Dynamic dwellings as innovative, sustainable renovation concept
Due to the ever more strict energy performance requirements, the cost of house renovations has increased significantly and also the extra material use for these renovations result in a higher embodied environmental impact. However, the house size is hardly ever taken into account in the evaluation of energy and environmental performances, although houses in Flanders are on average much larger than in the neighbouring countries. Meanwhile, during design phase, houses are often considered as static concepts. And although the attention for changing use during the different life phases of the occupants is increasing, the spatial design for and use along the different seasons is considered invariable. Also the changes in the built environment surrounding the dwelling due to societal changes remain absent in the design process. Currently within the domain of spatial planning there is a lot of research on compaction, but, in Flanders and our neighbouring countries, there are also regions where shrinkage of the population and the housing needs occur. This context is seldomly taken into account. The aim of this doctoral research is to investigate through research by design and quantitative research if, within a context of shrinkage, existing houses can be renovated into dynamic housing and living concepts, in which the occupied and climatised volume and floor area vary along the seasons, but guaranteeing an optimal housing quality. Furthermore aim is to investigate if such housing concepts will result in cheaper, cost effective ZEB houses that have a lower environmental impact. This doctoral research is part of a research project of the research group Arck. This project consists of three PhD positions all addressing spatial issues of rural shrinkage.
