The Grenoble case study illustrates architectural value and cultural heritage as an integral part of its design characteristics inherited from its original construction and continued in its renovation. In addition, spatial quality assessment is used to understand the positive and negative effects of renovation. Spatial quality is defined here as the excellence of the space in terms of views, privacy, lighting, spatiality, transition between public and private domains, and perceived, built, and human densities.
The Grenoble case was chosen as a test case for the spatial quality evaluation methodology, as this demonstrator represents the most substantial physical changes in building mass among the ZenN demonstrators. The dwelling renovation significantly changed a large range of building characteristics such as external and internal walls, facade composition, built area and plans. A detailed assessment of the physical changes in spatial quality as a result of the dwelling renovation was carried out.
The results of the spatial quality assessment (Acre & Wyckmans, Forthcoming) of the MS-1 building in Grenoble indicate that spatial quality is mainly positively affected by the dwelling renovation. Particularly views from the dwellings to the outside as well as internal spatiality are expected to be improved after the renovation. However, there are some points of alert in the results. The renovation of the building component of floors scores low in the assessment indicating a negative effect of the renovation on spatial quality related to some aspects of internal spatiality. This is because the ceiling height of 2.50 m will be lowered to 2.35 m after the renovation.
In the next steps, the potential for adaptation to climate change will be integrated into the taxonomy for both technical and non-technical drivers and be presented in the later deliverable presenting an holistic design kit for nZEB renovation.
