A building is designed, constructed, and maintained in a nature-friendly manner by applying energy load reduction, high-efficiency energy facilities, resource recycling, and environmental pollution reduction technologies. This place is designed to minimize environmental damage until the end of the building's life. Technology that reduces the energy load required for buildings is the most basic technology element for green buildings, and it is essential to improve the efficiency of facilities to reduce energy consumption. In addition, environmental pollution reduction technology should be supported to reduce the occurrence of various pollutants from buildings and reduce damage to the surrounding environment, and technology can be applied to reuse waste resources from buildings or to minimize environmental damage.

A zero-energy building is a building that has a net zero energy consumption. According to the 'Renewable energy technologies for sustainable development of energy efficient building' engineering journal, the total amount of energy a building consumes annually is equal to the amount of renewable energy generated on-site, or renewable energy sources, off-site. It uses technologies such as heat pumps, high-efficiency windows and insulation, and solar panels. The goal is to reduce the greenhouse gases these buildings emit into the atmosphere during operation. It may consume non-renewable energy and produce greenhouse gases, but it may also reduce energy use and greenhouse gas production elsewhere by the same amount. The development of zero-energy buildings is driven by the desire to reduce environmental impact, as well as tax and energy cost reductions that make zero-energy buildings economically viable.
