Developing an EnergyPlus-Based Simulation Model for Energy and Comfort Analysis of an Office Building in Debrecen

Abstract:

Buildings represent nearly 40% of global energy consumption; therefore, improving their energy efficiency and thermal comfort has become a key research priority. This study presents the development of a detailed EnergyPlus-based simulation model of a five-building office complex located in Debrecen. The model integrates geometric, building physics and HVAC system characteristics, real operational schedules, weather data, and occupancy profiles. Simulations evaluate electricity and heat consumption as well as thermal comfort indicators such as temperature and PMV. Results show that the model accurately reproduces annual heating and cooling energy demand: simulated heating demand (2190 GJ) closely matches measured data (2108 GJ), while simulated cooling demand (119,283 kWh) aligns with measurements (119,356 kWh). The model provides a reliable foundation for future optimization studies, including data-driven and hybrid predictive control strategies. Future work includes calibration using real measurements and the integration of AI-assisted control.
