Buyak N. Evaluation of building energy system efficiency in thermal comfort conditions

The dissertation is devoted to the development of methodical aspects, methods and models of taking into account the influence of parameters dependent on the building during the design, operation and modernization of a complex "heat source – human – building envelope", development of research on the choice of a source of heat in a complex with building envelope. The analysis of the regulatory framework for energy efficiency of buildings and microclimate has led to the need to take into account the model of a person in determining the needs for heating and designing buildings. The method of choosing a heat source in a complex with building envelope based on the integrated value function is developed, which allows taking into account the change in the cost of energy and money in time. Energy, exergy and exergo-economic indicators have been developed, which allow to estimate energy efficiency of the system “heat source – building envelope”. The analysis of models of human thermal comfort has caused the necessity of creating a computer model based on the exergy concept and allowing to estimate energy indicators of thermal comfort, namely PMV and PPD. On the basis of which developed a regression model for determining the comfortable temperature of air in the room, which will allow to provide the microclimate in the room in accordance with the exergy concept. A model was developed for the analysis of the energy efficiency indicators of the "heat source – human – building envelope" system and the building heating need was determined depending on the parameters of the building and the person
