The dissertation work is devoted to the development of the typology design of Passive House dwellings on the territory of Ukraine. To achieve the purpose, the fundamental principles influencing the spatial architecture layout design and structural solutions of passive buildings have been analyzed. In addition, the technical-engineering and typology requirements for Passive Houses dwellings relevance to various climatic zones of Ukraine have been determined. Demographic factors that influencing the typology of passive houses have been investigated, as well as the statistical data on the composition of the households has been analyzed. For the first time, the map of the demographic composition of the households in the architectural-climatic zones of Ukraine has been compiled. The percentage of living rooms in social houses in these areas has been revealed. As a response to this issue, an analysis is performed for an indicator of the compactness ratio of the building shape concerning various Ukraine’s households taking into account the room count. Nevertheless, the method whereby linear terraced dwelling houses is proposed based on detailed simulation analyze, to improve the compactness ratio of the Passive House dwellings. Calculation of the recommended thermal resistances (R-values) for the building envelope components in terms of their compliance with the optimal recommended value by Ecofys in the EU for houses with a traditional heating and ventilation system is conducted and proposed. The fundamental principles of spatial architecture layout design solutions for dwelling houses in Ukraine have been systematized and outlined. This is achieved by taking into consideration the premises orientation, availability of buffer zones and sun rooms, characteristic principles of spatial architecture layout design, options of terraced houses, the features of the building envelope include window-to-wall ratios, room parameters, the optimal location of solar collectors, etc. Typology requirement of the structural solution for Passive House dwellings is developed with the purpose to improve the energy efficiency of buildings. As a response, translucent structures component with the use of sun-protection devices is recommended for protection against overheating during the summer period. A patent invention of these elements is implemented. The components of the ventilated roof, options of the building envelope thermal insulation, application to high-efficiency windows and the rational orientation of the openings in the building envelop and the like are proposed. In order to improve the ecological aspects of buildings on the territory of Ukraine, it has been developed and proposed structural solutions of the walls, constructed with locally available and generally sustainable materials with application to modern highly thermal heat insulations. The questions of technical-engineering solution for Passive House dwelling standard, which fundamentally consists of an energy limit: net useful energy demand for heating and cooling of 15 kWh/m2/year and total primary energy consumption of 120 kWh/m2/year. These requirements are taken into account to determine the issues relating to the tilt angle and integration of rooftop photovoltaic and solar panel, whereby using a subsoil heat exchanger with various shallow geothermal methods to keep the heat exchanger of the ventilation system frost-free. Compact heat pump units, combining heat recovery ventilation with heating, hot water supply, and storage in one unit for this purpose, while utilizing the solar power for air conditioning refers to using the sun's power or energy to cool the house. The method of determining the optimal tilt angle of solar collectors for different regions of Ukraine is proposed taking into consideration the annual cloudy condition. The calculations are made for several cities located in different climatic zones. The dissertation achievements have been incorporated into public documents, including national regulatory documents on issues related to the design and reconstruction of passive buildings, as well as methodological guidelines focuses on preparation specialists within existing disciplines of architecture and construction. The contributions of the dissertation have also been implemented in design and construction practices.
