Condensation Problem

[EFFIGUY]

Any help would be great, I have a 75x100 steel building where 2000sqft is cold storage and no insulation, in fall it sweats, I priced out spray foam like I have in the shop area but to do a 75x30 area I was quoted 17000.00 so I was told to install a fan in the gable and louvered vent on one wall for air movement, I called an HVAC company here in Vermont and they quoted me 13,800.00 (almost fell off my chair). Does anyone have experience with this ?
will the fan setup work? is there a fan company that will work with me and tell me what size fan to use for the space needing complete air changes.
When the weather changes here at this time of year it rains inside as the cold air in the building condensates on the metal roof due to the sun heating up the outside steel. I can purchase a fan but don't want to cut a hole in my new building to find it won't work.
I attached photo's of my hobby shop, still under construction. The white room with large windows is a machine shop. The building is spray foamed and has radiant floor heat. All lights are LED. The spray booth is a full down draft and matching down draft paint mixing room.

Thanks

There other post on condensation issue with metal building but wood structures can do it too.

The floor sweating will not likely change much as your fighting nature and physics. It's like trying to get an ice tea glass to stop sweating. Cold floor meets very warm moist air ( like we are expience this week) and it condenses. My floor is wet and two days from now when the weather turns normal the floor will dry again. In a second shop I condition the air year round, run a dehumidifier in the summer and the floor does not sweat.......but it is not in contact with the summer warm moist air because the door stays closed and the air inside is not humid. The flooor is still relatively cold compared a living space.

Others will comment on the metal structure issues.........

The steel I used for my ceiling has a "drip stop" coating. Basically it is a thin fuzzy coating that holds the excess moisture. I have plenty of air flow to dry it out.

I believe there are similar coatings you can spray on.
