|dc.description.abstract||Built environment (buildings, bridges, dams, highways...) is facing a dramatic increase of deterioration cases worldwide, mainly due to the lack of proper inspection and maintenance. Maintaining the safety and serviceability of the infrastructure assets is of crutial importance for the owners/stakeholders, and the society in general, but at the same time still limited resources remain available to this end. Academics, professionals and owners involved in the management of the built infrastructure have taken positive steps to develop more comprehensive measures and conduct better maintenance activities to better invest the limited funds. However, correct funding policies require a proper knowledge of the deterioration and damaging processes involved in the aging buildings. To this end, the series of conferences devoted to the Durability of Building Materials and Components (DBMC) have provided an excellent state of the knowledge and advancement since many years on the subject of durability and performance of the built environment. In fact, along more than 40 years, the main focus and topics of the different conferences have evolved according to the evolution of the existing and the appearance of new problems to be faced by the architectural/engineering community regarding durability of the construction assets. Following the success of previous conferences, the 15th International Conference on Durability of Building Materials and Components (DBMC 2020) held in Barcelona from 20th to 23th of October 2020, covered all major aspects related to durability, from the more traditional ones such as building physics and durability, service life prediction, durability of historical buildings, to the most recent requiring the attention of the construction community as life-cycle assessment and sustainability, BIM technology and durability, and the influence of natural hazards and climate change on the durability of new and existing structures. Also new in this conference is the creation of awards to the student´s contribution (best paper, best poster and best oral presentation) and the launching of a grant for non-profit organizations of students in a projects contest for funding collaborative projects related to built infrastructures in developing countries.
