St Martí's Primary School forms part of a Multi-facility Municipal Building with an Adult Education Centre and a two storey underground public car-park, in the neighbourhood of Poblenou in Barcelona. With three different activities working simultaneously this building has the goal to reactivate the surroundings and provide a long-time desired public building to the area.
The building has the Highest Energy Rating (Class A), and has won the 2013 Endesa Award as the Non-Residential More Sustainable Building of Spain, for its technical solutions in the facades and roofs construction, both ventilated.
The building is situated in highly dense surroundings where Cerdà's Eixample merges with the Poblenou industrial layout. The dense and complex program (indoor and outdoor), the dimension of the plot, the rigid urban planning rules and the unmodifiable underground position of the car-park, forced a re-think of the standard directives of public schools and how to adapt St.Marti’s to this specific location. The bulk program of the school is located on the ground floor and all the rooves become school’s playgrounds. The proposal alternates with equal importance the voids and constructed areas. Consequently, better use of natural light, ventilation and views over the inner school spaces are made possible.
The construction of two basement floors, dedicated to a public underground car-park, allow us to think of the school as a very big roof, and rethink this as the playground areas of the school. Taking this decision generates a variety of outdoor spaces, such as: patios on street level, porches (transition spaces) connected to these courtyards, vast open spaces on the first floor and a space for an urban allotments on the top terrace of the main building. All these outdoor spaces organise the indoor spaces according to the visual and physical relation with them.
The side street façades are put together in a very heavy and tectonic way, with textured concrete walls and a perforated steel enclosure, forming an abstract pattern. These façades are aparently the most heavy and closed ones, but at the same time are the facades that allow the straight visual relation in-between the street and the courtyards.
In contrast, the rest of the facades are built with an industrialized, dry mounting and fast execution system. These Ventilated type façades have undisputed advantages of heat insulation and soundproofing because air flows in the intermediate cavity. The Ventilated roof surface, which is walkable on, is perfectly adapted to the Mediterranean climate.
The construction of these type of façades and roofs, the sunscreen protection to the south west and the connection to a District Heating and Cooling Urban System (Districlima) build an urban school with the Highest Energy Rating Class (A).

If you had to do it again?
Management systems of the building facilities are complex. Users would need a simpler interface, or a person responsible for building management
Building users opinion
Building users are very satisfied. The school is airy, comfortable and versatile, all spaces have good natural lighting and ventilation.
