Renewalling Public Real Estate Asset in Sustainable Perspective: Guidelines from International Best Practices

Contemporary models of urban transformation emphasize regeneration as a strategic response tomitigate and reverse the negative impacts of urbanization. The acknowledgment of evaluation methodologies and frameworks for sustainable development in a global setting highlights the necessity to analyze the urban sustainability until the building-scale of analysis. Although sustain-ability is more measurable at broader dimensions, it is challenging to apply the same evaluation methodology to more constrained geographical areas with more detail. This complex framework makes measurement particularly difficult for those interested in studying urban sustainability from different perspectives. This paper aims to identify key indicators used to assess the sustainability at various urban scales, focusing on key categories such as economic-financial, environmental and socio-cultural analyses. Using a dual approach, a bottom-up perspective - which derives indicators from a real tangible case (the redevelopment of a public housing neighborhood in Le Lignon)- is integrated by a top-down one, which identifies commonly used indicators in key sustainability categories through a review of the literature. A comparative analysis of the results obtained from both approaches allows a set of key sustainability indicators to be formulated.
