Every house in Eno Commons incorporates a geothermal heat pump and other green technologies.
Fromhttp://www.ncgreenbuilding.org/site/ncg/public/show_project.cfm?project_id=174, "Advanced Energy did a follow up energy use study which proved that homes at Eno Commons on average used 60% less energy for heating and cooling than the average for homes built in the same time period (using Duke Energy's North Carolina database for 1998-1999)."
I seem to recall the upfront additional expense of a geothermal heat pumps was in the neighborhood of $5K (includes a $2K discount from economies of scale). So the payback period is about 5 years.

We are a newly forming co-housing group in Ulster County New York, and weare currently in the design stage. We are discussing the costs of "building green", installing solar, geo thermal, etc... We are wondering if anyone has any information about balancing out the initial costs of building green, versushow long it might take to get back the initial extra investmant in energysavings. We know, of course, the value of building green, but need some feed backon the financial part. Thanks, Lynne James, Ulster County Co-Housing _________________________________________________________________ Cohousing-L mailing list -- Unsubscribe, archives and other info at: http://www.cohousing.org/cohousing-L/
