Whisper Valley is a peek into what the future could look like.

The sweeping community in the Austin suburb of Manor is filled with modern homes, small manicured lawns, quiet streets and rooftops outfitted with solar panels. Hidden beneath it is a network of pipes and man-made reservoirs that heat and cool hundreds of households via geothermal technology — a source that currently provides less than 1% of the U.S. electrical demand.

When completed, Whisper Valley will consist of approximately 7,500 owner-occupied and rental homes and multi-family units ranging in price from $350,000 to $750,000; three schools; 2 million square feet of commercial space; and 700 acres of park and outdoor community spaces. Habitat for Humanity is set to build affordable housing, which will hook up to the geothermal network.

Zac Turov, business development manager for EcoSmart Solutions, which runs the community’s geothermal system, says savings on utility bills for residents here with geothermal-powered heat pumps that cool and heat buildings can run up to $2,000 a year — based on a third-party verified Home Energy Rating System.
