This thesis aims to develop robust refurbishment strategies for the residential-building stock. This is achieved by conducting a full-factorial robust-optimization for load-management-potential and energy- demand. The final strategies are based on data from more than 200 000. simulations, which cover the most influential design-parameters under seven uncertainty-scenarios.
The following main findings have been made in this study. The developed refurbishment-strategies increase load-management-potential up to 122% and simultaneously reduce energy consumption by 56% compared to non-optimized buildings.
The highest impact has been identified in the replacement of radiators by underfloor heating. Thus, a more than two-fold increase in load-management-potential can be unlocked at reduced energy demand.
Maximum refurbishment efficiency can be unlocked in uninsulated buildings. Upgrading the walls with an insulation layer of 4 cm, installing double glazed windows and exchanging the heating system by underfloor heating unlocks the maximum potential. An even higher load management potential can be achieved at the cost of energy demand if no refurbishment of the facade is conducted. This identifies especially listed buildings as target group.
The given study is of particular interest for researchers, who focus on the load-management-potential of buildings. Furthermore, it may act as a decision support tool for planners, since actual refurbishment strategies are provided. Additionally, the extensions implemented to TRNLizard as well as an optimized parallelization-methodology are of general interest to all researchers conducting optimization-studies with TRNSYS.
