Living in a big posh condo is the same as owning a big flash car...Costs more to run.
Not only that but structures made of concrete are just huge heat sincs..CHB`s are like batteries that store heat which is released all day long and in the evening.
Trying to fight that heat wit A/C power is expensive... 15K expensive!
When Im in Manila,I need the A/C on a lot too.
Our native style home in the province though works in a completely different way...Its cool inside and little need for A/C.
