Cooler Home during 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 but far from what needs to be known.
The uninformed, are those who insist that whatever they think, or have, is the best.
The well informed, seek out the knowledge and implement it, despite their seemingly isolated social choice.

That having been said......

Often it is presumed that just ventilating the roof is going to be sufficient whereas the reality it is only half the story, which provides less than half the potential of keeping a home cooler naturally in the summer months.

Yes, venting the roof will reduce the overall heat retention of the building however the exercise is to be proactive and make living conditions comfortable in the rooms below without incurring the high and higher cost of using an air conditioner

Obviously those with 2.7m ceilings are going to have a cooler rooms longer than those with 2.4m ceilings and 3m ceilings cooler again

Those with raked or cathedral ceilings will have a situation proportional to the height of the roof and the resistance (insulation) contained within.

To begin with the homeowner needs to feel confident that the concept of ventilation is a worthwhile and is a cost efficient exercise.

To explain this simply consider the following,

Fill a bucket with water and obviously if you put a hole in the bucket the water is going to escape. The bucket will empty proportional to the hole, the bigger the hole the faster the escape.

This is the physical 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 and down comes the balloon.

Ventilating a roof, is precisely that, allowing the heat to escape so it doesn't build up in the form of back pressure and transfer into the rooms below via conduction

On the roof, the hole is what is essential....the size of the hole dictates the efficiency, and one large hole is more efficient than many smaller

The device on top of the hole is called a roof ventilator......and all roof ventilators are not equal

To gain the optimum performance out of roof ventilation....read roof ventilation refinements.
