Describe the end use of the building: primary residence for a young couple

How did SIP construction help you get this job? The owners wanted high energy efficiency and high performance features throughout the home. They found us through our website and reputation for SIP construction

SIP wall thickness and core material: 6 1/2" EPS
SIP roof thickness and core material: 10 1/4" EPS

Describe the benefits of using SIPs on this project. Did SIPs help save time, labor, construction costs, or energy? The shell of the home went up in 4 days. The owners have decided to add a solar PV package to offset costs and a super tight envelope makes the design of the solar system easier

 

Describe any innovative design elements or structural engineering involved: This is a passive solar home with 24" overhangs to shade the home in the summer and to allow sunlight into the interior of the building in the winter. The building uses clerestory windows to bring light into the interior hallway and North bedrooms. Short roof spans mean simple transverse loading that allows for 8' wide panels and easier installation. The offset rectangles with clerestory roof section add volume through the center of the home that makes the home feel larger than it is.

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. Only list certifications that are completed:

 

HERS Index: -17 (see attachment)
Blower door test results (ACH50): 217 CFM at 50 Pa equates to 1.59
Energy use intensity in kBtu/ft2: kBtu/ft2/yr -11.1

Describe the HVAC system used on the project: Mitsubishi minisplit system with 1-MXZ-3C24NAHZ2-U1 24,000 BTU, 19 SEER outdoor unit combined with 1--MSZ-FH15NA wall unit (15,000BTU) and 1-SEZ-KD12NA4R1 ducted unit (12,000BTU)
These units use a DC inverter technology which makes them very energy efficient and the highest rated in class.

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: R-10 footing insulation to 30" below grade. R-10 under slab insulation combined with R-5 rigid foam above slab and under flooring. This provides warmer and softer floors. Windows are Andersen A series U value .27 SHGC .190

Please list any energy-efficient products or design features, such as lighting, hot water heating, appliances, passive solar: All appliances and fans are top rated Energy Star units. Whole house ventilation provided by programmable Panosonic "Whisper Green" DC fan combined with adjustable balancing intake duct. Most lighting is Power Over Ethernet (POE) low voltage. This system is very energy efficient and gives owners remote control of all lighting. No dish washer is an owner request to save energy. 24' overhangs , siting and clerstory windows are part of the passive solar design.

Were any solar panels installed on the project? If so, indicate the size of the system: 18 Sun Power PV panels installed for a 5.9 kW system that produces 8,358 kWh.
System uses a 7600 Solar Edge Inverter. Federal tax credit for system is -$6,626

 

Please list any sustainable materials or design features not listed above, such as recycled materials, low-VOC finishes, landscaping, etc. (judged only for High Performance Category): We specified on plans that all air and water details were to be from SIPA approved Builders' Guide by Joe Lstiburek. Exterior finishes are installed using "rainscreen" details. Main siding is LP Smart siding with 50 yr warranty over 1/2" treated plywood strips Rainscreen at West and North elevations were a patented system developed by Jim Guffey using heat treated Ash lumber milled for a patented clip rainscreen system. These details add durability to the home

Any additional comments on the project: The owners, Todd and Jaime Wright, did much of the product research and their choices are based on high energy efficiency and durability of materials and systems.
