Describe the end use of the building: This is a retirement home for Bob and Nancy Springman. It is also a vacation getaway for their children and grandchildren at the Iowa Great Lakes.
Energy efficiency and design flexibility helped with the job acquisition. However, the speed and accuracy that SIPs allowed for in such a tight job site, was the biggest factor in landing the job.
SIP wall thickness and core material: 6 5/8" EPS Type 1 7/16" OSB 5 5/8" EPS 7/16" OSB
The lot that this home was built upon had setbacks of 5 feet along each side of the house to the property line. SIPs allowed for the home to be constructed in fewer steps and in a more "neighbor-friendly" manner. Additionally, the ability to erect a structure and immediately be able to heat it during the winter for subcontractors to work on the mechanics of the house, is a great asset of the SIP construction.
Describe any innovative design elements or structural engineering involved: The second story of the home is an engineered in-room truss with fair separate dormers. Several girder trusses were upwards of 1,000 pounds to carry the load of the upper level ridge beams. These allowed for a completely vaulted second story lounge with 13 foot ceilings. The roof engineering and truss work is second to none!

Describe the HVAC system used on the project: The heating system is composed of a hydronic heating system along with 2 forced air units. The hydronic heat is located in the basement and garage and is powered by a natural gas 112KBtuh, 95% EFU dual boiler. The two forced air units have 58KBtuh and 77KBtuh 96.1 AFUE heating system with a 36KBtuh and 30KBtuh cooling system, respectively.

It was an honor to build this home for a customer who took pride in building an energy efficient home. It was a tremendous experience to lead such a complex and logistically challenging build with the support of Energy Panel Structures (EPS), along the way. Located in a real estate area with a variety of new homes, this one stands out for it's complexity and style paired with the energy efficiencies that only a SIP home could provide
