PhD Position in Optimal and Robust Hygrothermal Design of Interior Insulation KU Leuven in Belgium

This PhD position at KU Leuven focuses on the optimal and robust hygrothermal design of interior insulation systems for the preservation of heritage buildings. Hosted by the Building Physics and Sustainable Design section within the Department of Civil Engineering, the research aims to address the challenges of energy-efficient renovation strategies for historic structures, which are crucial for achieving climate neutrality in line with the European Green Deal. Heritage buildings present unique difficulties, especially regarding the safe application of interior insulation, which is often the only feasible post-insulation technique but carries risks such as condensation, frost damage, and mould or wood decay.

The project builds on previous research, including the European Horizon RiBuild project, and seeks to develop a generic framework for the hygrothermal design of interior insulation systems. Both experimental and numerical research will be conducted at the material and component levels. The candidate will characterize hygrothermal properties of traditional and novel insulation systems, including moisture buffering and bio-based materials, and develop new methodologies for their assessment. The research will also focus on the hygrothermal performance of heritage masonry and incorporate field measurements from a state-of-the-art large-scale test facility funded by the Flemish Resilience recovery plan. Advanced AI techniques, such as neural networks, will be used for probabilistic hygrothermal modeling, forming the basis for optimal and robust design strategies that consider climate change impacts.

Supervision is provided by Prof. Evy Vereecken (KU Leuven and Royal Institute for Cultural Heritage) and Prof. Staf Roels (KU Leuven). The candidate will publish research in academic journals, present at conferences, disseminate findings to non-academic audiences, follow doctoral training at the Arenberg Doctoral School, and write a PhD thesis. Teaching assistance within the Department of Civil Engineering and the Master of Conservation of Monuments and Sites is also expected.

Applicants should hold a Master’s degree in Engineering Science (Civil Engineering, Materials Engineering, Architecture, or equivalent) with minimum distinction or proof of academic achievement. The ideal candidate is dynamic, pro-active, critical, creative-minded, able to work independently and in teams, interested in heritage conservation, and motivated for both numerical and experimental research. Good English proficiency is required, and candidates must reside in Belgium or be willing to relocate. Motivation to apply for a personal (FWO) grant is expected.

The position offers a full-time PhD scholarship for one year, extendable to four years after positive assessment. KU Leuven provides a stimulating work environment, flexible scheduling, partial remote work, and access to extensive academic and non-academic networks. Salary and benefits are determined by staff category, with details available on the KU Leuven job site. The anticipated start date is January 2026, with flexibility based on candidate availability. KU Leuven is committed to diversity, inclusion, and equal opportunity, and offers accessibility support for applicants.
