Cooler Home in Summer Months
In all societies there are the gullible, the uninformed and the well informed.
The gullible, listen to whom ever has a little knowledge.
The uninformed, are those who insist that their beliefs cannot be wrong.
The well informed, seek out the knowledge and implement it.
Often it is presumed that just ventilating the roof is going to be sufficient whereas the reality it is only half the story, which in turn is half the potential of keeping a home cooler naturally in the summer months.
Venting the roof will make living conditions in the rooms below without an air conditioner.
Rooms with ceilings of 3 metres in height are going to be cooler longer than those at 2.7m ceilings and 2.4m ceilings being less again.
Rooms in houses with raked or cathedral ceilings will be warmer than those having an attic void above them.
The homeowner needs to feel confident that roof ventilation is a worthwhile and a cost efficient exercise.
To help explain this, consider doing the following,
Fill a bucket with water and obviously if you put a hole in the bucket the water is going to escape as the hole allows, the bigger the hole the faster the escape.
This is the principle governing the escape of water in a contained area and the physical principles governing heat in a room is the inverse or opposite to, water in a bucket.
Imagine the bucket upside down like a hot air balloon and pour heat into it, the warmest air is going to be at the top of the air balloon, which is the energy that causes a hot air balloon to rise
If you put a hole in the top of the air balloon the heat is going to escape bringing the balloon down.
Ventilating a roof is allowing the heat to escape so it doesn’t affect the temperature of the rooms below
A hole in the roof is essential ….and the device over the hole is called a roof ventilator
It’s efficiency is based on it’s design and all roof ventilators are not equal in performance.
