Lloyd,
look at

for a good shading design.

Dear Lloyd
Sunlight and shadow can be harnessed to provide
warmth in winter and shade in summer. Solar
geometry, i.e. gnomonics, is the name of the
game. This is of course the basis of passive solar architectural design.
In the northern hemisphere a south-facing window
can be protected by a canopy which screens
high-angle sun in the summer and permits solar
penetration in the winter. The design of such a
canopy is an exercise in applied
gnomonics. North-facing rooms would have
smaller well-insulated windows. Rooms on the
north façade would be those occupied only
intermittently store-rooms, wash-rooms, etc.
or those which themselves generate heat, e.g.
kitchens. Bedrooms might face east to attract early morning sunlight.
.
I would urge you to consider this approach to
architectural design. It would slash your fuel
bills and point the way for others to follow in
reducing global warming. But it may not produce an octagonal building!
