As defined by the U.S. Department of Energy, “a zero net energy (ZNE) is a building with zero net energy consumption, meaning the total amount of energy used by the building on an annual basis is roughly equal to the amount of renewable energy created on the site.” The NZP-ETI takes it a step farther, as it will generate more energy than it consumes each year. This excess energy, generated by an onsite photovoltaic solar array, can be stored in the center’s battery storage system or discharged back into the electric grid system.
