In modern conditions the building can not only consume energy from the outside, but also produce its own. A new role has acquired such energy sources as the sun and wind. Energy saving in architecture follows from the requirements of regulatory documents and includes: the use of alternative energy sources, the installation of energy-saving equipment. Using examples of modern technologies, it is shown that along with energy savings, it is possible to create environmentally friendly and more interesting architectural images. The basics of the formation in the architecture of energy-efficient spaces, methods and techniques of using the energy of the future in the architecture of Kazakhstan are studied.
