The first competition winning green roof terrace is completed

Urban green spaces. The green roof terrace on the Salesian school buildings in the Sarrià district is now finished. It is situated on Passeig de Sant Joan Bosco, on a building complex that forms a perimeter enclosure around a large block of houses with two patios on a different level.

It is the first of the ten winning projects of the green roof competition to be completed. The rest of the winning roof terraces from the competition held in June 2017 are currently under construction and are scheduled to be completed over the course of the coming year.

The green roof terrace on the Salesian school buildings in the Sarrià district is now finished. It is the first of the ten winning projects of the green roof competition to be completed. With this roof terrace, the Sarrià-Sant Gervasi district gains 191 m2 of green space.

The Salesian roof terrace is situated on Passeig de Sant Joan Bosco, on a building complex that forms a perimeter enclosure around a large block of houses with two patios on a different level.

These spaces have become passable and accessible and a series of carpeting plants have been planted there, such as lavender, bushes along the railings, and climbing plants on the walls. Altogether they create a visually striking space, particularly from the school’s classrooms.

The project cost some €45,000 to complete and it will be used as a space for practical studies for all students and specifically for students studying for the degree in renewable energies.

The photovoltaic solar panels have been installed by the students themselves, so that, as well as making use of the energy produced, they have become an educational resource.

The completed project also features a drip irrigation system with moisture sensors and an insect hotel that will help to ensure the pollination of the plant species.

More roof terraces in progress

With the Salesian roof completed the nine remaining winners of the green roof competition held last year are in the process of being constructed and are scheduled to be completed over the course of the coming year.

Barcelona City Council launched this competition to promote the introduction of new green roof terraces, and funded the elaboration of 45 technical projects and awarded prizes to 10 green rooftops on residential buildings, educational facilities, healthcare centres and buildings used for other purposes. All of them have a strong environmental, social and landscaping impact.

These 10 private roof terraces, that will add an extra 4,000 m2 of green space, come in addition to the green rooftops previously created on municipal buildings such as the Vall d’Hebron Market, the Forum building, the Zona Nord Library and the Joan Maragall Library, which will enable the municipal commitment, established in the government measure to promote urban green infrastructure, to be met.
