Residential buildings in Greece account for about 79% of the exclusive-use building stock and consume about a quarter of the total final energy consumption, with space heating and domestic hot water being the main energy end-uses. About 58% of the dwellings were constructed before the 80 s and the adoption of the first thermal insulation regulation. This paper presents the results from the Hellenic pilot action within EPISCOPE. The overall approach and analysis are based on the national TABULA residential building typology for single- and multi-family houses in order to estimate heating energy performance and savings. The work exploits Census and statistical data for defining the Hellenic building stock and empirical adaptation factors to make more realistic estimates from normative calculations. The analysis is supported by a detailed data disaggregation in terms of the number of dwellings and floor areas, based on envelope thermal characteristics, heat production units, energy carriers, use of renewables etc. The calculation results are adapted for the building types and then projected to the building stock. Numerous scenarios for different modernization rates are assessed for identifying the most promising refurbishment strategies in space heating and DHW for reaching the 2020 and 2030 national CO 2 emission targets.

This paper aims at implementing appropriate methodological approaches for a preliminary assessment of fuel poverty in Greece and analyzing in quantitative terms the potential impact of fuel poverty on public health. As regards the assessment of fuel poverty in Greece, both subjective and objective approaches have been implemented, utilizing primary data from existing surveys undertaken by National Statistical Authority, while the health impacts attributed to fuel poverty were quantified through statistical analysis. The implementation of objective approaches showed that around 20–25% of Greek households were in fuel poverty in 2013, while with subjective measures this percentage reaches to 29.5%, twice as in 2010. Furthermore, the regression models developed showed that the increased levels of fuel poverty observed after 2010 have had significant negative impacts on public health. Specifically, 1–2.7% of deaths recorded annually in Greece as well as the 2.7–7.4% of cardiovascular diseases and the 3.1–8.5% of respiratory infections treated by the Greek hospitals are attributed to fuel poverty. Taking into consideration that more than 60% of Greek households do not have adequate insulation, the development of ambitious energy saving programs for residential buildings could build synergies between climate change mitigation and fuel poverty alleviation.

Abstract: The latest developments in the field of energy supply, along with the major issue of the environment protection, set new priorities and yardsticks concerning the energy policies implemented worldwide. The development and implementation of effective energy conservation policies has been a target of the European Union ever since the days when it was still called European Economic Community. In this framework, and despite the successes already monitored, the need for further energy conservation in the building sector is a both an aim and a tool. Emphasis is being placed on the residential building stock and the improvement of its energy performance. Greece has been one of the last countries to adopt the Directive on the Energy Performance of Buildings. A thorough research regarding the nature of the Greek residential building stock helps in highlighting the problems associated with this delay, but also the perspectives for catching up with the other EU member states and achieving the aims set for the coming years. This paper aims at providing detailed information on the residential urban building stock, as determined in a field study in typical big and smaller Greek cities. [Copyright &y& Elsevier]
