Describe the end use of the building:
Northern California Youth Treatment Center (NCYRTC) Sacred Oaks Healing Center, Indian Health Service. Treatment of approximately 100 tribal youth

How did SIP construction help you get this job?
The center was designed for sustainability, energy efficiency, and environmental design. The client aimed for Zero-Energy and sustainable design elements to gain LEED V$ for BD=C Platinum certification. In order to meet these goals, using SIPS was the only building material available to accomplish this.

SIP wall thickness and core material: 8" exterior wall panels
SIP roof thickness and core material: 12" roof panels
Describe the benefits of using SIPs on this project. Did SIPs help save time, labor, construction costs, or energy?
This project was a prevailing wage project. The use of SIPS substantially kept the labor costs down as the SIPS walls and roof were manufactured in a factory climate. Spline and dimensional lumber was installed in the factory normally done on site to further reduce labor costs. The results created a savings in building time normally HALF of what it would have been if done conventionally. Utilizing 8" exterior panels and 12" roof panels, created extreme energy efficiency of over 65%, giving the project Zero-Energy compliance and Energy Start Certification plus Leed Platinum. This was a must as the project is located in the central Valley of CA, with very hot temperatures in the summer months and cold in the winter months.

Describe any innovative design elements or structural engineering involved:
Two of the buildings have curved walls and roof, to follow the radius of the round house located in the courtyard. The round house has a circumference of over 100' with a 14' radius. All curved radius cuts were figured on the shop drawings for the SIPS and cut during manufacturing. The round house wall panels are segmented to allow for the curved radius of the building.

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:
5-Energy Star, Net Zero Energy Certified, Dept of Energy Zero-Ready Certified, All Energy Star Appliances, Indoor airPLUS certified, Floor Score Certified, LEED V4 for BD+C Platinum Certification and UL Certification

HERS Index: Net positive home with a HERS scor of -19 and a 12.43 kW roof PV Array

Blower door test results (ACH50): 0.047 ACH50

Energy use intensity in kBtu/ft2:
Roof Top Units and VRVs
4250 HWh surplus (net-positive) power (equilvalent to 10,000 miles in an electric car at 2.6 mi/kWh)

Describe the HVAC system used on the project:
All HVAC has ASHRAE 135 Compliance and meet the LEED V4 BD+C Platinum Certification and Zero Energy design

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.
All building materials had to meet Zero-Energy Design and compliance with LEEDs

Please list any energy-efficient products or design features, such as lighting, hot water heating, appliances, passive solar (judged only for High Performance Category):
All building materials had to meet Zero-Energy Design and compliance with LEEDs

Were any solar panels installed on the project? If so, indicate the size of the system:
Solar panels are installed on the project

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):
Solid wood cabinets with low VOC finish, All low-VOC paints, adhesives and sealants, Zehnder HRV, No gas burning appliances in house/ 100% storm water infiltrated on-site. 58% of walkways, driveways and patios are permeable. 80% of the 4.93 acres is undisturbed field grass and native prairie. Less than 3% of the lot is turf grass. Landscaping is primarily fruit and vegetables and native plants. Western Red Cedar trees will provide a windbreak along the northern property line. 20% water use reduction using all WaterSense Certified fixtures. 21% of the lot granted perpetuity to

Any additional comments on the project:
The whole-house battery wiring and Alexa-controlled blinds, lighting, and electronics ensure the home is future-ready for everything Mother Nature brings, while leaving only a light zero-emissions footprint.
