How did SIP construction help you get this job?
The client came to us wanting a house that was superior in energy efficiency, indoor air quality & with a modern design. SIPs were a natural fit for a tight envelope and to achieve the air tightness needed for great indoor air quality. The client also loved the idea of the additional strength that SIPs provide

SIP wall thickness and core material: 4.5"

SIP roof thickness and core material: 8.25"

Describe the benefits of using SIPs on this project. Did SIPs help save time, labor, construction costs, or energy?
Ferrier Custom Homes is a small volume, specialist among builders. As a result, we have not been able to obtain lower costs from our framing crews to erect our SIPs. The benefit from using SIPs was to fulfill the clients desire for a more energy efficient home with greater air tightness as he has allergy and asthma problems. The architect was able to take advantage of the large interior volumes the SIP roof panels provided for these vaulted ceilings.

Describe any innovative design elements or structural engineering involved:
The design is a new “Mid-Century Modern” style structure complimenting the adjacent context of 1950’s traditional homes. The home was positioned on the lot to maximize the size of the private rear yard. A short cantilevered portion of the second floor projects slightly over the front building line. This provides more space for the upper bedrooms and a subtle sculptural feature expressed on the front elevation of the home.
A series of large low sloping mono-pitch roof planes provide maximum flexibility for placement of solar arrays on the Southern and Western exposures. The surface color of the roof is white to reflect the maximum amount of sunlight possible and minimize heat gain. The SIP panel roof planes also provide sculpted interior volumes for visual interest throughout the home.
A large covered Rear Porch area separates the main structure from the Garage area. This Porch acts as a natural breezeway and provides comfortable indoor/outdoor living space directly accessible from the Living Room and Master Suite, and boasts an outdoor kitchen. Large sliding glass doors in this area, protected from any direct sunlight, connect the interior and exterior Porch areas visually expanding the size of available living space. This also allows maximum air flow during our more moderate seasons when the Owner expressed that he would turn off the AC and open his windows & doors for air flow. The large sliding glass doors open for great air entry and the design creates a “low pressure” area that naturally draws air into the house and out the north windows on both lower and upper levels.
Passive solar design was discussed early & often, and affected window layout, overhang depths & shading considerations. Living in place elements incorporated throughout first level of home. A steam shower was incorporated into the master shower, which helps the homeowner's respiratory sensitivities.

Any additional comments on the project:
Homeowner testimonial: "The zero-energy ready home has given me a superior home-owning experience. Being an asthmatic, the various air sealing measures offer dual benefits of having tightened the house to improve air quality while reducing costs. Due to energy conservation, quality construction, and innovative technologies, I can rest easy knowing I have made the right choice."
