General Information
The building is conceived as a suspended volume through which the landscape and its topography flow freely.

The project proposes an open spatial system, not predefined. The interior spaces are flexible, prepared to accommodate future changes of use.

By elevating the building, the ground is returned to the landscape, enabling ecological continuity, natural water management, and the activation of the lower space as climate infrastructure. This green urban realm acts as a passive thermodynamic system that contributes to thermal regulation, improved comfort, and reduced energy consumption.

Location and Site
The project is located on a portion of natural land framed by the intersection of streets that today form the urban grid. It consists of four plots whose surface still preserves part of the vegetation and topography characteristic of the former marshlands of the river delta.

The surrounding urban development has its ground level above the natural terrain, forming a natural basin, like a unique campus for which our building sets the tone.

Exteriors
Access to the building takes place through an underground lobby, completely detached from the upper volume, beneath a landscaped mound.

Panoramic elevators collect the flow of people from the entrance, ascending freely to the upper volume where the offices are located.

The building can be experienced as a walk. Exterior staircases connect the levels and landscaped paths on each floor, leading to the entrance of every office unit.

The suspended volumes feature a porous and terraced morphology. Porous, through courtyards that modulate interior lighting and ventilation. Terraced, with outdoor surfaces on every level that multiply, vertically, the conditions of a ground floor.

The overall appearance expresses an ambivalent presence. On one hand, it evokes the atmosphere of the pre-existing delta landscape through the chromatic vibration of its envelope; on the other, the built volume responds to the Cartesian urban frontage of the adjacent city, completing and qualifying the urban space.

The façade is 100% industrialized, composed of a multitude of colored metal elements that filter and reflect solar radiation, providing diffused light inside the offices. It integrates into a concrete structure resolved in three levels coordinated by different contractors who share support elements to optimize resources and reuse substructures. This stratified system allows precise execution, reduced construction time, and minimized waste. The use of digital control processes, assembly templates, and detailed work sequencing ensured coordinated execution with minimal errors.

Interiors
The proposed morphology, combined with the building’s exterior circulation routes, allows for great flexibility and versatility of use.

The interior emerges as a sequence of generous functional spaces with optimal light and climate conditions. These spaces form an efficient infrastructure capable of responding to a diversity of potential uses.

The outdoor terraces on each level have been designed as extensions of the interior workspace. The configuration of the platforms in relation to circulation routes, together with the appropriate use of Smart technologies, enables the proper management of outdoor spaces among the building’s user community.

Bioclimatic Strategies, Sustainability and Circular Economy
Contemporary architecture faces a paradigm shift: designing buildings that not only reduce environmental impact but also preserve, store, and reactivate material, spatial, and energy value over time.

Natural Comfort
The natural comfort strategy is based on bioclimatic principles that take advantage of the building’s orientation, cross ventilation, and solar control to minimize energy demand. Through thermal inertia and appropriate solar protection, indoor temperature is stabilized and overheating is prevented, especially in a warm-humid climate. Natural ventilation promotes heat dissipation and improves indoor air quality, creating healthier and more comfortable spaces without excessive reliance on active systems.

In terms of daylighting, the project achieves an SDA of 62%, meaning that a significant portion of occupied areas receives adequate natural light levels for much of the year. Meanwhile, an ASE of 100% indicates the absence of excessive direct solar exposure, avoiding glare and unwanted heat gains thanks to shading and solar control elements that optimize the balance between daylight contribution and thermal comfort.

Together, these strategies create an efficient, stable, and high-quality indoor environment.

Biodiversity
The biodiversity strategy is based on integrating a wide variety of Mediterranean species adapted to the local climate, prioritizing resilient, low-water-consumption, and low-maintenance plants. The building is partially elevated to allow vegetation continuity underneath, maintaining ecological connectivity and reinforcing the existing landscape. This decision increases effective green surface and reduces the urban heat island effect through evapotranspiration and natural shading.

A water pond is incorporated as a microclimatic regulatory element, promoting passive cooling through evaporation, increasing ambient humidity during dry periods, and acting as a sustainable irrigation reservoir. It also enhances biodiversity by attracting birds, pollinators, and small local species. Soil permeability and natural rainwater management are improved, reinforcing hydrological balance. Vegetation and water work together to create a cooler microclimate, reduce cooling demand, and improve air quality through CO₂ and particle capture.

Energy Management
The energy strategy began with demand reduction through the development of a detailed building energy model (digital twin), enabling thermal behavior analysis and identification of heat losses and gains throughout the year. Envelope optimization, solar protections, and wind simulations for the bioclimatic courtyard were implemented.

The building achieves an annual energy demand of 55.39 kWh/m², representing a 38% reduction compared to a reference building. Efficient lighting, CO₂ and lighting sensors, photovoltaic panels, geothermal and aerothermal systems further reduce consumption, resulting in a 53.1% reduction in total energy use compared to the baseline.

Water Management
The water strategy includes green terraces with water retention capacity and a sustainable drainage system that channels rainwater to a visible reservoir for irrigation reuse. High-efficiency sanitary fixtures reduce interior consumption. This approach minimizes potable water demand, improves rainwater management, reduces emissions associated with water treatment, and lowers operational costs.

Material Resource Management
The material strategy aims to significantly reduce embodied carbon, minimize resource consumption, and ensure component recovery at end of life, aligned with European Taxonomy, LEVEL(s), and LEED. The building is conceived as a reversible, adaptable infrastructure designed under Life Cycle Assessment (LCA) criteria. It achieves a 48% reduction in embodied emissions and 35% circularity potential compared to baseline values.

Climate Change and Resilience
The project integrates mitigation and adaptation measures to address present and future climate scenarios. Vegetation, green roofs, optimized envelopes, and efficient water systems strengthen resilience against heat waves, extreme temperatures, and droughts. The building positions itself as a benchmark in energy efficiency, water responsibility, sustainable material selection, and environmental comfort, reducing operational costs and environmental impact over its lifetime.
