Describe the end use of the building:
Replacement of previous 5 bedroom residence destroyed by forest fires.
How did SIP construction help you get this job?
Energy efficiency, speed of construction for rebuild and fire resistant properties.
SIP roof thickness and core material: 12" GPS core Platinum SIPs (with 7/16" OSB top and bottom skins) 6,656 sqft.
Describe the benefits of using SIPs on this project. Did SIPs help save time, labor, construction costs, or energy?
Energy efficiency, healthy indoor air quality from large panels and reduced air infiltration (family has sensitivities to different building products, so they hired an indoor air quality expert to help select products. Report for this attached.) Speed of construction for rebuild and fire resistant properties, also contributed to the selection of SIPs.
Describe any innovative design elements or structural engineering involved:
Seismic zone D, this and heavy snowfall area made total roof loads critical. Especially given rebuild of existing roof overhangs and double cantilever eave/rake overhangs (details attached). Simple engineering allowed large panels to carry the load for the full large roof without an extensive truss system.
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:
Indoor Air Quality certification. Additionally, they consulted German Phd Chemist (interntional expert on SVOCs) about strategies for sealing the underside of the SIPS roof without any toxicities.
