Would you care to expand ? I know that there are architectural trick to improve the heat management, for example i plan to plant a tree which will grow big enough to make shade on my window during summer.

But personally, I did not see yet an old building in Europe which is both warm in winter and cold in summer jusy by itself. The new insulation materials are really good now, there is no comparison with old techniques. My parents house is 200 years old, made of a wooden frame and brick. It is incredibly cold in winter, so cold that we need to burn wood as central heating is not powerful enough.
