What is Default Environmental Data (DED)?

As part of the work on the environmental performance of new buildings and with a view to the RE2020 environmental regulation, default environmental data has been developed for construction or decoration products and equipment. They are made available by the Ministry in charge of construction. In the absence of specific data, these default environmental data are intended to allow an as complete as possible calculation of the LCA of a building. These default environmental data shall be used in the absence of an environmental declaration for the chosen construction or decoration product, or equipment (they always include a safety factor in order to cover the uncertainty on the environmental performance of the installed product, in absence of specific data).
