How to get the fresh outdoor air into the besement garage?

The basement has concrete wall. To get fresh air, how to design
the fresh air duct to basement?  

Thank you all for previous answer!

RE: How to get the fresh outdoor air into the besement garage?

Find a basement wall that backs onto a suitable yard (owned by the client)

from outside, dig a hole and form a concrete 'box'.

At ground level raise the 'box' by 150mm to form a ledge or 'upstand'

At basement level 'break in' to the basement to form a 'communication pathway'.

At outside ground level build a weathering skirt that goes over the 150mm high upstand.

The skirt should comprise of a duct with a louvre in it to let in (or exhaust) air.

At basement level you may use the new connection as natural ventilation or add a fan for mechanical ventilation.

voila

(I've done this quite a few times with no problems.)

good luck and use a good builder...make sure the new concrete box is suitably weatherproffed and waterproofed

Also make sure that the basement has a good footing drain system in place, and that your installation doesn't disrupt same.
