Zero-energy building (ZEB), also called net zero-energy building, any building or construction characterized by zero net energy consumption and nil carbon emissions calculated over a period of time. Zero-energy buildings (ZEBs) usually use less energy than traditional buildings likewise as generate their own energy on-site to use within the building; hence, many are independent from the national (electricity) grid. ZEBs have emerged in response to stringent environmental standards, both regulatory and voluntary, introduced to deal with increasingly significant environmental issues like temperature change, natural resources conservation, pollution, ecology, and population.
