    Abstract: This study aims to develop an integrated classification methodology for retrofitting that preserves both energy use and cultural value aspects in hot climates, especially, in North Africa, as a hot zone, which lacks retrofitting initiatives of built heritage. Despite the number of existing methods of classification for energy purposes, little attention has been paid to integrate the perceptions of cultural values in those methods. The proposed methodology classifies heritage building stocks based on building physical characteristics, as well as heritage significance levels, and then later integrates the outcomes into a matrix to propose sustainable retrofitting scenarios based on three dimensions, i.e. heritage value locations, types, and heritage significance level. For validation, the methodology was applied to the heritage residential building stock along with a microscale analysis on a building in Khedivial Cairo, Egypt. The findings include extracting twelve building classes, providing a reference building for each class, and a detailed catalogue of the extracted reference buildings that includes retrofitting scenarios for creating energy models. The originality of this work lies in integrating cultural values in a building classification methodology and providing a list of sustainable retrofitting scenarios for reference buildings. The findings contribute to fill the gap in existing building classifications, more specifically in hot climates.

    Abstract: This paper proposes an empirical investigation of the impact of social relations, referred to as structural social capital, and cultural values, referred to as intangible cultural capital, on tribal agricultural production in New Caledonia. By using microdata from an original survey on tribal communities, we construct a simultaneous equations model to explore the mechanisms by which cultural values and social relations interact with agricultural performance. Several original findings emerge from this study. First, agricultural performance (production and yield) is a result and, simultaneously, an explanatory factor of social relations, highlighting the limited substitutability between these two sources of wealth (agriculture and social capital). Second, cultural values appear to be an explanatory factor of tribal social relations and thus indirectly affect economic performance. Moreover, our results suggest that the complementarity between the forms of capital is essential for the extensification—maintenance/scaling up—of tribal agriculture (crop production) and even more essential for the intensification (performance, i.e. crop yield) of this activity and the persistence of social ties. Our results thus show that the neoclassical hypothesis of perfect substitutability between the components of wealth is not valid for socioeconomic sustainability.
