Zero-emission buildings, as defined in the updated Energy Performance of Buildings Directive, are based on comprehensive measures: an efficient building envelope, self-sufficient energy supply, and smart operation of technical systems. Maximum efficiency is achieved by combining heating, cooling, and ventilation into a multifunctional, integrated system. The operation and energy efficiency of such buildings are verified by dynamic modeling. The theoretical part presents energy efficiency standards and the concept of compact systems for heating, cooling, ventilation, and domestic hot water preparation. An architectural design of a model building and a simulation of the thermal response have been developed. The master's thesis will present and model a comprehensive integrated technical system with three key components: a recuperator, a heat pump, and a hot water storage tank. The compact device is designed for heating, cooling, and ventilating modern nearly zero-energy buildings, with the option of hot water preparation. The goal is to maintain thermal comfort while reducing primary energy consumption. The model enables energy analysis of individual components, their impact on the overall energy balance, and optimization of operation. Various hourly modes will be tested. We will also consider self-sufficiency through photovoltaic modules and battery storage and perform an economic analysis of the system installation.
