The Issue

We, the undersigned residents of Whisper Valley, call on The Whisper Valley Master Community, Inc., Taurus Investment Holdings and EcoSmart Solution, LLC to take immediate action to address dangerously high geothermal water loop temperatures in our community.

For months, Entering Water Temperatures (EWT) have been consistently above 90°F, which is far beyond safe or optimal performance levels for geothermal systems.

Elevated EWTs:

Reduce cooling efficiency and increase energy use.
Drive up utility bills for every household.
Cause accelerated wear and early failure of HVAC units—leading to costly, preventable repairs.
This issue directly undermines Whisper Valley’s advertised promise as a “zero-energy capable” community. With EWTs at current levels, that standard cannot be achieved in practice.

It also risks violating the spirit of affordable housing commitments within Whisper Valley. Homes built through Austin Habitat for Humanity and supported by Austin Housing Finance Corporation (AHFC) funding are required to remain affordable in total cost of ownership—including utilities and maintenance. If the geothermal system inflates those costs, it undermines both affordability and sustainability goals funded by public resources.

Our Demands
We urge Taurus Investment Holdings to:

Acknowledge the current EWT readings and their negative impacts on efficiency, affordability, and equipment longevity.
Provide a detailed remediation plan to lower and maintain EWT within industry-recommended ranges.
Commit to transparent, monthly reporting of loop temperatures available to all residents.
Clarify how the “zero-energy capable” standard will be achieved—or amend marketing to reflect reality.

Why This Matters
If unaddressed, this problem will harm every Whisper Valley homeowner—raising bills, reducing comfort, shortening equipment life, and compromising the community’s reputation as a leader in sustainable living. It also jeopardizes the affordability commitments made to the City of Austin and to low-income families who trusted the community’s promises.

Sign this petition to demand Taurus Investment Holdings honor their commitments, protect our homes, and ensure Whisper Valley remains both green and truly affordable.
