|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
