Out of box thinking to cool roof


With the temperatures the way they are at Chennai now (106F / 41 C)  I explored the options of using the cool roof solution.  But then all Chennai homes have rainwater harvesting and the cool roof solution eventually runs into groundwater – is that going to create another ecological problem?

Then on Saturday I read about how OOB thinking is akin to madness and well, I am mad.madrasi, so it is time to think out of the box.  Coincidentally I heard that a good friend is about to try out cool roof – but it is also expensive – for my flat terrace, it would cost about Rs. 15,000/- (> 1000 sq. ft).

So I floated the idea of just white wash the terrace with lime – normal, good for nothing, useless lime (or white cement).  And lime getting into ground water should be harmless – isn’t it?  After all it is used for water purification.

Any thoughts?
