Modélisation du parc de bâtiments du secteur tertiaire et simulation énergétique

Abstract : Energy efficiency and decarbonation of energy use in the building sector is a strategic issue of the ecological transition in France. In 2019, the French building stock accounts for 45% of the final energy consumption, with the tertiary sector alone accounting for about one third of this or 17% of national consumption. The energy consumption of the tertiary stock and its determining factors are poorly documented. Existing tertiary stock models are mostly based on an aggregated representation of the total heated surface of the building stock subdivided by its economic activity and heating energy fuel. This aggregation makes it impossible to represent the extreme heterogeneity of the sector. This work aims at reconciling different accessible databases to establish a tertiary building stock model, its consumption and its load curve. The developed method allows to represent the building stock as a collection of buildings, in which each of them is characterized individually in terms of area, constructive and thermal characteristics, occupants, main activity sector and equipment. This method allows to take account of the link between building, system and occupancy, which contributes to the heterogeneity of the tertiary sector. The methodology is designed to be applicable to any territory in metropolitan France. The results of surface area modelling and energy consumption simulation could thus be compared with existing references for the Île-de-France region. Two applications of the method are presented: the study of the energy saving potential of the tertiary sector in the Île-de-France region, and the study of photovoltaic self-consumption in the tertiary sector for the agglomeration of Orleans.
