Describe the end use of the building:
Private residence for the property owner.

How did SIP construction help you get this job?
I was retained after responding to an online SIPA inquiry request. The property owner had researched SIPs and was wanting to work with someone with SIP design experience. My primary practice is focused to SIP / high performance construction design only.

SIP wall thickness and core material:
House: 6.5" overall with 5.5" core. Garage: 4.5" overall with 3.5" EPS core

SIP roof thickness and core material:
House and Garage: 10.25" overall with 9.25" EPS core

Describe the benefits of using SIPs on this project. Did SIPs help save time, labor, construction costs, or energy?
SIPs assisted the project to achieve the level of energy efficiency and durability the homeowner wanted. This home was designed with "aging in place" (Universal Design) in mind as being the homeowners last place to live. Having low energy costs with reduced mechanical sizes and low maintenance were important concerns of the homeowners to be able to sustain the remaining years as well as accessibility to the living space. It also helped having less subcontractors and material on-site on a tight lot since the project coordination on-site was preformed primarily by the homeowners.

Describe any innovative design elements or structural engineering involved:
Extensive southern exposure with venting (awning) clerestory windows and overhangs designed for shading in the summer (passive solar and ventilation) while providing reflected indirect lighting in the main living space. Overhangs were designed and constructed using embedded members within the SIP roof and T&G planking providing a thinner overhang profile. Basement constructed using insulated precast concrete panels (Superior Walls) providing continuous insulated envelope from basement slab to roof peak. Insulated root cellar / storm shelter under front porch. Rainwater falls into a gravel french drain which is collected in a cistern for reuse. The gravel pre-filters the water.

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 (required only for High Performance Category and recommended for residential projects:
RESNET Registered (confirmed) 48. See attached reports.

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

Energy use intensity in kBtu/ft2 (required only for High Performance Category and recommended for commercial projects):
10.6 Btuh/ft2 heating (@47°F) / 10.38 Btuh/ft2 total cooling

Describe the HVAC system used on the project:
Main level is conditioned using ground source heat pump, 4.8 COP / 24.1 EER (Geothermal System) while basement is naturally ventilated using casement windows and double man door with no heating or cooling unit installed. Basement and main level separated by insulation barrier. Main level and Attic are mechanically ventilated with Energy Recovery Ventilator (ERV) providing 70 CFM continuously. System designed by ACCA HVAC Design Consultant (see attached Manual Calcs).

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. (judged only for High Performance Category)
   - Insulated precast concrete foundation walls (Superior Walls) R-Value: 12.5
   - Sunrise Windows Omega 12 (EnergyStar) U-Factor: 0.26; SHGC: 0.19 (insulated frames
     with integral brick moulid for tighter installation).
   - Energy Star shingles, prepared for solar panel installation.

Please list any energy-efficient products or design features, such as lighting, hot water heating, appliances, passive solar (judged only for High Performance Category:
   - 100% LED lighting.
   - Passive solar heating and ventilation.
   - Geothermal heating and cooling.
   - Rheem Marathon electric water heater with geothermal assistance.
   - Natural daylighting.           
   - Rainwater harvesting design. Text

Were any solar panels installed on the project? If so, indicate the size of the system (judged only for High Performance Category):
No solar panels installed at final inspection, however the project is solar-ready. Panels anticipated to be installed within the next year. South roof plane exceeds area needed for Net-Zero.

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):
   - All low-VOC interior finishes. - All trim and cabinets built using birch harvested from building
   - Rainwater harvesting system collecting filtered water from foundation drain tile.
   - No rain gutters. Runoff falls directly into french drain (naturally filtered) collected by rainwater
     harvesting system usable for potability.

Any additional comments on the project:
   - SIP walls and roof installed by SIPA Member Al Cobb (Panelwrights)

   - SIP engineering and project consultant engineering by Tom Moore (Pinnacle Engineering)

   - Average monthly utility bills (all electric energy) per month (12 months)

Heating = $10.58/month; Cooling = $11.50/month; Water Heating = $12.83/month Lights/Appliances = $64.50/month; Service Charges = $8.00/month

Total = $117.33/month.
