Pole building vs. block and stud garage

I put up 40x80 pole building, 1/2 is shop & 1/2 is cold storage. Roof has 2"insulated barrier under roof steel, side walls are 16' clearspan & insulated w/6"batt insulation. Inside shop part is all steel lined like the outside.Ceiling has 12-14in of blown in insulation. Wrapped total shop in plasic, put plastic under the cement for moisture barrier. Have LP furnace that I turn down to maintain 50* and a wood furnace that cooks us out when we're out there working. High,dry & toasty here in the cold,snow belt.
Insulation is probably the cheapest part of the whole building & will really pay back dividends.
