Pioneer Case

GREEN Roof in refurbished industrial building

A short description of the NBS project

This project consists of the rehabilitation of an existing building by adding, among other rehabilitation measures, a semi-public green space on the roof with a positive influence on the health of users, positive effects on urban climate against the heat island effect and positive effect on water by it storages in the deck space. It also improves the energy efficiency of the building by the insulation provided by the layers of green cover. Office buildings made for industrial and technological activities, for the new development area in Barcelona, the 22@ area. The area planning required the development of an urban planning that involved the building to meet the requirements of private and public services with innovation criteria, both to the activities developed indoors and to the building image within the city. The joint tries to answers the necessarily regeneration and recycle of buildings and obsolete neighborhoods without the necessity of destroying. Only the structure of the existing building is preserved. The facade is a new skin, double enclosure skin based on bioclimatic criteria for heat contribution and indoors ventilation. The new technological skin expresses the colours, textures and the use of transparencies, therefore the activities involved inside. The roof is projected like a green semi-public space, advisability space. There exists a big hall for multiple uses for conventions, parades and different meetings; a new “level 0” for the coexistence.

Who Started this initiative? Other
Contracting Authority SEATEX: (Community owners) majority owners
Project manager (leader and main partners): entities names, and know-how involved Leader: Tècnics G3 (project manager and quantity surveying) Main partners: Pich Architects (Architects and landscape architects) & Intemper (Integral solutions for roofs and facades)
Who (else) was involved in the project ? (Inhabitants, local association, etc.) Pich Architects offered the solution and the majority-owner (SEATEX) accepted it
More detail on the process and the role of the different stakeholders (How did it happen?) SEATEX ( (Community owners - majority owners), as investors, they controlled the total cost and were the ones who made the final decision about how the refurbishment should be done.
OPTIONAL Considering the actual impacts, who are the primary beneficiaries of the project. The employees of the office located in the building are the primary beneficiaries.
Cluster Governance Model Description
cluster3_private_private_partnershipsNon_State_Market_driven_governanceIn 2000 the Barcelona City Council approved a new urban planning ordinance aimed at transforming the old industrial area of Poblenou, with obsolete factories that had long ago been abandoned or were simply not very productive, into a magnet for new activities. This named 22@ urban planning allows more construction, more public spaces or green areas and subsidized housing as long as the previous industrial activity is replaced by offices or other business services and equipment related to new technology and knowledge. The goal of 22@ is to encourage land owners to update obsolete urban planning elements from the end of the 19th and beginning of the 20th centuries while maintaining economic activity, which would not have happened with a traditional rezoning from industrial to residential designation.
