SFR = Group R-3
House is elevated on concrete pilings / all supporting exterior columns/beams are concrete
All floor systems are steel web trusses with 4.5" concrete topping
Stairs between floor levels are wood
NO interior load bearing walls - all loads carried on steel beams
All exterior walls are 12" thick ICF (8" core)
Exterior of exterior walls are covered in 3-coat stucco
All exterior decks are concrete and steel truss with underside covered in treated plywood then covered with stucco
Garage ceiling below is 5/8" type X gyp
Storage enclosure in garage is 5/8" type X gyp (for stair access / elevator)
Interior beams supporting the spans where needed are heavy red steel.
Interior columns supporting the red steel beams are also red steel
All undersides of floors/trusses are sprayed with fire-retardant spray foam - open cell polyurethane.
Interior ceilings is planned at 1/2" gyp but could be 5/8" or 5/8" type X if it makes a difference.
Interior walls are 1/2" gyp
Interior walls (all) are insulated with R-13 or R-19 fiberglass batts where appropriate for size
Interior of attic is spray foamed and then covered with radiant barrier
Roof trusses are made of fire-retardent treated wood, covered with 15/32 decking, covered with peel-n-stick barrier and metal standing seam roof (underside of roof is also spray foamed.
What is the proposed building classification?
What could it be?
What would make it better/tighter?
Would steel studs in the interior make a difference in classification?
