Describe the end use of the building:
This house may eventually become the guest house, with a slightly larger "main house" planned just below it on the same property. The owners are enjoying the smaller home, and the relaxed lifestyle that comes with it, that they are considering not ever building the "main house", or at most making it about the same size as this one, but only one bedroom, with larger great room and kitchen.

How did SIP construction help you get this job?
Zero-Energy Construction was a primary requirement for these customers, and SIPS construction is by far the most cost-effective way to get there from here.

SIP wall thickness and core material: 6-1/2" SIPs with Neopor fill
SIP roof thickness and core material: 10-1/4" SIPs with Neopor fill

Describe the benefits of using SIPs on this project. Did SIPs help save time, labor, construction costs, or energy?
This home was designed with SIPS in mind, and the heights of walls, pitch of the roof, and spans of roof SIPs were all optimized for passive solar gains, active PV system exposure, and to fit within the parameters allowed by the NTA report for Premier SIPs. There would have been no way to stick-frame this house for less than what we spent on SIPs construction.

Describe any innovative design elements or structural engineering involved:
The home has a very large feel due to the cathedral ceilings, but we dropped an 8' ceiling over the bathroom, giving us a nice large attic space in which to house the air-handling equipment, and provide the owners with lots of "free" storage area. We have also learned that even though the engineering does not require them, using an I-loist spline between your 8' wide roof panels makes the roof go together much easier, because the panels are much stiffer when you have two guys up there bouncing around on them trying to pull the roof panels together

Please list any certifications the project received, such as ENERGY STAR, LEED, National Green Building Standard, WELL, Passive House, Green Globes or local green building programs:
Energy Start, Indoor Air Plus, USDOE Zero-Energy Ready home

HERS Index: 16
Blower door test results (ACH50): 0.89
Energy use intensity in kBtu/ft2: 27.04

Describe the HVAC system used on the project:
Because the heat loss to the outside is so small, a single-head ductless heat pump, located above the entry door in the great room, is able to heat the entire unit, with the bedrooms remaining just a couple of degrees below the great room.

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:
Vinyltek Triple-glazed windows were used, with U-values ranging from .16 to .21, depending on the type and size of window. 4" (R-20) foam insulation was used under the entire slab, and 2" (R-10) perimeter insulation was used to isolate the earth under the house from the surrounding surface air temperatures.

Please list any energy-efficient products or design features, such as lighting, hot water heating, appliances, passive solar:
All lighting was 100% LED. All appliances were EnergyStar. Passive solar was designed in, with the south-facing window optimized for passive solar gains. Summer cooling is managed by the thermal mass slab, and generous roof overhangs limiting the ability of the summer sun to penetrate the high-solar heat gain windows. Those same windows provide much of the required heating during the winter months.

Please list any sustainable materials or design features not listed above, such as recycled materials, low-VOC finishes, landscaping, etc.:
The owners sought out and purchased a recycled door package for all their interior doors. 100% of the paint and adhesives used were zero-VOC products. The landscaping was 100% native species, in keeping with the requirements of the Ebey's Prairie National Historical Reserve requirements

Any additional comments on the project:
The architectural features of this home were required to meet the design guidelines of the Ebey's Prairie National Historic Reserve. This project is an outstanding example of how modern building materials and methods can combine with a very traditional design to produce exemplary performance results
