For the Zero Energy Building Residence Alliance (ZEBRA) homes, BarberMcMurry teamed with Schaad Companies, Tennessee Valley Authority, Oak Ridge National Laboratory, and the U.S. Department of Energy on a combination research project and education campaign to design four homes to test cutting-edge energy-saving technologies and design strategies.

The homes incorporate high-efficiency lighting and appliances, water-to-air and water-to-water heat pumps. Ground-source heat exchange systems are used to reduce heating and cooling loads. The design groups plumbing and mechanical systems along one central wall in each home, minimizing energy loss within the home. Additional energy is reclaimed through gray-water and exhaust air streams.

Each home uses a different envelope system strategy: a structural insulated panel system, advanced framing, dynamic insulation, and exterior insulation.
