Forgive me for pointing out the obvious:
The smaller the window the more likely the house will remain cool in the summer and warm in the winter. The size will limit the amount of heat entering and leaving the house. Windows that are too large equal a large utility bill. The height of a house will also determine how it will keep energy. A high roof in a hot environment will assist in making the hot air go up while keeping the cool air down. A low ceiling in a cold environment will help keep the heat in.
It’s very simple to adapt the architecture to the environment and there are multiple examples in countries all over the world – low tech and hundreds of years old – that should be studied a little better.
I would go as far as studying a way to adapt the wall to the weather, instead of the window. How about creating moving walls to change the size of the window to the needs of each season like a tile puzzle?

For the lowest-e windows look here alpeneg.com
Not such a sexy web site, but the windows are by far the best, effectively like quad-glazed windows with two heat mirror films between two outer glazed layers. I used them here: netzeroenergy.org and I did a lot of research before purchasing, and very pleased with them. They are about as effective as a 2×4 wall, but let the light in!

I think passive solar energy is a great way to use it, because is less expensive than the active type, like PV for example.

We used low-E windows with a U factor of 31 on our new house in NW Arkansas. Tremendous results so far. I’m cataloging on the strategies I used in the construction of my home on my website. After foam insulation and a high efficiency heat pump, windows were the next most important part of our building project.
