Thru Wall Ventilation

[pgtr]

Planning a new home build with a side facing attached garage and a detached garage/shop. Since it will be difficult to build a shed we asked the builder's architect to include a small space in the attached garage for garden 'stuff' (I currently have a shed for exactly this) - which he did. The nice thing about my current shed is I put in soffit vents and a ridge vent and that's where I store things like my mower, tractor, gas, etc...

The house (and detached shop) will have spray foam in roof and BIBs insulation in wall. Builder asked if I'd like insulation in the attached garage (they would just do batting in the walls and blown in cellulose in the attic.

This raised a question: What about ventilation. We are in the hot Southwest. I sometimes see newer homes with cast concrete grate w/ wire mesh behind it done on houses with rock siding (what we're getting). I was thinking of having them put such a wall 'vent' into my storage closet in the attached GA. Then maybe putting a fan in the ceiling to **** hot air up and out thru the attic/soffits/ridge vent or whatever...

In the below pic I put a red spot on the shed/closet to show a possible location for a wall vent... could also put vents in the doors into the closet/shed. One downside is it would be a great entry vector for scorpions. But then garages always are.

The soffits for the house will be closed but I could get vented soffits for the portion around the garage overhang...

Thoughts?

Installed a Tjernlund AS2 in wall between garage bathroom and conditioned garage. Does great job of pushing cooled air into bathroom in summer. Might give you some ideas on how to extend wall as a transfer duct to your desired outlet grill location. Mine is on a switch. You may be able to do something with thermostat control, timer, etc.

I don’t see wall vents in new construction anymore in garages, not sure what the reason is. I hate that gas fumes when you turn your car on in the morning just linger unless you keep the door open.

If it was me on new construction, I would just install a bathroom fan venting through the roof, maybe set it on a timer for an hour a day.

In my new construction, it was code inside our house to have a vent fan running, just to out gas the air.

Tjernlund, (pron. CHern-Lund) have a wide array of ventilation products available. The above referenced Air Shares are excellent and I have used thousands of them on projects with good results, but at your stage of build you may want other options for the garage. Tjernlund are a family operation manuf in Minn. Fine people and excellent products.
