Authors	Yu. Tabunshchikov, M. Brodach, Moscow Institute of Architecture (State Academy), Moscow, Russia
Abstract	In accordance with the principles of the system approach mathematical model of the thermal behavior of the building as a single energy system should be presented in the form of three interrelated models, more convenient for the study: - Mathematical model of heat and power impact of the outside climate on the building; - Mathematical model of the heat accumulative characteristics of the building envelope; - Mathematical model of heat and power balance of the building premises. An optimization problem for the energy efficiency of buildings has the following contents: identify indicators of architectural and building engineering solutions that minimize energy consumption to create a microclimate in the premises. The article presents the solution of the optimization problem, including the implementation of mathematical models as a single energy system. The article shows that, for example, the solution of the problem of optimal control the flow of energy during heating up period after temperature set back, provides a 70% energy saving
