dc.description.abstractGreen infrastructure for buildings, such as extensive green roofs, can improve the urban environment. Previous experimental studies confirm the benefits of these systems from different approaches: energy, hydraulics, materials, etc. But, it is necessary to obtain data about its behaviour in real cases, where conditions could be very heterogeneous: different surface finish, low vegetation cover in first years, lack of maintenance, etc. In this article, different aspects about this topic are discussed. Moreover, the results of monitoring a real extensive green roof during the first year after plantation in order to study the thermal behaviour are presented. In these conditions of low plant cover (10 %), the main conclusions refer to the substrate, which although it preserves cool near the base roof, it heated and cooled very quickly. This fact confirms that the substrate limited thermal mass effect, due basically to its composition and small thickness. The material composition and the thickness of the substrate should be studied in depth because it can affect the thermal performance of the roof.ca_ES

The authors would like to thank the architect Josep Maria Puigdemasa for his provision of information about the renovation project. The authors would like to thank the Catalan Government for the quality accreditation given to their research group (2009 SGR 534).
