I got a bit steamed when I read yesterday’s ST article, MOE seeks ways to beat the heat in class. It is looking into ways of cooling schools in our hot and humid clime.
Singapore’s mrbrown was not impressed. I’m not either, but for different reasons.
The first might be an error in reporting. Or it might be that I don’t understand north-south orientations:
Given that most schools don’t have a think-outside-the-rectangular-box shape, a north-south orientation is like a lower case “l”. This would mean the building absorbs the most heat throughout the day. To reduce heat absorption, the building needs an east-west orientation on its long axis; the windows need a north-south orientation (i.e., be facing north and south).
Then there is the reason for the move in the first place:
My suggestions? Make use of our plentiful sunlight to partially or fully power fans and air-conditioners. This might be expensive initially but it can pay for itself in the long run.
The other two suggestions I hinted at aren’t going to happen any time soon. We are held captive by the private bus companies and many teachers don’t know any other way of teaching.
End of nit-picky rant.
