This all depends on how much work you want to do, how you are with basic electrical connections and how much you want to spend up front vs how much you'd rather spend in electricity. Not that I've looked into this in any way.....

If you just hook up a standard gable fan like this it will run well enough and probably cool your shed a fair amount. You can also include a thermister like this which will give it a high and low threshold for operation. These can get pretty noisy though and if you leave it running all the time you'll probably see it on your bill.

For a bit more up front you can go with a full solar gable fan. Some models also allow connection to your 120v system so you can run them at night or during low sun conditions. These are great for situations like yours (or like my detached garage) where there isn't electrical yet or where you don't necessarily want to pay to have a fan run 10+ hours a day.

Vehicles run on the same output as solar panels (for the sake of this discussion) so you could easily cobble something together for less than $100 that would push as much air as one of those larger gable fans but also charge your cordless batteries, run low voltage lights, etc. You can also DIY a solar kit. I can get into the product details if you want, but overall you'd need:

  • solar panel
  • charge controller
  • low voltage wiring
  • speed/temp controller
  • 12v DC fan like this one.

    If the fan is too noisy or moving too much air (in extreme cases, depressurization can be an issue) you can control fan speed with something like this and I'm sure there are 12v temp controllers as well.

Not pictured, some weather stripping foam under the plywood in hopes of damping some vibration. Also I forgot to take pictures of wiring into the outlet in the crawl space.

The fan is a CX1500 "Cool Attic Power Gable Ventilator Fan"

The tools/materials I ended up needing:

  • 1 10mm wrench
  • 1 11mm wrench (Used for mounting the brackets)
  • Drill
  • Jigsaw
  • Screws
  • Hammer
  • Nails
  • Sealant (since its not an automatically closing one I sprayed some sealant on the wood to protect it)
  • SOG Multi Tool
  • The fan itself
  • 24" square 3/8ths plywood (could have been a bit more in the vertical really)
  • Wire to tie into the home power supply.
  • Wire nuts.
  • Weather stipping, self adhesive.

    I prepared the plywood first using the fan to draw a guide for the jigsaw. Drilled out a starter hole and followed the line with the saw. Also learned that I am bad at following lines.

    I had the 2x4 cut into 2' sections at Lowe's to save me some effort.

    Up in the crawl space/attic I nailed the 2x4 sections up, nothing special there and sprayed some sealant I had around. I also filled in some gaps in the gable vent (not pictured) with some foam backer rod I had extra of.

    Next went up the plywood with the cutout, I attached that with screws using the drill, much easier than swinging a hammer around up there. In hindsight, I should have picked up some longer screws and done the 2x4s with that too.

    Brought up the fan, mounted the brackets and mounted it to the plywood with screws. Had to bend it back a bit and adjust because there isn't a terribly large amount of clearance between the blades and the mounting bolts. If you buy one of these take note of that.

    I screwed the thermostat box to the brace in the path of the fan, wired in one end of the electrical cable following the instructions in the box - very straight forward. The load on the fan is fairly low, you can get away with 14-2.

    With everything else done, I killed the power and opened up the outlet up in the crawl space just across from the air conditioner blower. Didn't take any pictures of that, but basically just tied it into the black, white and ground wires from the house and closed up the outlet box. I removed the outlet to do it because I've never used it, nor have service techs. They just run an extension cord from in the house.

    Brought up the power and the fan worked. All in all if I take out the stop for breakfast, probably took me 2 hours. Hopefully it helps bring down the temps up there and make my summer bills a bit better.


    Edit - that thing I'm wearing in the picture is a Frogg Togg Chilly Dana, bandana. Really did help keep me cooler and acted as a sweatband.

Curious to see how much if any air from the hot exhaust migrates into the intake. Pink ribbon test held at various distances between the two holes when grills are/aren't attached? It looks like there is room to enlarge the intake hole higher and if there isn't any air migration, to the right. 100 degree intake might indicate some commingling so maybe not the right. Most of your big gains in performance may have already been made.

Another exhaust vent style.

I did just that for a GPU rig, though it was fairly gerryrigged. My basic shopping list:

  • Suncast BMS1250 Shed Tool Vertical, 22 cu. ft.
  • Suncast Shelf for Suncast Shed Models BMS1250 and BMS2000
  • Duraflo 620808 Gable Vent, 8-Inch X 8-Inch times 2
  • Holmes Dual Blade Twin Window Fan, White

    Assemble the shed and install the shelf, cut two holes in the front doors at the shelf level for the gable vents and one big hole in the back at shelf level for the window fan, and install/wedge items in holes accordingly. Cutting the holes was a pain, I thought a Dremel would work well but it's slow and loud as hell so I ended up using a drywall saw that worked surprisingly well. I ran a cord for a power strip out the back under the fans.

    Mine sits at the back of a covered patio that's about 8-10 feet deep, so it's not directly exposed to rain or any significant elements. You might be able to make it work if you've got some overhang and you can put the back of the cabinet up close to a wall where water won't hit the fans too much. I also glued some dust filter material to the inside of the gable vents to help filter dust out, and I blow the setup out every now and then.

That's going to be rough. Will the HOA approve dryer vents on the front of the house? Similar to this here

I know you said NO vents, but it's a dryer vent... :)

Depends on if you're doing to have a dedicated 'smoke sucker' or if you just need ventilation. I'd use one of these for ventilation. If you're sucking smoke straight from the source then 530cfm would be plenty.
