This internship is part of experimental campaigns during which building occupants were asked to evaluate their own thermal comfort. These campaigns were carried out in tertiary buildings used for offices, mainly during summer periods. In parallel with these campaigns, several prototypes of an advice solution for occupants were deployed, with the aim of advising them on the best action to take on the openings (windows) in order to improve their own thermal comfort and the quality of air, while seeking to minimize energy consumption. In coordination with the project team, the candidate will have to carry out the following missions: analysis of data acquired during the experimental campaigns and calculation of comfort/performance indicators, preparation and monitoring of new experimental campaigns to evaluate the comfort, preparation and monitoring of new experimental campaigns to deploy the occupant advice solution, improvement of the advice solution based on the analyzes carried out.
