House orientation

As the last post indicated the green house design principles are up there on my want to know about list at present. One of the primary principles if you are starting from scratch is orienting your living areas with a northerly aspect and apparently this is true north and not magnetic north.

What is true north? The north point in this instance is the geographic point of the North Pole, rather than magnetic north that moves over time and doesn't relate to the orientation of the sun, which is what you are aiming at capturing in these living areas.

A concern people may have about orienting these living areas to the north, particularly in the sub-tropical/tropical regions, is that in summer such orientation could make these areas quite hot. Well, there are a number of things that can help to reduce this heating affect but one of the first ones is to shade these areas. Plant trees outside the living areas, for example.

Well now I have to get a map out and start searching for the perfect block of land to build a lovely house with green design principles embedded in its design.
