In reply to the discussion: After protest, Amazon workers finally get AC (some work in 110 degree temps for $11/hr) [View all]reflection
(6,286 posts)have heating, usually from unit heaters spaced in a fashion to wash the exterior walls. Sometimes by gas-fired packaged units. Sometimes by infrared tube heaters. A smaller percentage have cooling, but that number is rising steadily every year as the cost goes down. Even in the South it gets cold enough in the winter to require heating, especially when you have dock doors opening and closing all day that allow trucks to dock and load/unload.
And less than 5% of the warehouses I've dealt with weren't insulated. Some were insulated poorly, but it's been so long since I saw one that truly wasn't insulated I couldn't even tell you the name of the project. And I remember drawing a big X across that warehouse on my proposal and writing "not in contract." I lost that bid because of that exception, and it was fine with me.
(Worker comfort aside, there are also a lot of warehouses which require a tight tolerance on temperature and humidity, or else their product will spoil. Pharma storage comes to mind right off the bat, there are many others)
