The dissertation is concerned with the energy supply for a low-energy single family house and its influence over the energy performance of the building. The main goal of the study is to compile an integrated assessment model for an energy supply system for a low-energy single family house. The compiled model may be used to comprehensively analyse the energy demand for a building and the energy supply systems as well as to determine a rational solution in terms of selected assessment criteria, i.e. energy efficiency, environmental impact, economy, comfort and functionality.

The dissertation consists of an introduction, three chapters, general conclusions, a reference list, a list of publications on the topic of the dissertation by the author, and three annexes.

The research topic, the relevance of the study, the subject of the research are discussed as well as the goal and tasks of the work are formed, the research methodology, the scientific novelty of the work, the practical significance of the results and the defended statements are described in the introduction. At the end of the introduction the publications and presentations at conferences by the author are named and the structure of the work is presented.

The first chapter of the work presents an overview of the relevant literature; it is concerned with conceptions of high-efficiency buildings, evaluation and certification systems of these buildings, indicators of energy efficiency and applied passive and active energy efficiency measures. Modelling and optimisation methods applied to the evaluation of buildings and their energy supply systems are also overviewed.

The second chapter provides a compiled model of integrated assessment of low-energy building energy supply system and its application algorithm.

The third chapter presents an assessment of various variants of energy demand for a low-energy single family building and 15 energy supply systems that ensure this demand, while applying the compiled model. The final result – a rational system of energy supply in the case of an efficient building energy demand based on the criteria of energy, environmental impact, economy, comfort and functionality – is presented.

9 scientific articles have been published on the topic of the dissertation: one in a science journal that has been included in the ISI Web of Science, two in other science journals, five in the reviewed materials of international conferences, one in the material of a national conference.
