The article provides an overview of the main methods for increasing the energy efficiency of buildings. The main causes of heat loss in the building are revealed. The ways of solving the problems of energy consumption of new objects are shown: installation of alternative energy sources, improvement of thermal insulation of enclosing structures, installation of high-efficiency ventilation with heat recovery, use of energy-saving windows. The legislative base and state programs stimulating energy-efficient construction in our country are considered. A study was made of modern methods of building buildings, allowing to reduce energy and resource costs

Keywords: energy efficient buildings, energy resources, heat insulation, heat loss, geothermal heating, solar collector, energy saving windows
