Abstract

Background. At present, the issue of increasing energy efficiency of buildings and simultaneously ensuring the proper quality of microclimate subject to environmental parameter changes is becoming topical. Objective. The purpose of the paper is energy efficiency analysis as an energy system in the application of dynamic energy modeling, taking into account the relationship of thermal comfort indicators, thermal protection and microclimate parameters of premises under periodic heating. Methods. Dynamic simulation models based on the EnergyPlus software were created to study the building’s energy performance. To estimate the level of thermal comfort, an energy model of human heat transfer with surrounding objects based on the equations of human body thermal balance is used. Results. The graphic dependences of changes in the parameters of thermal comfort and microclimate parameters subject to regulation and changes in environmental parameters for the heating period are obtained. The specific energy demand for heating for the various heat-inertia features of the safety screens and depths of the temperature lowering during non-working hours, as well as for various heat-inertia features of the external fencing oriented on the S and the N is determined. The values of thermal energy savings are set at lower temperatures during non-working hours. Conclusions. It is established that the decrease of temperature by 4 °C causes decrease of PMV ≤ -0.5 for the Northern orientation, worsening conditions of people’s stay and is not appropriate. It is determined that the introduction of periodic heating modes allows achieving thermal energy savings of 16–25%, depending on the orientation, notch depth and the thermophysical properties of the safety screen. The increase in the range of fluctuations of the load on the heating system for the Southern orientation is due to additional heat inputs from the sun to the room area. The increase is also explained by the fact that periods of periodic shutdown of heating are characteristic for the beginning and end of the heating season. For the Southern orientation, the duration of the heating period is less than an average of 20 days.
