In addition, on the upper floor there is a bar that allows access to a square that becomes a natural extension of the activity spaces of the building and at the same time serves as a viewpoint towards the landscape of the Collserola park.
The homogeneity of the ceramic material on the facades generates an abstract and silent volume that blends into the natural space of the place.
Description of project by Bayona-Valero Associated Architects and Cantallops-Vicente Architects
CASAL DEL BARRIO IN THE TRINITAT NOVA BARCELONA
The building emerges from the Urbanization, taking advantage of the topography of the street to generate a new lookout plaza at the end of the walk. It blends in with the place, its materials and the construction techniques used and seeks maximum integration and respect for the existing space.
From the upper level is a square that hides the entire program below. The interior space is illuminated from a zenith through perimeter skylights that emerge to the surface in the form of benches and planters.
The square and its roofs thus become natural extensions of the activity spaces of the casal while serving as a viewpoint towards the landscape of the Collserola park.
The homogeneity of the ceramic material for the facades of the entire building becomes latticework in the windows, generating an abstract and silent volume that is integrated into the natural space of the place.
The Bar volume and the double height multipurpose room are the only two volumes recognizable from the upper level.
The main entrance to the equipment is generated on the lower level with a large multipurpose hall space that invites all other spaces: two workshop rooms that can be divided into four, with mobile acoustic panels, a kitchen workshop room and two spaces for musical rehearsal. It is a versatile building that allows different possibilities of adding functions. It is specially designed to work from a self-management model.
This ensures that the new functional program acts as a driving force for the equipment and energizes the social activity of the neighborhood in the environment closest to the building.
CONSTRUCTION AND MATERIALS
Perimeter reinforced concrete walls that together with metal pillars inside support a large 40 cm concrete slab. The Clinker piece covers both floors and facades, leaving a generous air chamber where about 25 cm of insulation of NATURAL RECYCLED FABRIC type GEOPANNEL PYL 40 adheres.
Windows and balconies are made of Flanders pine wood for both interior and exterior finished with lasur.
The interior finishes combine ceramic flooring and some coverings with those clad with OSB-type recycled wood. Ceramic is also used to create absorbent walls that help improve the acoustic behavior of teaching rooms by reducing the reverberation effect.
STRUCTURE
The structure is mostly made of reinforced concrete. Steel pillars are also included in the most open area of the building. The stone construction that guarantees the concrete contributes substantially to gain thermal inertia and improve the climatic behavior of the building. The Forged of the square is a solid slab 40 cm. The forged multipurpose room is made of hollow core slabs with spans of over 7 m.
SUSTAINABILITY
The building is designed to be able to reduce to the maximum the energy demand for consumption. Since the initial phase of the project, we have acted in the combination of different design strategies that contribute to this purpose.
- Demand reduction; form factor and passive measures
The semi-buried building reduces the indoor / outdoor exposure area of the perimeter, reducing energy losses and taking advantage of the thermal inertia of the ground as a natural insulator.
The design of a watertight enclosure with significant thicknesses of perimeter insulation contributes to the good thermal behavior of the interior volume. Ceramic lattices also help to avoid direct solar radiation inside, which penalizes the climatic behavior of the building in summer.
- Optimization of the air conditioning system
The building incorporates a geothermal production system with a total of 14 wells at a depth of 140 m. It also incorporates air recuperators in the renovation system and a field of rooftop photovoltaic panels linked to climate consumption.
With all this, the building obtains the A energy rating seal, with minimal energy demand and very low energy consumption for its use.
Materials such as recycled natural wool for insulation, OSB recycled wood for interior finishes, paints and coatings... Prioritize recycled source materials, from sustainable sources and with certified ecological seals that reinforce the commitment to the environment and CO2 consumption.
