I promised yesterday to speak more on opening your windows to cool you house for free. Here I go.
It seems a no brainer to open your windows to cool your house, and save money and energy since you won’t need your air conditioner, after all, its what people did for centuries until A/C was invented. The problem is, today, it won’t always work. In order for open windows to actually cool your house, you have to get that outside air, and breeze, blowing through your place. This is the problem. Once A/C was invented, developers went crazy with the freedom, and began building houses without cross-breezes in mind – I mean, who would ever open windows when they had conditioned air. Out went the “long-thin-house plan, and in came the “cluster plan.” Here is the problem.
As you can see, with a cluster plan, the air can’t actually flow through the entire house, and what air does flow through, gets diminished and lost. It is terribly inefficient, but incredibly common. The long thin house, on the other hand, is quite efficient.
I am lucky. My house was built with the plan above. If we open all the windows at once, it can become a wind-tunnel, and is not so comfortable, so we only open a few windows, and things stay nice and cool.
I like being cool, and saving energy by opening the windows isn’t bad either.
