ABSTRACT

ABSTRACT In France, LCA began to be applied in the building sector in the 1990s and a common framework was sketched in the European project REGENER in collaboration with German and Dutch partners. Twenty years later, LCA is being integrated in the next regulation planned for 2018. This communication presents the modelling issues addressed, international exchange and comparison of tools, and proposes perspectives for further work. From the beginning of its development, the life cycle simulation model EQUER has been associated with energy simulation. Dynamic simulation was later applied to the electricity system, including production and power grid, in order to account for temporal variation of the production (according to the season, the day of the week, the hour). A consequential approach was compared to attributional LCA, considering marginal instead of average production processes. Due to the long life span of buildings, prospective aspects were also studied.
