New House, Many solar questions

[jerrye]

Ladies & Gentelmen,
I'm currently looking for an Architect in Queretaro Mexico to help design & build my new house in Colon Mexico.
With the high cost of electricity most homes do not have heat & cooling.
The location where I will build the house has a small pond 100 ft x 300 ft with water that is approx 68 degrees year round, I plan to use this water with in floor PEX piping or water to air exchangers to cool the house and build solar collectors to heat the water for heating. As this house is located out in the country and will be constructed with local labor that I will manage. The use of high tech materials and equipment that are not available in this area of Mexico will prohibit many of the standard solar installations you see in the States.
Any ideas that you have would be greatly appreciated
Other ideas that I will incorporate are
> 3 ft eve overhangs
> White roofing material
> Compact Fluorescent lighting
