Background
This
particular project started in 2011, is an owner-built 55,000ft2 (5110m2) radiant floor
heated multi-purpose building for Fairville Farms of southeast Alberta; operating fluid temperature at an outdoor temperature of -40°F/C have ranged between 100°F (38°C) and 120°F (49°C); with return temperatures floating between 75°F (27°C) and 90°F (32°C) during 30% to 70% load profiles.
The building houses a mechanic shop, vehicle
storage, truck wash, welding shop, carpentry shop, plumbing
shop, field office and water treatment facility.
Peter Sraum, heating technician and
department manager for B.A. Robinson worked with Fairville
Farms on concepts, product brands, preliminary
design and schematics.
We were brought in to do the final
engineering, drawings/specifications and site inspections
for the space heating; we also
provided feasibility study for the engineering and
schematics for the exhaust and make up air systems.
