Renewable Energy Roadmap for Hospitals: ML-Enabled Forecasting and Sizing of a Hybrid PV–Wind System in Türkiye

Abstract

Energy use for heating, cooling, and lighting in buildings continues to increase, driving fossil fuel consumption and carbon emissions. Hospitals face especially high demand. This study designs and evaluates a hospital-scale hybrid renewable system (solar PV plus wind) for Diyarbakır, Türkiye, and develops real data-driven performance models to reduce energy consumption. Pace regression, incorporating weather and building characteristics, is used to predict PV and wind generation. Three months of data (Aug–Oct 2022)—average temperature 26 °C, peak solar irradiance 1012 W/m², average wind speed 1.18 m/s—and total electricity use of 2895 MWh were analyzed. Models were validated using RMSE and MAPE. Results show strong fit (PV: R² = 0.9262, RMSE = 0.037; wind: R² = 0.986, RMSE = 0.021). Estimated errors were 14% for solar and 11% for wind. Scenario analysis indicates the hybrid system could supply approximately 7.14% of the hospital’s annual demand via PV and 0.02% via wind. Even in modest-wind regimes, machine-learning-guided design enhances forecasting and sizing, providing a practical roadmap for public buildings in diverse climates to optimize renewables, reduce grid dependence, and lower emissions while maintaining service reliability.
