For cooling there are the double doors on the back and the ports on the side. The back is toward the South and the side is on the West. We have a prevailing southwest wind here, so I will get a little breeze plus the use of a heavy squirrel cage fan that I can aim where I am working.

Heating is almost impossible. My existing shop is also a non insulated metal building and whatever heat you pour in just goes right through the metal. I have a few radiant heaters that I aim where I am working. I also have a Dearborn. I plan on building a wood stove before next Winter since I have an unlimited supply of firewood that only costs the fuel for the chainsaw.

So, mostly I will be roughing it. In the past my work gets limited to what MUST be done during July, August and January,February.

Have a great day,
