I was surprised when one friend of mine told me she had no AC installed in her apartment. My friend lives in the second floor of an old apartment. Her husband hung a bamboo curtain in the balcony to block the strong sunlight. I think the position (orientation or direction ?) of a building is very important when it comes to indoor temperature. If one side of the building faces west, the outer wall would absorb the heat of the sun in the afternoon and in turn release the heat and cause the indoor space being warm. Unfortunately, my bedroom is in such a space. I’m considering to sleep on our living room floor since it’s much cooler than my bedroom.

We have several north-west facing windows in our home. I like it in winter to let the sun in. But for us in Jan & Feb can be very hot at about 38-45 deg C. We have full block window blinds but it can still be very hot and the air-con will struggle to keep up. Before the sun hits the windows in the morning of a hot day, we hang aluminium reflective foil on the windows. The foil is very, VERY effective and only costs a few dollars. If you cannot find the proper aluminium insulation foil, you can use kitchen aluminium foil or the same foil they use for making sun shades for cars. It really works. We use magnetic tape to secure them so it is easy to remove and put back on.
