zero energy home (ZEH)
A home that combines state-of-the-art, energy-efficient construction and
appliances with commercially available renewable energy systems, such as
solar water heating and solar electricity. The combination results in a
home that produces its own energy – as much or more than it needs.
Even though the home might be connected to a utility grid, it has net zero
energy consumption from the utility provider.

These homes have a number of advantages:
The U.S. Department of Energy has partnered with building professionals
and organizations to further develop the Zero Energy Homes concept. To date,
only a few prototype Zero Energy Homes have been constructed and researched.
- Improved comfort – an energy-efficient building envelope reduces
- Reliability – a Zero Energy Home can be designed to continue
functioning even during blackouts
- Energy security – a home that produces energy protects its owner
from fluctuations in energy prices
- Environmental sustainability – a Zero Energy Home saves energy
and reduces pollution
