Creating a circular economy within the built environment is vital to achieve a more sustainable society. By replacing building components with more circular ones during new construction, maintenance and renovation, we can gradually create a circular built environment. There are many different possible design variants for circular building components. Yet, knowledge on which variants are the most most circular, and which are feasible to implement is lacking. In this dissertation, we aimed to d...

The neglect of significance, deterioration and consequent devaluation of the post-war mass housing neighbourhoods are major challenges, both in the field of heritage conservation and management and in urban planning and design. The reasons for their deterioration are different, and interlinked with the socio-cultural discourse, as well as the spatial characteristics of these neighbourhoods. This doctoral research addresses the challenges of those neighbourhoods, focusing on New Belgrade Block...

In improving the sustainability of our built environment, European institutions emphasize the importance of protecting and advancing cultural values. As most of the stock is not listed, nor is its heritage significance assessed, future sustainable developments risk neglecting present attributes, causing the loss of resources and their significance. This problem applies to 1965-1985 Dutch housing, comprising over 30% of the stock, with no clarity on its heritage significance. This thesis aims ...

This thesis brings forward the design dimension, and, more specifically, co-design, to the study of housing affordability. Co-design occurs when end-users and professionals work together towards a common goal. It is a process often applied in collaborative housing, an umbrella concept encompassing different housing forms based on collective self-organisation and collaboration, where residents choose to share certain spaces. The aim of this research is to assess if and how co-design processes ...

This dissertation develops an understanding towards governing social sustainability goals into area-based urban development projects. It draws on Amartya Sen’s Capability Approach to construct a capability-centered evaluation of how institutionalized governance processes around these projects ultimately affect people’s freedoms to do the things they value in their urban living environment. Presenting case studies from the Netherlands, Sweden and Austria, the approach adopted in this disse...

The springing up of freeform architecture and structures introduces many challenges to structural engineers. The main challenge is to generate structural forms with high structural efficiency subject to the architectural space constraints during the conceptual structural design process.

Structural Morphology is the study of the relation between form and force, which can be considered the guiding theory for this challenge. The relation between form and force is important for all types of struc...

Population growth and urbanisation trends bring many consequences related to the increase in global energy consumption, CO2 emissions and a decrease in arable land per person. High‑rises have been one of the inevitable buildings of metropoles to provide extra floor space since the early examples in the 19th century. Therefore, optimisation of high-rise buildings has been the focus of researchers because of significant performance enhancement, mainly in energy consumption and generation. Bas...

In recent years, the Private Rented Sector (PRS) has witnessed rapid growth across numerous jurisdictions, with Chinese metropolises notably standing out. Throughout the history of housing policy development in China, the PRS has been largely disregarded. It was not until 2015 that the government proposed the idea of “accelerating the development of the rental housing market” to achieve a “balanced development between home renting and purchasing”. However, the PRS in China is still in...
