Reduction of energy consumption is more environmentally and financially advantageous than increasing onsite production to reach a low-energy goal. The less a home consumes, the smaller renewable-energy system it requires to reach net zero. Energy efficiency should always be the primary design strategy of a low-energy house. [1]

Energy-plus-houses at Freiburg-Vauban in Germany Prototype in Germany The Solar Settlement with the Sun Ship in the background: two PlusEnergy projects in Freiburg. An energy-plus building (also called: plus energy building, plus-energy house, efficiency-plus house) produces more energy from renewable energy sources, over the course of a year, than it imports from external sources.
Sustainable architecture uses a conscious approach to energy and ecological conservation in the design of the built environment. [ 1 ] [ 2 ] The idea of sustainability , or ecological design , is to ensure that use of currently available resources does not end up having detrimental effects to a future society's well-being or making it ...
Onsite generation of renewable energy through solar power, wind power, hydro power, or biomass can significantly reduce the environmental impact of the building. Power generation is generally the most expensive feature to add to a building. Energy efficiency for green buildings can be evaluated from either numerical or non-numerical methods.
A Zero-Energy Building (ZEB), also known as a Net Zero-Energy (NZE) building, is a building with net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site [1] [2] or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows ...
A "purely passive" solar-heated house would have no mechanical furnace unit, relying instead on energy captured from sunshine, only supplemented by "incidental" heat energy given off by lights, computers, and other task-specific appliances (such as those for cooking, entertainment, etc.), showering, people and pets.
Energy efficiency is not an attachment or supplement to architectural design, but a design process that integrates with architectural design. [8] Although it is generally applied to new buildings, it has also been used for renovations. In 2008, estimates of the number of passive house buildings around the world ranged from 15,000 to 20,000 ...
