bump because it is a mess.

I like passive solar wherever possible for heating/cooling.

plant trees/big shrubs to keep you cool in summer (south of you)
when they drop leaves in winter, you get the southern light.


plant evergreen trees/shrubs northwest of you. A constant windbreak to moderate temperatures.

also, use heated tiles to keep heat and give off heat - this is not solar, just what people have done for many centuries in Europe.
