Describe the end use of the building:

How did SIP construction help you get this job?
There was a requirement by owner to meet certain energy savings. The R value required was achieved by using structurally insulated panels.

SIP wall thickness and core material: 6.5"
Describe the benefits of using SIPs on this project. Did SIPs help save time, labor, construction costs, or energy?
The three dimensional shop drawings provided by Premier saved time, energy, and created a very valuable tool for the assembly of the building. Having numbered panels with installation positions shown on shop drawings was incredibly beneficial while assembling in an arctic environment. The installation was quick and easy.

Describe any innovative design elements or structural engineering involved:
Nothing innovative or creative that pushed the envelope of constructibility. The shape design was more natural with large arcs and framing.

Energy use intensity in kBtu/ft2 (required only for High Performance Category and recommended for commercial projects):
~1000 gallons/month (~30.44 days in ave. month) = 32.85 gallons/day (BTU per gallon of heating fuel = 135,800) = 4461235 BTU = 4461kBTU/day divided by 17300 sqft = .258 kBTU/sqft per day

Describe the HVAC system used on the project:
The heating for the building is hydronic, utilizing primarily radiant floor and cabinet unit heaters. Ventilation and air conditioning are achieved with ducting throughout the building. Three oiled fueled boilers are utilized; one for back-up, and two when outdoor air temperatures are low. Most commonly, one will provide the heat required.

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:
Exterior windows were triple paned and required to meet a maximum U-Factor of .21. The roofing assembly was R-60.

Please list any energy-efficient products or design features, such as lighting, hot water heating, appliances, passive solar:
The building uses LED lighting throughout.

Please list any sustainable materials or design features not listed above, such as recycled materials, low-VOC finishes, landscaping, etc.:
Paint products are low-VOC. Natural landscaping showcasing floral and fauna indigenous to the area was planted around the building.
