00:00When the sun begins to beat down, windows, shutters and interior blinds should all be

00:13shut.

00:14Select clear, bright colours that reflect light and heat.

00:18Open windows at night to allow air to circulate, and evacuate heat that's built up during

00:23the day.

00:25If your home has several floors, open the upper windows to release hot air.

00:29This is known as the chimney effect.

00:32Try suspending a damp sheet in front of a half-open window.

00:36A simple thermodynamic principle is behind the resulting drop in temperature.

00:40When a fluid evaporates, it generates cold.

00:44Wetting floors around or in the house in the early evening has the same effect.

00:49A fan can be made more efficient by placing a bottle containing frozen water in front

00:54of it.

00:55The air that circulates is cooler.

00:58However, there's no point in leaving a fan on if there's no one in the room.

01:01A fan doesn't chill air, it just ventilates it.

01:05Thanks to evapotranspiration, whereby surface water returns into the atmosphere as vapour,

01:11plants can reduce the temperature in a home.

01:14Finally, limiting use of the oven and turning off all non-essential electrical appliances

01:20also helps keep the temperature bearable in extremely hot weather.
