HN brings it up in threads on cooling, window heat gain and house design as a convincing case for awnings.

It's almost certainly insolation (sol, not sul). UV/IR rejecting film on the windows might help, given mild enough winters that blocking it year round is fine. Check out [VIDEO] If you can find someone willing to do it, dumping the heat (pumped out as air conditioning) directly into the pool would be quite efficient relative to heating the pool separately. Have it dump to the ambient outdoor air only as overflow when the pool's thermostat is satisfied (upper 80s or whatever).

> Passive cooling measures (e.g., window shutters) should not be overlooked as they cost nothing to run. Technology Connections just did a video on awnings. I'm not quite as puppy eyed about them as TC, but they are pretty darn effective. [VIDEO]

Reminds me of a Technology Connections video describing how helpful awnings are in reducing temperatures inside your house [0]. Are there any modern-looking awnings that wouldn't look out of place in my neighborhood? [0] [VIDEO]
