A zero-energy home—also called a zero net energy (ZNE) home, net-zero home, or zero-carbon home—is designed so the energy it consumes annually is roughly equal to the renewable energy it generates on-site. This balance dramatically reduces overall greenhouse gas emissions compared to conventional homes. While these homes may sometimes draw on non-renewable energy, they offset that usage through renewable generation, resulting in a sustainable, net-zero footprint.

​

At Austin Touchstone Builders, we specialize in building custom net-zero homes in Austin, TX with airtight ICF construction and thermally sealed envelopes that reduce energy use by as much as 80% in Net-Zero Ready Homes, and in many cases bring monthly utility costs down to nearly zero in full Net-Zero Homes. Every home is pre-wired for solar panels, ensuring homeowners can seamlessly add renewable energy at any time.

​

Compared to traditional homes, our net-zero and ICF homes are engineered for unmatched resilience. They are resistant to tornadoes, hurricanes, flooding, wildfires, and termites, while also delivering lower operational costs, reduced maintenance, and superior indoor comfort. Quiet, durable, and healthy, these homes set the new standard for high-performance living.

​

We are proud to be a partner with the U.S. Department of Energy, certifying our net-zero homes through the DOE’s Zero Energy Ready Home program. Each certified home includes a certificate of authenticity and a unique VIN# issued by the Department of Energy—providing documented proof of performance that enhances resale value and monetizes your investment in energy efficiency and health.

​

While net-zero construction typically adds only 5–10% to the cost of a traditional build, most homeowners find the modest increase in monthly mortgage payments is fully offset by the drop in energy bills. The net result is often the same total monthly expense—but with a home that is higher-performing, longer-lasting, quieter, healthier, and far more comfortable.

​

The value of energy efficiency is also reflected in the housing market. A recent Freddie Mac study, “Energy Efficiency: Value Added to Properties and Loan Performance,” found that rated energy-efficient homes sold for an average of 2.7% more than unrated homes, with the best-rated homes selling for 3–5% more. This data reinforces what we see every day: investing in a custom net-zero home in Austin is not just good for your lifestyle and the planet—it’s good for your long-term financial future.
