What is a net-zero building?
A net-zero building or zero-energy building (ZEB) is one that produces as much energy on-site as it uses. In theory such a building would not be connected to any outside utilities such as electric or natural gas. All energy needs for heating, cooling, and lighting would be generated from within. However, a net-zero building could be connected to the electrical grid and use power from the grid at peak energy times but return an equal amount during off-peak hours.

The U.S. Department of Energy (DOE) is sponsoring the Net-Zero Energy Commercial Building Initiative. The goal is to achieve marketable net-zero energy commercial buildings by 2025. Refer to their website to learn more about this exciting challenge.Office of Energy Efficiency and Renewable Energy
