WHISPER VALLEY NET-ZERO CAPABLE COMMUNITY

One of the ten biggest developments of its kind in the US, this sustainable, master-planned community features 7,500 Net-Zero ready homes.

The community will help the city of Austin meet it's target to reduce CO2 emissions to zero. Whisper Valley will eventually include 7,500 net-zero ready single and multi-family homes and apartments, plus 2+ million square feet of retail and office space across 2,062 acres (900 hectares). All structures will be geothermal and solar equipped, capable of achieving the Net-Zero energy (or carbon neutral) standard adopted by the City of Austin’s Municipal Building Code for all new construction homes. Austin has established a 2050 target to reduce carbon emissions to zero.

Whisper Valley homeowners incur no upfront costs for the geothermal system, as the ground loop infrastructure is pre-installed throughout the community.

Phase 1 of the community includes 239 homes (200 single family on 50-60 ft lots, 39 townhomes). 

REHAU RAUGEO™ Geothermal Ground Loop Heat Exchange

The community comprises 239 RAUGEO® U-bend vertical ground loops inserted in a borehole (created by a well-drilling rig) in each lot and a Bosch geothermal water-to-air heat pump in each home.  All vertical loops in the Phase I development are connected with district piping into a single closed-loop network that continuously circulates water and exchanges energy with the earth. 

The network absorbs stored heat from the earth in heating season and rejects heat back into the earth in cooling season.  Due to significantly higher demand for cooling in Austin, TX, two 250-ton cooling towers are used to augment the ground loop for heat rejection.
