The objective of this research is to decrease the energy and material consumption of TU Delft’s building stock, by providing the university with a refurbishment method. Refurbishments can have a large impact on the energy and material consumption of the Built Environment, as it focuses on the majority of the Built Environment. By designing net-zero buildings that make use of circular building materials, the impact is decreased and worldwide problems regarding energy and material scarcity are addressed.
This thesis answers the following question: What technical (re)design solutions should be used in the refurbishment of a TU Delft building to achieve net-zero energy whilst taking circular use of building materials into consideration? The main topics that derive from and are discussed in this thesis are: method development, refurbishment, net-zero buildings and circular use of materials. The answer to the research question is given by the developed method and the first building proposal. Using this method allows the TU Delft to one by one redesign its buildings to net-zero and circular buildings.
