So when you buy a west or worse east facing condo with those big glass walls that are fashionable now in Bangkok (Wow! Look at that view!) you don't think of the expense and years of misery you are taking on. But let's start with my glass door to a small veranda exposed this month to morning sun from about 8 to 11 am. Here are the calcs for refrigeration capacity and expense. A sunny morning heats the curtains to about 50 C, which then serve the same function as hot water radiators. To offset this added heat I need a dedicated 26000 BTU split air conditioner unit, it barely provides the needed 10 kw of cooling power (2.6 kw electric power). So maybe you need two such units for this small room?
But you have plenty of money, so problem solved!
No, not at all. When you look at that curtain on waking up, you are looking not at a 25 degree cooled wall, but at a 50C heating panel, and though the room air may be 25 C, you are feeling that blast of radiant heat, as unwelcome on your face and body as it might be welcome in a northern ski lodge.
I will claim that it is not possible to live comfortably in such an environment, being driven from bed every morning because of solar heating via windows, regardless of air conditioning and curtains, blinds, etc which do little to prevent heating in the room, especially radiant heating from interior window coverings (or tinted windows). But anyone who has ever parked a closed car in the sun knows this already!
