The temperature and humidity in Malaysia means that air-conditioning is practically a must in any home. In heavily urbanised areas, the air is completely still on most days, even if you opened all your windows and doors. What else can you do but reach for the remote control?<\/p>\n

The problem is, even with proper maintenance and care and regular air-con servicing<\/a>, air-conditioning is an enormous energy guzzler, taking up 30% of a typical household electricity bill<\/a>.<\/p>\n

Is it possible to design a home that stays cool naturally, thus reducing the dependency on air-conditioning?<\/p>\n

Here are some upgrades you can make that will allow your homes to stay cool without air-conditioning.<\/p>\n

1. Increase the overhang of\u00a0your roof<\/h1>\n

Depending on which way your windows are facing, you can extend the overhang of your roof so that only direct morning or late evening sun comes straight in. This is particularly useful for bedroom windows.<\/p>\n

3. Use high spaces as a solar chimney<\/h1>\n

Warm air naturally rises. If you have a stairwell, find a way to ventilate it so that the warm air can flow out the top, and cool air can enter your home through vents lower to the ground. This can be achieved by adding vents along the top part of the wall, or even a skylight vent.<\/p>\n

4. Install a roof turbine<\/h1>\n

A roof turbine is a turning device about 20cm in diameter. As the fins catch a light breeze, it turns and creates an area of negative pressure below it. This negative pressure sucks the warm air from inside the house and sends it outside, allowing cooler air to enter the house through the windows and under the doors.<\/p>\n

In one study, these rooftop turbines were found to reduce the attic temperature by up to 6.4 degrees Celsius<\/a>.<\/p>\n

5. Open up doors and windows for maximum cross ventilation<\/h1>\n

Your house should allow as much wind to flow through it as possible. That means large windows (or full size sliding glass doors), less wall partitions, curtains, or tall bookshelves. In general:<\/p>\n
