The promotion of energy saving and the utilization of Renewable Energy Sources (RES) is a key priority for IERSD, aiming at the rational use of resources, strengthening energy security, and an effective energy transition.<\/p>\n<\/div><\/div>\n\n

The European Union is committed to achieving climate neutrality by 2050 and has set specific energy and climate targets for 2030: a reduction in greenhouse gas emissions by at least 55% compared to 1990 levels, an improvement in energy efficiency by at least 1.49% on an annual average basis, an increase in the contribution of Renewable Energy Sources (RES) to at least 42.5% of final energy consumption (with a proposal to reach 45%), and the promotion of electricity interconnections between neighboring states to 15%. Greece has set a target for 2030 to reduce greenhouse gas emissions by 55% compared to 1990 levels. <\/p>\n\n

The climate crisis demands the rapid phasing out of fossil fuels and immediate energy transition actions towards renewable sources. Nevertheless, the Greek energy system<\/strong> still largely relies on fossil and imported fuels, and the electrical system has limited interconnectivity with European networks. <\/p>\n\n

The building sector<\/strong> plays a key role in European energy policy as it is responsible for approximately 40% of the total final energy consumption in the EU and about one-third of carbon dioxide emissions. Consequently, the most significant energy savings are expected to come from the building sector and will contribute decisively to achieving the goal of decarbonizing the European economy by 2050. In Greece, harmonization with the European Energy Performance of Buildings Directive (EPBD) began with KENAK, which first came into force in 2010 and was revised in 2017 with stricter minimum requirements. Since 2020, new buildings are nearly zero-energy buildings (NZEB), with very low energy consumption primarily covered by renewable sources. The major challenge is the enormous existing building stock, as the majority of Greek buildings were constructed before 1980 and are characterized by low energy efficiency and problematic indoor environmental quality. At the same time, buildings and the built environment must adapt to withstand the phenomena and impacts of climate change. <\/p>\n\n
