Smarter Energy Solutions for Every Building

Our patented Thermal Energy Storage Foundation (TESF) and patented Smart Controls make any structure—homes, offices, or commercial spaces—more efficient, affordable, and sustainable.

Our patented Thermal Energy Storage Foundation (TESF) and patented Smart Controls make any structure—homes, offices, or commercial spaces—more efficient, affordable, and sustainable.

Thermal Energy Storage Foundation (TESF): A New Standard in Sustainable Living

  • Redefining the future of sustainable living, our patented Thermal Energy Storage Foundation (TESF) creates the most energy-efficient, affordable, and environmentally responsible home in the United States."

Our patented Smart Controls work with any building—homes, offices, or commercial spaces—providing intelligent energy management and maximizing efficiency.

Any type of foundation can be redesigned to become a thermal storage foundation, making TESF adaptable for new construction or retrofits

  • Collaboration with North Dakota State University (NDSU) for performance studies.

  • Pending USDA and NSF grants for further research

Key benefits:

  • Up to 50% Federal Tax Credit: Covers the entire foundation and heating/cooling systems.

  • Cost Efficiency: LCOS of just 1.5 cents per kWh—exceeding DOE 2030 goals.

  • Grid Support: Reduces peak electrical loads and costs.

“The system works like a ground source heat pump but uses pipes in controlled low‑strength material under the slab instead of buried loops. Because the material properties are well known, no thermal response testing is needed, and performance can be accurately predicted with tools like COMSOL or EnergyPlus”.    Yao Yu Ph.D
