A feasibility evaluation tool for sustainable cities – A case study for Greece

Designing measures for the reduction of energy consumption in urban areas is a complex venture indeed. In terms of urban sustainability, such measures affect energy efficiency as well as environmental, economic and social aspects. Numerous publications dealt with such methodological approaches in the past, whilst the subject of sustainable urban areas and cities is constantly gaining interest. Furthermore, energy performance depends on building density, occupancy and consumer profile, climatic conditions, not least construction quality, factors linked, directly or not, to socioeconomic aspects. Greek cities are known for their density, their polymorphic structure and their complexity. Thus, planning energy conservation measures is a difficult task, demanding a precise methodological approach, which will embody most of these aspects to a great extent. This paper proposes a methodology on how to manage Greek cities in terms of their energy efficiency, emphasizing on the residential stock. - Highlights: ► Analyzing Greek urban built-up environment. ► State of the art of the energy performance of Greek urban housing stock. ► Designing sustainable retrofit scenarios for Greek cities. ► Methodology approach for the energy performance of Greek cities.
