Do you know what this little vent is for?
If you look at the outer wall of the house, there may be such a small ventilation opening.
It is an important facility related to the ventilation of the house, although it is a part that I usually do not care much.
Just looking at it from the outside...
This is the air supply.
This is the exhaust.
You can't decide.
The important thing is not just to look at the ventilation openings, but to look at the flow of ventilation throughout the house.
Where does the air in the room come from, where does it pass through, and where does it come from?
In addition,
・ Whether the ventilation opening is blocked
・ There is no dirt or clogging
・ There is no abnormality in the surroundings
I will also confirm.
When looking at a house, it's not just the noticeable cracks and stains that make sense, but also these small pieces of equipment.
Do you have such ventilation openings in your house?
Please do not approach high places and check from a safe place on the ground.
