In this study, we propose a way to develop rapid measurements of the energy efficiency of buildings. We show that measuring transient states during the heating and free cooling of an empty low-consumption house can lead to a rather good estimate of the total heat loss coefficient K and of the apparent heat capacity C of the building. These measurements can be made typically within a couple of days.
Dans cette étude nous proposons une méthode pour mesurer rapidement lʼefficacité énergétique de bâtiments. Nous montrons quʼen mesurant les états transitoires lors du chauffage et du refroidissement dʼune maison basse consommation vide, on accède au coefficient de fuite thermique K et à la capacité calorifique apparente du bâtiment. Ces mesures peuvent être obtenues en un ou deux jours.
