Pecquenchanvre project

Based on the figure of the "occupant", taken here as a full-fledged "actor" in energy renovation approaches based on biobased materials (hemp concrete), the Pecquenchanvre project aims to question, objectify and explain perceptual changes, particularly those relating to comfort, among occupants of renovated housing. This in a broad temporal perspective including the "before-during-after" sequence of the work.

Objectivize changes in occupants' perceptions of comfort in energy-efficient mining housing

Using an SHS approach, the Pecquenchanvre project, whose field of application is the Pecquencourt district, aims to understand, in a retroactive logic, the inter-influencability of energy renovation processes and those linked to perceptual changes in comfort (thermal, spatial and visual) among the occupants of renovated housing. Our starting point is the assumption that, for a project owner (social landlord, etc.), an approach to energy-efficient renovation of its real estate assets is not limited solely to the technical intervention involving the various works to be implemented. In addition to this "actional" dimension, there is another "human" dimension to this interactional game, aimed at understanding the "user journey" to better meet their needs and expectations. It's a journey that takes place over time, and includes what happens, socio-cognitively, to/in the user "before-during-after" the work. In this respect, we pay particular attention to the occupant's degree of involvement, in order to gain a better understanding of his or her perception of comfort. It is in this sense that the concept of "engaging communication" is at the heart of our scientific approach, implemented with/for the occupants of renovated homes. Our ultimate goal is to develop a decision-making tool that objectifies "occupants'" perceptions of comfort, to be used by building owners in their future energy renovation projects.

A multidisciplinary project involving a consortium of universities and professional partners

The Pecquenchanvre project is led by social landlord Maisons & Cités in response to a call for FRATRI (Fonds Régional d'Amplification de la Troisième Révolution Industrielle) projects. Various partners, both academic and professional, are involved: The LARSH laboratory at Université Polytechnique Hauts de France and INSA Hauts de France, the Transition Explorers Chair at Université Catholique de Lille, Opun, CD2E, Cerema, La Callade (Economiste de la construction).
