Theory

Site selection features prominently in the permaculture design course. I'd already come across the idea of passive solar from earthships. This concept is discussed in many places available on the interwebs. What I gained from my research were a couple of principles:

South-facing
Or north facing if you are south of the equator. To mitigate heat gain in the middle of the day, don't have a bunch of east or west facing windows, because the sun will shine right in them. North-facing windows will leak heat in winter (but are good for painting).
Trees
Be near deciduous trees. They'll provide shade in summer, and then will let the sun shine on your house when the leaves fall. But don't forget shade will block solar energy, too.
Overhangs
Put awnings or some such on your south facing windows at such a placement that corresponds to your latitude. In summer, they will block direct sun. In winter the sun shines through the window because it's lower on the horizon.
Wind
You might want some protection from it if you plan to grow anything.
Habitat
Try not to do anything anything in the rainy season that will disturb fishies' water.
Soil
Try not to disturb too much of the site. You'll just have to landscape, it, and mitigate any erosion.
