Justification for the Development of an Algorithm for Creating a Computer Simulation Model for Assessing the Energy and Economic Efficiency of Engineering Systems of Residential Buildings

This article examines the development of an algorithm for creating a computer simulation model (digital twin) for a comprehensive assessment of the energy and economic efficiency of design solutions and utility systems in residential buildings. A manageable and reproducible tool is presented that enables virtual experiments, comparison of alternatives, and justification of optimal solutions during the design stage. The proposed algorithm systematizes the collection and integration of various data – from architectural drawings and thermal performance data to utility system parameters and economic indicators – into a single model. The resulting tool minimizes risks and reduces operating costs. The algorithm will enable housing and utility companies and other management organizations to conduct online monitoring, remotely manage, and control the condition of buildings.
