Abstract:
The building sector is a major contributor to energy consumption and greenhouse gas emissions in the EU, driving policies that promote energy efficiency and renewable energy integration. European legislation and Romania’s NECP 2021–2030 set clear targets for building renovation and increased use of green energy to support decarbonization. This study presents an energy efficiency assessment of an existing building (Building B of the Palace of Parliament, Romania), focusing on the integration of photovoltaic and solar thermal systems. The work includes system sizing, energy production analysis, techno-economic evaluation, and estimation of environmental benefits through CO₂ emission reductions. Based on PVGIS data, an annual global horizontal irradiation of approximately 1,370 kWh/m² was determined. A 2,000 kW PV system installed on 10,000 m² is projected to produce 2,460 MWh/year. The solar thermal system is sized to cover part of the building's domestic hot water and heating needs. CO₂ savings are estimated at 1,230 tonnes/year.
