Many people, having learned about the advantages of clay, straw or hemp concrete houses, decide to build their own house in this technology. Of great importance are construction costs, which are slightly lower than those of a traditional home. Green houses do not need to be heated very much, and energy is not used for air conditioning. Many people collect rainwater, which they use to water their gardens. They install natural domestic sewage treatment plants and renewable energy sources in the form of solar panels or wind turbines.

Institutions (schools, universities, museums, libraries, courts, municipal offices, hotels, hospitals, clinics, science centers), as well as sports buildings (stadiums, tennis courts, swimming pools) are mostly made of concrete, steel is used for construction, and facades are covered with aluminum and glass. Manufacturing and transporting these materials consumes a lot of electricity, heat, gas, and water, and when buildings are ready, they use up a lot of energy again to heat the interior or cool it in hot weather (air conditioning). The entire construction industry is very energy-intensive, requires more and more fuels and building materials manufactured in factories. Our climate is changing, it is getting warmer. Natural materials save energy and water and do not pollute the environment.
