I don't understand where the 1 billion entry figure comes from?
Edit: Oh, I guess you mean "potential entry pool of a billion people." I think that's rather exaggerating a point. To take it further we could argue that we could add the billion or so people of India as the government magically decide to open up free movement to other countries too.
Anyway, I think that that looking at land supply and imaginary immigration numbers is really sidestepping the much more immediate issue of oligopoly (which also existed well before 1997).
This makes little sense. You suggested letting the market work. I highlighted the market in Hong Kong is far from a free market.
You have suggested using science but only referenced one of the way heat energy is transferred. You have ignored convection and more importantly radiation. It is possible for the sides of building directly in the sun to reach temperatures of 65 Deg C. Which makes the temperature differential probably comparable to less hot countries.
Yes insulation costs money and as every developed country will testify to get general market adoption of more energy efficient 'things' it needs to be mandated usually in a gradually manner with ever evolving and regulations that drive innovation. Building codes in Hong Kong for energy efficiency of residential buildings do NOT exists. This is terrible governance.
For those who are interested I managed to find some nice looking ceramic tint on AliExpress. $350 for 2 m x 1.5 m with free shipping. It's 80% visual light transmission so hopefully it wont be too dark.
Will let you all know how it works out.

No.
There are plenty of shops selling them. Suggest you head to the upstairs shops in MongKok

Our electricity bill ended up being only $565 this month with AC running 24/7. This sort of makes sense if the compressor is only running half of the time. That said it still makes sense to replace the AC since it'll drop this to around $390. I'm interested to see how much further this drops with both an efficient AC and blinds.
