Energy efficiency is one of the central pillars of sustainable development, particularly in
the residential sector, since buildings account for a high portion of total energy
consumption and greenhouse gases. In the case of Greece, energy efficiency improvement
became a national priority due to the European Union's climate commitments, rising
energy prices, and the long-term problem of energy poverty. This thesis critically analyses
the energy efficiency policies implemented in the residential sector of Greece, examining
effectiveness, barriers to implementation, and the improvement potential.
Through an examination of key policies, including building performance regulations,
subsidy programs, and energy certification systems, this study assesses the extent to
which these measures align with Greece’s energy and climate goals. Additionally, it
investigates their impact on reducing energy consumption, lowering carbon emissions,
and enhancing the accessibility and sustainability of energy-efficient home upgrades. The
research also explores institutional, economic, and behavioral barriers that hinder policy
implementation, such as financial constraints, complex regulatory frameworks, and
public awareness challenges. To provide a broader perspective, the thesis compares
Greece’s approach to successful energy efficiency strategies in other European countries,
offering insights for policy enhancements tailored to the Greek context.
The findings show that while significant improvement has been registered by Greece,
policy implementation and public participation have significant shortcomings. A more
responsive and holistic policy with the application of economic instruments and
regulatory mechanisms to accelerate energy efficiency gains is necessary to solve such
problems. The thesis concludes with a set of policy implications aimed at improving the
effectiveness of residential energy efficiency policies, addressing persistent energy
poverty, and supporting Greece’s transition toward a more sustainable and equitable built
environment.
