This paper introduces some challenges involved in assessment of service life and durability in the context of circular economy principles. It proposes a possible agenda for service life planning in a resource-constrained economy. Aspects considered include the reuse of materials and components over multiple life cycles within built assets. The interface between life cycle assessment and costing techniques, service life planning, and resilience against changing climate and performance requirements is considered. The current codes and standards, in particular within ISO 15686 series on service life, CEN 15643 on integrated sustainability assessment, and ISO 20887 on design for disassembly, are briefly described together with some implicit challenges. The contributions of CIB Task Groups are also considered, in particular CIB Task Groups 16, 39, and 115 and CIB W80 on prediction of service life of building materials methodologies. Several current EU research and development projects are briefly mentioned, in particular BAMB (Buildings as Material Banks). Keywords: circular economy, service life, durability, discount rate, ISO 15686, reuse, disassembly, life cycle, sustainability, climate change, EN 15643. Dans ce document, on presente quelques enjeux lies a devaluation de la duree de vie utile et de la durability dans le contexte des principes d'economie circulaire. On propose la possibility d'un programme de planification de duree de vie utile dans une economie ou les ressources sont limitees. Les aspects pris en consideration comprennent la reutilisation des materiaux et des composants sur plusieurs cycles de vie des biens construits. On prend aussi en consideration l'interface entre devaluation du cycle de vie et les techniques d'etablissement des couts, la planification de la duree de vie utile et la resilience comparees aux changements du climat et consequemment des exigences de rendement. Les codes et normes actuels, en particulier dans la serie ISO 15686 sur la duree de vie, CEN 15643 sur devaluation integree de la durabilite et ISO 20887 sur la conception pour le desassemblage, sont brievement decrits ainsi que quelques enjeux implicites. Les contributions des groupes de travail du <>(CIB) sont egalement abordees, en particulier les groupes de travail CIB 16,39,115 et CIB W80 sur les methodologies de prevision de la duree de vie utile des materiaux de construction. Plusieurs projets actuels de recherche et de developpement de l'UE sont brievement mentionnes, en particulier BAMB (<>).

It has increasingly come [...]
