Describe the end use of the building:
This building is on a vegetable farm. The staff areas are a combination of offices, meeting/conference room, knight watchman/living quarters. The Packing area is an area to prepare Vegetables and also has a refrigeration/cooler room. The cold storage is also used to prepare

How did SIP construction help you get this job?
The owner started early on, talking about SIP's construction. He spoke with Lee Bergum our area Rep. and liked the energy efficiency. They were willing to customize our structure

SIP wall thickness and core material: 6" EPS Foam R-26 BC Plywood interiors
SIP roof thickness and core material: 10" Neopor Foam R-50 BC Plywood interiors

Describe the benefits of using SIPs on this project. Did SIPs help save time, labor, construction costs, or energy?
This building was built to stringent structural codes, many, many hold downs, etc. The roof was complex with the overhangs. This was a winter build, once we closed the building in, we poured the heat to it, the frost wasn't hard to get out of the ground. We poured the interior concrete slabs in know time. The buildings energy efficiency was a real plus. EPS used 3/4 " BC plywood for all interior skins, Saved us finishing the interior

Describe any innovative design elements or structural engineering involved:
The main staff area has a timber framed vaulted ceiling, even the packing area has vaulted trusses. There are many, many windows to complement the structure. The exterior roof has two dormers in the staff area and one large dormer in the packing area with again many windows. The east side has a portico roof canopy, timber framed. The west side has a Pergola/entertainment area. Side note- There was a Tornado Sept. 20th that went through the farm, it destroyed the green houses next to this building, but no damage other than a window sash, that we suspect was partially left open.

Blower door test results: 2.72 ACH50 Tight 5000 sq ft

Describe the HVAC system used on the project:
The main source of heat is zoned radiant in floor heat, along with a 95% efficient gas boiler. Also, included is a 4 ton air source heat pump and 4 ton air handler and a HRV air exchanger.

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.

Please list any sustainable materials or design features not listed above, such as recycled materials, low-VOC finishes, landscaping, etc.:
Low VOC Finishes
All main floors are stained concrete with in floor heat

Any additional comments on the project:
From owner:

We are impressed with the quality of material and the engineering of the building. It is a structure that will withstand the test of time. EPS was very attentive to our needs and in designing the building we wanted. The structural quality and engineering, along with the energy efficiency are what make me feel good about our investment, By using SIPs we were able to zone this building easier, we have a produce area attached to living and office areas, easily controlled to their own temperature by using insulated panels, we also incorporated metal clad panels for a large walk-in cooler within the structure
