Possible effects on the built environment are identified as urban heat stress, air pollution, extreme weather conditions, etc. As a result, there is an increase in disease and mortality specifically in the cities among the vulnerable citizens such as elderly people and children. Moreover, many cities worldwide are in the evolution of urbanization which leads to increased carbon emissions as well as a demand for more material production and waste. Consequently, the construction industry embodies great potential for reaching the energy and carbon mitigation goals. For regeneration of the built environment, the European directives requires for the renovation of existing building stock as quick as possible. In Flemish context, cities stimulate renovation projects on a systematic and planned basis, by defining 'urban renovation districts' which received special financial facilities and subsidizing. Consequently, there is a growing demand for affordable housing in combination with a shortage of qualitative and energy efficient housing opportunities. In the last decades, there has been an intensive effort to develop different retrofit strategies, but there is a lack of comprehensive approach that delivers innovative technical solutions such as circular and bio-based construction methods as a solution to the increased housing demand of vulnerable people. For this purpose, this study combines the efforts of two initiatives, (1) Interreg Circular Bio-Based Construction Industry (CBCI) and (2) the innovative financial policy instrument of subsidy retention for low-income groups (refers to citizens living in poor quality houses with insufficient economic means & social skills to renovate). The study has the ambition to explore the coherence between technical, economical, legal, social aspects for circular urban retrofit strategies. Circular building materials and methods were developed and tested in real-life setting with construction of a prototype living lab (LL) in Technology Campus, Ghent. Depending on the results from the LL, an urban renewal strategy for Flemish districts is proposed by using subsidy retention on macro-economic and social level. The scenario is envisaged as a collective approach with the local community in which the vulnerable users also benefit as direct participants to the research.
