About the project

The Institute of Energy and Environment at the HES-SO Valais–Wallis is seeking a motivated PhD candidate to join the European project PRISE, focused on Positive Energy Districts (PEDs) and their role in climate-neutral cities.

The research will combine technical modelling and social dimensions. On the technical side, the PhD will explore how to integrate energy vectors (electricity, heating/cooling, energy storage, renewables) and sustainable mobility options (active mobility, EVs, electrified public transport) to optimize PEDs under demand response and grid constraints. On the social side, the work will address governance and community engagement.

The approach will be tested in Ostend (Belgium), with possible extension to Sion (Switzerland). The candidate will also contribute to:

This PhD offers a unique perspective on urban energy transitions, combining advanced modelling with interdisciplinary methods. The doctoral candidate will be enrolled at EPFL and jointly supervised by the HES-SO Valais–Wallis.
