Have you played around with flow rates on the delta temp thing?
Thanks for posting the data..and keep posting! It's very hard to find actual data in the wild.
Just as as reference, we saw -35C on Feb 15, and my shop (no heat) dipped down to -14C inside overnight. It does gain some solar heat during they day via the steel roll up door (insulated, and black)...basically a direct air heater. Something to think about as your doors seem to get good light?
Thermal images from a warmer (-15C) but sunny day.
I recently did some work figuring out solar charged wireless temp sensors for SmartThings..let me know if you're interested. It's a very cheap way to gather temp data from wireless sensors with logging from web based data. 100% wireless and because of the $6 solar cell/NiMH replacing internal lithium, the sensors stay fully charged even at -35C temps. About $40 all in including the sensor. Bench test pic:
The sensor is part of door automation so the internal lithium cell pooching in cold temps was not working so well...
