Energy balance analysis and heating system modeling for a residential building

Abstract

Objective. The study focuses on the analysis of heating demand in the building, as well as on the design and modeling of the heating system. The thermal efficiency of the building is assessed, key factors are identified: external temperature conditions and internal heat loads. The study is devoted to the comprehensive analysis of the energy balance and the design of the heating system for a residential building located in Vicenza, Italy, using the Building Energy Modeling (BEM) method in the IES-VE 2023 software package. Method. Heating demand is modeled and calculated taking into account dynamic conditions, and the heating system is designed for optimal operation and energy efficiency. Advanced tools are used to model the system operation, which allows for optimized energy consumption and cost efficiency. Result. An air source heat pump and radiant floor heating system is designed and analyzed, the parameters of which are optimized taking into account hydraulic characteristics and heat losses. The results provide valuable data for the efficient design of heating systems and energy management in building projects. Conclusion. BEM analysis using an ideal system for energy balance, including both sensible and latent heat fluxes, showed a stable relationship between gains and losses, illustrating the thermal efficiency of the building. The results serve as a basis for further development and implementation of energy-efficient technologies in the design of heating systems for residential buildings in similar climate zones.
