Summary
For all new buildings, it is obligatory that hot water demand is partly covered by solar thermal installations (min. percentage: 60% per annum). This requirement is waived where the hot water demand is covered by other energy supply systems based on RES (art. 6 par. 3 Law No. 4122 and ΚΕΝΑΚ art. 8 par. 3.1.3).
The requirement for all new buildings to be Nearly Zero Energy Buildings (NZEBs) from 2021 onwards was further emphasised by Law No. 5037/2023. This law establishes more stringent NZEB standards in accordance with the revised Energy Performance of Buildings Directive (EPBD) (Article 9, Law No. 4122/2013, updated by Law No. 5037/2023), which prioritise energy efficiency and a greater concentration on renewable energy sources.
Furthermore, Greece has implemented a Long-Term Renovation Strategy, as outlined in Article 2a of Law No. 4122/2013, with the aim of improving the energy efficacy of its building stock. This approach establishes intermediate objectives for 2030, 2040, and 2050, with a particular focus on the substantial energy savings and emissions reductions that will be achieved through extensive renovations. The updated framework under Law No. 5037/2023 provides a precise roadmap for the decarbonisation of the building sector through targeted renovation policies.
The mandatory incorporation of renewable energy sources (RES) into heating and cooling systems for all new buildings and major renovations is a significant development under Law No. 5106/2024. In particular, renewable energy sources (RES) must account for at least 30% of the energy requirements for heating and ventilation, including heat pumps and solar thermal systems. Additionally, energy management systems are now mandatory for buildings exceeding 500 m² in order to optimise and monitor energy consumption (Law No. 5106/2024).
Law No. 5106/2024 has further tightened the certification procedure for Energy Performance Certificates (EPCs) to ensure that the energy performance of buildings is accurately represented, thereby further promoting energy efficiency. The objective of this initiative is to motivate building proprietors to implement energy efficiency enhancements. Furthermore, property owners who implement energy-efficient renovations and achieve a minimum of 20% energy savings are eligible for financial incentives, such as tax deductions and subsidies (Law No. 5106/2024).
