The SDE19 contest focuses on the renovation of existing apartment buildings. Team Ghent University will focus on the renovation of large- scale apartment buildings in the Belgian context, where contractors such as Etrimo and Amelinckx were responsible for a mass production of collective housing in the fifties, sixties and seventies in the suburban zones. Although these buildings have an interesting urban location, surrounded by a green environment, a nice view and affordable apartments; today these high-rise buildings are typically outdated and don’t longer meet code requirements in terms of e.g. fire safety, thermal and acoustical performance. Renovating these apartments can solve these problems.
