Excellent sources, thank you.  It occurs to me that I might want to build an 
upper deck over the South windows, where the river view is.  I can use this 
software to make the deck act as a sun shade in the summer without blocking the 
view - and have an upper deck to sit on as well.  

Thanks!

Lloyd,
look at http://www.squ1.com/products/ecotect/features/shadingdesign 
or http://www.squ1.com/products/solartool 
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!
