How did SIP construction help you get this job?
As an owner builder, I chose SIP construction for its tightness, speed to dry-in and interior comfort. This being our retirement home, we also were looking for very energy efficient home.

SIP wall thickness and core material: 6.5" with expanded poly styrene

SIP roof thickness and core material: 12.5" with expanded poly styrene

Describe the benefits of using SIPs on this project. Did SIPs help save time, labor, construction costs, or energy?
SIP construction allowed us to get it dried in in 13 days from sub-floor to dry-in. This was accomplished with 4 men using 25 ton boom truck. This work was done in the month of January on Whidbey Island. The use of SIP's allowed for phased delivery so that the amount of exposed lumber was kept very small and we were able to keep erected panels edges and openings covered. Being on an island means that there is minimal skilled labor and so the off island crew had to be here much less time. The SIP's gave us a conditioned space almost immediately so that the workers were dry and warm while doing the rough-ins. The cost of providing construction heat was minimal due to the superior insulation.

Describe any innovative design elements or structural engineering involved: The structural bracing ability of the panels for roof and wall construction allowed for a major portion of the west face to have large window openings and a 15' x 10' Nanawall.

Blower door test results (ACH50) (required only for High Performance Category and recommended for residential projects): 1.33 ACH 50

Describe the HVAC system used on the project:
The HVAC system is a complete package of "Carrier" equipment. Including a 97% efficiency gas furnace with a 3 ton heat pump set up to carry all heating until temp goes below 35 degrees. there are four zones that are individually controlled by modulating zone dampers and separate thermostats. there is also a "Carrier" latest generation of air purifier. All ductwork is sheet metal and is interior insulated. A "Navien" instant water heater provides the domestic hot water with a circulating system to reduce water loss at each faucet. This unit also provides the woodshop and garage infloor heating system. All of envelope is conditioned.

Describe any other energy-saving materials used in the building envelope other than SIPs. List U-values of windows used and the U or R-value of any insulation materials:
Windows are U-26 and doors are U-25. All concrete floors are insulated/R-10 and the entire foundation used ICF construction with all floor edges inside for insulating effect. The entire structure is wrapped in VaproShield at the walls and SlopeShield at the metal roof with a rain screen ventilation path at walls and roof to make sure that any vapors that transmit through the wall or roof are able to properly escape.

Please list any energy-efficient products or design features, such as lighting, hot water heating, appliances, passive solar:
All lighting is LED

Were any solar panels installed on the project? If so, indicate the size of the system:
No panels were installed due to location relative to huge protected trees

Please list any sustainable materials or design features not listed above, such as recycled materials, low-VOC finishes, landscaping, etc.:
All cabinet and trim mill-work materials are made from MDF. All of the Stone is manufacture stone. The siding is manufactured from coal ash and polymers.

Any additional comments on the project:
We have lived in the home for 2 months and it is meeting all of our expectations for comfort and heating ease. There are no cold spots and temperature stays constant. During a recent power outage of 12 hours, the interior temperature dropped only 1 degree with 30-40 mph winds in a 12 hour duration.
