Help Me Design/ Build a Shop

[dieselscout80]

I found that having a company install a 30X60 12 ft eave carport style building with 3 10X10 roll up doors and a man door on a concrete slab was the best option for me, I had a concrete contractor install a 4 - 5" thick slab (5" under the planned 2 post lift) for 12k and the building installed (shell with exterior doors) was 20k. down here pole barn with the posts in the ground is a no go for me.

DaBear3428, I'd like to see some more details on your vent fan you installed in your carport style building. Also, how well does it work at cooling your building?

I put this one in mine. I did the calculations based on advertised CFM and going off memory it should replace the air in my shop about every 7 min or so. I wouldn't say it cools the shop but it does a good job of pulling the heat out. It seems to feel cooler with the big door closed and windows opened while it's running. Like there is too much open area with the big door also opened. It's also a lot quieter than I expected. You can hear it running but it doesn't effect conversations.

works well but draws in a lot of dust.
i'm building out a conditioned office/machine room 20X30 to keep my mill,lathe and other sensitive equipment from getting dusty and rusty.

same one i put in, if i leave the doors open and stand in the door it helps alot but you are right you still have the steel covering the building getting hot and radiating infrared onto you, so i would say it keeps the building from being an oven but in 100deg summer heat in direct sunlight on the building there is only so much a fan is going to do. there is about a 15deg diff in the shop with the fan running but it is still 100deg so. i cannot stay in it without the fan running right now.

The double bubble insulation I put in my building made a BIG difference in the radiant heat. With a little air flow my building is no hotter inside than outside and being in the shade it feels cooler in the building than outside.

what is the CFM valve you use for that?

My one shop-30x40 is uninsulated and only has one door and no windows. After noonish it almost too hot in there

Mine shows 5088 CFM. You would need to calculate the cubic feet of your shop to be able to get to the minutes for complete change out. But I would say get the biggest one you can afford that will fit in the space. I don't think you can have too much. I wish I had a dozen of them.

Thanks for that info.

The garage and horse stable both have a 3ft x 3ft coupola. I installed this fan in them, 2 speed. 9,600 cfm. They're nice and pull lots of air. I had to bend the coupola louvers up a little because of the cfm but they work great.
I know there are pros and cons to trees but I have healthy large oaks & maples around both and shade really makes it nice.

Our farrier & his wife were out yesterday and fan running and end doors open a little it was really comfortable. Doors open a little increases air velocity.
