Just thinking about these tropical climates and the immense differences in temperatures and humidity between building and environment... it takes a toll on the structures. Not saying it isn't possible, but it requires very elaborate environmental control systems and architecture. I think it takes more than just a powerful condenser unit for our A/C needs. It means serious investment.
The Brando is a wonderful example of what can be done in terms of 'natural' A/C. Especially since the system these days is able to deliver impressive results.
Sad to hear about Laucala. Any knows who is doing interim?
