The new headquarters of the Medical Emergency System (SEM) is the result of the public competition organized by CatSalut in 2022, which addressed the challenge of designing and constructing a 21,000 m2 building in just 20 months, with the inherent constraints that this entails. With this ambitious goal in mind, the initial design was based on an industrialized construction system, allowing for a significant reduction in construction times through prefabrication and modularity.
A necessarily compact building (for economic reasons, sustainability, and site constraints) located in the current Duran i Reynals Hospital complex, it balances existing structures and respects the hospital's alignments. It is therefore understood as an additional volume within the current compositional rhythm, reinforcing the complex's façade on Gran Vía. The configuration of the proposal takes into account the future urban plan, proposing a through-entrance lobby that allows for a current and future fit within the campus. The building's functional layout responds to the need for a flexible infrastructure adaptable to change. The building is composed of two clear, parallel programmatic strips: one for the main work spaces, developed in open-plan rooms of 2,000 m2; the other for the auxiliary spaces, which concentrate the services, circulation cores, and secondary spaces on each floor. The structural system generates pillar-free floors in each strip, allowing for maximum adaptability.
A comprehensive sustainability strategy was implemented, with passive and active measures. From the design of adapted facades, where the glass surface on more exposed orientations has protective elements that allow unobstructed exterior views, to the introduction of a bioclimatic patio in the center of the building as a temperate space for workers to interact, and a photovoltaic pergola shading the terrace. Regarding the embedded carbon footprint, the industrialization of the project represents a reduction of 1,032 tons of CO2. The construction solutions were defined taking into account the execution time, construction cost, and durability of the materials, reducing future maintenance costs. Large, continuous precast concrete planters comprise the facades, along with the maintenance walkway, and will provide protection from radiation when the vegetation reaches maturity. They also introduce a beneficial biophilia, friendly to both the city and the worker.
The design also pursues the key objective of creating quality spaces for user comfort: maximizing natural light and exterior views, creating pleasant interior circulation spaces and user interaction spaces around the semi-open bioclimatic courtyard (which avoids the systematic use of elevators), and creating landscaped exterior spaces.
