Optimization of energy efficiency of a multi-profile medical center building

Abstract

Purpose. Increasing the thermal efficiency of a multidisciplinary medical center building by optimizing architectural and planning solutions, taking into account climatic conditions and improving the parameters of engineering systems. The building is considered as a single energy system, the efficiency of which is determined by the interaction of external and internal factors. Methodology. Is based on mathematical modeling of heat and mass transfer, analysis of climatic data, and calculation of energy consumption in accordance with current standards. The study takes into account the effects of solar insolation, wind loads, outdoor air temperature, air infiltration, and thermal insulation of building envelopes. An indicator of the efficiency of a design solution is proposed, which assesses its deviation from the energy-optimal variant. Findings. Are based on the example of a multidisciplinary medical center located in the city of Dnipro. An analysis of insolation according to the orientation of facades was carried out, thermal gains through transparent and opaque elements were calculated, and heating and cooling loads were determined. Seasonal climate variability, thermal inertia of materials, and the operational regime were taken into account. The study confirmed that the building’s orientation, glazing area, ventilation system efficiency, and the quality of engineering equipment significantly affect energy consumption. A method for determining the optimal building dimensions is proposed, based on local climatic data and the potential of solar energy. Originality. lies in the substantiation of a systemic approach to energy-efficient design, which combines climatic factors, architectural constraints, and thermal characteristics into a unified model. A coefficient is proposed to evaluate the design solution in terms of its energy efficiency. Practical value. lies in the development of recommendations for reducing energy consumption. The proposed solutions make it possible to reduce thermal loads on engineering systems by 20–25%, lower operating costs, and improve comfort. The examined facility includes a ventilation system with heat recovery (up to 85%) and a heat pump with a COP of 3.5, which resulted in significant energy savings. The results confirm the effectiveness of integrating architectural design with modern engineering equipment and climate adaptation. The methodology can be applied to a wide range of public and residential buildings. Conclusions. Comprehensive energy-efficient design requires the integration of architecture, energy systems, and climatology. The proposed approach enables the development of projects that not only comply with standards but also ensure minimal energy consumption under real operating conditions.
