Staying cool in 43 C

It’s officially 43 C in Melbourne, and my air conditioner died yesterday, yet the inside of the house is a relatively comfortable 26 C :

My office is a fair bit warmer because it’s a small room, and the desktop computer puts out quite a lot of heat [AMD processor], but it’s still bearable.

Magic? No, fire resistant shutters.

I wrote about my fire resistant shutters back in this post. They’ve never been tested in a bushfire situation, but by god they keep ordinary heat out!

The following pics were all taken from inside the house to show the shutters at work:

In the loungeroom
Inside the front verandah
Through the kitchen windows
Old fashioned evaporative cooling, and more shutters.

Almost every door, verandah and window in my house has been fitted with these fire resistant shutters. They weren’t cheap, but every winter since then, they’ve kept the warmth in, saving me money in heating costs. And in summer they keep the heat out, with or without the air conditioner. πŸ™‚

Much as I love my shutters, however, I have to say that on their own they would not have been enough. Part of the reason they work as well as they do is that I insisted on having an insulating foam applied behind the door and window frames. The foam fills up all the gaps in construction conveniently hidden by the frames. A small thing, perhaps, but the foam has stopped those elusive draughts from leaching the heat from the house.

Apart from the shutters and the foam, two more things helped keep us from melting today. The first was the weather overnight. The temperature dropped to 14 C which allowed the cross ventilation in the house to cool everything down before the heat climbed again. If it had been hot overnight, we would have been in trouble.

The second thing is that orange towel shown in the last picture. And no, it’s not my washing. :p

That humble towel is wet, and it’s hanging in front of an oscillating fan. As the water in the towel evaporates, it cools the air. The fan then circulates that cooler air around the small family room and into the kitchen.

My jerry-rigged evaporative cooling is probably good enough for some light cooking but…bugger it, we’re having take away! Ahem. I deserve it.

If you’re an Aussie, I hope you stayed cool and safe today. If you’re from the northern climes, I hope you stayed warm and toasty.
