How did SIP construction help you get this job?
Big Sky R-Control SIPs are one of the most air-tight and well-insulated building systems available, making them an inherently green product. An airtight SIP building will use less energy to heat and cool, (energy efficiency), allow for better control over indoor environmental conditions, allows for fewer allergens/mold and reduce construction waste. In addition, timing was everything in the construction as this area has snow  months out of the year. So speed and efficiency were a top priority.

SIP wall thickness: 6 1/2"
SIP roof thickness: 12 /14"

The benefits of using SIPs on this project:
SIPs offered benefits at all levels of the building design and construction process for architects, designers, builders, and the residents or occupiers of the building.

Panels have many uses, including:
Internal and external walls, floors, and roof surfaces.
Roof trusses can be eliminated, which allows living space beneath the roof.
Structurally superior to traditional wood framing—stronger and less susceptible to shifting.
50 percent more energy efficient than those constructed with traditional framing.
Equivalent U-values can be achieved with thinner walls.
Can be combined with other building materials, such as brick, block, stone, tiles, slate, wood, steel, and glass.

Blower door test results:
2.05 ACH50

HVAC System:
HVAC consists of radiant floor heating. No A/C as the home is at 11,450 feet in the highest neighborhood in the US and snow covered about half the year.

Additional sustainable materials or design features:
Home has lots of beetle-kill pine used for flooring, soffits, closet doors. Good use of otherwise wasted materials.  House is heated with wood burning stove utilizing tree felled by avalanche.

Additional comments:
Instant hot water and everything but the lights run by natural gas. Engineered for 100 psf snow load. I used a lot of tongue and groove beetle kill pine for the flooring, soffits, and closet doors which is an Eco friendly wood. All cedar siding. I am keeping the home warm with a very efficient wood fireplace that runs constantly using dead and downed wood harvested from avalanche chutes on national forest land.
