Owner approach of sustainability

All spaces and tours of the center will be accessible. The evacuation routes and the maximum occupancy of spaces for fire safety were re-studied. Areas where noisy activities are carried out are acoustically isolated from aerial and impact noise. Materials of zero or minimum maintenance, with great durability and easy substitution are used. The use of reused-reusable or recycled-recyclable materials that will meet the rest of maintenance and durability requirements will be valued, building solutions should be self-sufficient. Strategies should be proposed to reduce the energy demand in the building more significantly. Consideration should be given to electricity consumption and that the building is expected to reduce total heat demand, be capable of accumulating ACS and have an efficient heating and cooling system. The consumption will be taken into account, and also the material construction of the building. The impact must be computed taking into account the life cycle of the materials.

Architectural description

The façades of the existing building and the roof floor of the ground floor are preserved, the manual revolts and existing metal joists are exposed as a false ceiling and as protection of the new structural wood slab. This part, with some arch and original foundry pillars, conserves and gives continuity to the original appearance of the building of the industrial era of the late nineteenth century. The part of new structure is constructed with wood, contra-laminated or light framework according to the situation. The original central courtyard is recovered, creating an emptiness in the south part of the second floor that allows the central courtyard to be converted into a skylight with lateral light entrance to maximize the contribution in winter and to limit it with its cantilever in summer. This patio allows the entrance of natural light in the center of the building and a general visual relation that allows to understand the building just when entering. Existing openings are maintained except for the central one on the south façade that is widened to increase the passive solar input in winter. All the openings have their solar control system adjustable on the outside with the adjustable blinds or ‘porticones’ with the stamped sheet of the rest of the ventilated facade of the enlarged part.

Building users opinion

Dignification of a space that was very limited and now will have more than 800m2, with multipurpose rooms so that the entities of the neighborhood can carry out activities.

Product category : Acabados / Acabado, aislamiento

The product is used as thermal and acoustic insulation. It is breathable, hygroscopic, recyclable and recycled. Prevents condensation in insulation chambers. It regulates the atmosphere, warm in winter and cool in summer. It is made up of 85% cotton and 15% other fibers. Additives are added to achieve fungicidal and fire retardant properties. It is a product free of toxins and substances that cause allergies.

It is an isolation with which it is easy to work with.

Construction and exploitation costs

• Total cost of the building : 1 000 000 €

Energy bill

• Forecasted energy bill/year : 1 375,00 €

Real energy cost/m2 : 1.99

Real energy cost/none : 105.77

Urban environment

The green area was isolated from the public space by all its limits. On the west side, where the entrance to the building is located, a perimeter fence surrounded the space and only allowed access through a door. On the eastern side, bordering Can Portabella Square, there were walls of work that formerly limited the ownership of the house when this was the house of the master of the industrial area that occupied the space of the current plaza. The proposed urbanization of this space is regarded as the continuation of the Plaza Porta Portabella, eliminating the existing architectural barriers and opening it to public space. To achieve this end, the fence and the walls mentioned above are demolished and continuity is given to the current pavement of the square. The old control house is demolished but its layout is maintained on the pavement of different color, leaving traces of the industrial past of the enclosure. Most trees are preserved, eliminating some shrubs and weeds. The pavement becomes a combination of paving stones and soft beds and adapts to the existing unevenness to facilitate the movement of pedestrians across the square. New urban elements such as furniture or lighting are also incorporated, to make this space, now in disuse, a new place for the neighbors.
