I know it better as the UK trade name Celcon. Not sure why they are not commonly used in the US, no manufacturer I know of in CO.

Floor - most likely concrete for thermal mass. I would prefer accessability for future. But it is a trade off.

Roof Structure- Sips, wood trusses, or steel. My inclination is steel structure with a metal roof, highly insulated.

Heating - Much easier as the demand would be so low. Radiant floor mainly sourced from Solar Panels with a small back up, probably Propane.That really depends on cooking, if we did not want propane for cooking then electric.

Water - we have a well that can be re-used, the design captures water for grey usages.

Ventilation - whole house ventilation and energy recovery.

Insulation - insulated slab, walls R40, roof R70. Biggest issue would be windows, double glazed or triple glazed.

Electricity - we can minimise our demand to make this a Net 0 building. cooking looks like the biggest surge load.But we have the hotel.

Size - I am assuming something like 1250 sq ft, with I master bedroom and en suite, open living area, second bathroom, storage room, entry vestibule, open staircase and one large room that could be multipurpose. Big bedroom, 2 small bedrooms with a divider, work space etc etc.

Cost - do not know, yet. $100 a sq ft?
