Show moreMaterial circularity and energy efficiency are highly relevant and intertwined issues for the transition towards a carbon-neutral and circular built environment. In the Netherlands, the building sector has been rendered a priority towards a circular and low-carbon society. This thesis explored potential solutions for these twin issues in light of a novel technological system. This system presents an energy–material efficiency solution for energy renovation of building stocks with prefabricated concrete elements (PCEs) with recycled CDW as feedstock. Life cycle assessment (LCA) and life cycle costing (LCC) were combined with dynamic material flow analysis (MFA) to estimate the economic and environmental implications at both a product level and a national level.

Show moreWe constructed a G-zip over the special fiber of Kisin's integral canonical model. This induces a morphism from the special fiber to the stack of G-zips. Fibers of this morphism are Ekedahl-Oort strata. We proved that this morphism is smooth, and hence we can transfer results about geometry of the stack of G-zips to results about Ekedahl-Oort strata. In particular, each stratum is smooth, and we know its dimension and closure. Show less
