Development of digital tools for calculating the energy consumption of residential buildings: heating and domestic hot water

Objective. The aim of the study is to create software tools that ensure reliable and consistently reproducible determination of heat loads and annual thermal energy consumption, taking into account the combined influence of climatic, structural, and operational factors.

Method. The methodological basis of the study involves structuring the computational process into a sequence of functional blocks implementing algorithms for calculating heat loads and annual energy consumption. The input data include the architectural and construction characteristics of buildings, the number of occupants, as well as climatic and operational parameters. The proposed algorithms are implemented in software modules tested on examples of civil buildings.

Result. Two software modules have been developed for calculating the energy consumption of heating and domestic hot water systems. The novelty of the study lies in the development of a concept for specialized software implementing algorithms for calculating heat loads and annual energy consumption, as well as in the creation of an automated method for determining the parameters of heating and hot water supply systems using aggregated calculation indicators. Software testing confirmed the correctness of the algorithms and the applicability of the developed solutions in engineering practice.

Conclusion. The developed software implements the automation of energy consumption calculations for residential buildings and enables consideration of key climatic, construction, and operational parameters. The presented algorithms determine peak and average heat loads as well as the annual energy demand for heating and domestic hot water systems. The obtained results demonstrate the efficiency of the software for optimizing energy consumption calculations. Verification of the software modules demonstrated high accuracy and stability of the computational results. The conducted study confirms the importance of digital tools in enhancing energy efficiency and promoting sustainable development in residential construction.
