Zero-net-energy building

A building that provides all of its own energy on an annual basis from onsite renewable resources or offsite renewable energy purchases. In this way it is still connected to the grid, providing power when it has a surplus and drawing from the grid when it needs power, such as at night. This approach involves using solar energy for electricity, water heating, and space heating, and employing design measures like passive solar design, natural ventilation, and operable windows for cooling with electric power assist.
