Abstract
enThis master thesis focuses on quantifying the potential of a Slowheating practice in student housing at UCLouvain. In the context of a significant climate crisis, reductions in energy consumption related to the residential sector are crucial. The commonly proposed solution is the thermal efficiency of buildings, but such an approach presents budgetary, material, and labor limits, with results significantly impacted by the direct rebound effect. Therefore, developing energy sobriety or sufficiency is an interesting yet seldom-explored avenue. In the student world, this often manifests as a competition, raising doubts about its long-term effectiveness. Slowheating is a heating practice that involves equipping building occupants as efficiently as possible so that they can choose the lowest possible average indoor temperature, thereby achieving significant reductions in heating consumption. In this work, a student apartment was monitored during the winter of 2023-2024, during which occupants chose an average indoor temperature of 15.51 [°C] throughout the dwelling and an average indoor temperature between 15.91 [°C] and 13.54 [°C] in their respective rooms during the two coldest months. This choice led to a reduction in energy consumption between 30% and 51%. The observed behaviors, mainly presence and temperature choice, were transcribed into a building thermal simulation software (TRNSYS) to confirm these results in a representative UCLouvain student apartment. The computer model, which confirms the results obtained during the experiment, shows that practicing Slowheating only in common areas or only in rooms is equivalent and highlights that the Belgian regulatory PEB insulation achieves strictly inferior results.
