While inspecting the wooden BH at Papar, Sabah I saw these pipes like ventilation holes
connecting the BH nesting room and the ground area.
They were in a row and about 4 of them.
I was wondering what is so special about them.
I am sure the BH designer must have some reasons why he install these holes.
From what I can think of it has some thing about the cooler air.
Usually cool air are denser as compared to hot air.
If you put the hole on the floor you will have a high chance of cooling your BH.
Those air that entered your BH through these hole on the floor will be much cooler as compare to those from the normal ventilation holes.
However I was not too pleased with the way the owner channelled the cool air into the room.
He used a tee joint and connect in a straight line pipe with only two outlets per line.
This method will cause a kind of more resistance to those air.
I would prefer a shorter pipe length for example two of the holes will have two outlets.
In this way you can double the outlet holes.
Just an idea but what if the area is too cold at night?
Well it is up to you to wisely chose the best for your BH.
Use a bit of your brain so that you can improve your BH nests population.
