Your best savings tricks for new construction?
I am about a month away from breaking ground in south eastern Kentucky. The house is a passive solar design using Thermocore SIPS, geothermal heating/cooling, a high efficency wood stove and looking to use all energy star appliances. Energy efficiency was on our list, but not a top priority when we gave our wish list to the architect (who, it turned out, was a passive solar specialist).
Now I'm fascinated with the idea of being as enegy conservative as possible/reasonable. Any additional suggestions or tricks we should consider before we start?
I've wondered about some method of retreving heat from shower and bath drains in the winter. Also considering some point of use hot water heating to supplement our geothermal water heating. We will have propane for our gas stove, so could use for water heating.
