Global infrastructure and renewable energy leader ACCIONA’s new international headquarters in Madrid has set a new standard in sustainable and hyperconnected workplace design. Located on a 10-hectare site in a central Madrid district, the workspace interiors were designed by interdisciplinary architecture and design firm Perkins&Will to reflect ACCIONA’s commitment to sustainability, innovation, and well-being.
The project repurposed the site of a decades-old corporate campus, reviving the location with a verdant landscape and new facilities for 4,000 employees. The campus features three office buildings, including a new one designed by Fenwick Iribarren Architects with interiors by Perkins&Will, along with an auditorium and other amenities. Two of the original buildings underwent deep refurbishment, with Perkins&Will’s interior designs creating light-filled, forward-thinking environments that work with the existing structure and materials.
The ACCIONA Campus reflects the company’s commitment to sustainability, innovation, and people. Designed as a benchmark for the offices of the future, it brings together ACCIONA’s global expertise in renewable energy and infrastructure to create a workplace that fosters collaboration, creativity, and well-being. The Campus integrates advanced technology and sustainable design to inspire employees to reach their full potential while contributing positively to both business and the planet.
Designing for well-being and connection
The campus prioritises human experience and cross-disciplinary collaboration, featuring flexible workspaces, coworking zones, and event areas that blend efficiency with hospitality. Interconnecting staircases and communal areas promote movement and spontaneous interaction, while external pavilions and terraces offer shaded retreats with fresh air and panoramic views. Dedicated zones for quiet reflection, optimised lighting with circadian rhythms, and enhanced acoustic and thermal comfort support mental clarity and physical vitality.
The interior design contrasts raw textures such as concrete, galvanised metals, and masonry with refined materials, harmonising old and new. A restrained palette of white, wood, and reflective surfaces references vernacular Spanish architecture, creating a serene and luminous atmosphere that celebrates the interplay of light and shadow.
Architectural interventions bring daylight deep into the floor plates, minimising reliance on artificial lighting and enhancing visual comfort. Organic, sculptural forms set against the Iberian light create dramatic chiaroscuro moments, infusing the spaces with an ethereal yet warm ambience.
Innovation and sustainability at every level
The campus meets the highest environmental standards, achieving LEED Platinum and WELL Platinum certifications while aligning with EU Taxonomy. It operates entirely on renewable electricity, with on-site solar PV, geothermal systems, and heat recovery technologies. Modular design allows for adaptability and waste reduction, locally sourced timber and antimicrobial metals enhance sustainability, and ACCIONA’s own low-carbon materials are featured prominently. Technological advancements include 3D-printed joinery, bespoke ceiling fans developed with ACCIONA’s innovation lab, and robotics that support security and logistics.
A regenerative landscape rooted in ecology
The landscape design, commissioned by ACCIONA, reflects a commitment to ecological restoration and employee well-being. Historic pine groves have been preserved and expanded, with 1,000 new trees and 20,000 shrubs planted. Native, climate-adapted species were prioritised to require minimal water. Rainwater reuse and greywater recycling systems support sustainable water management, while native meadows replace extensive lawns and improve soil health, reduce erosion, and unify the landscape. The result is a campus that not only enhances the well-being of its people but also regenerates the environment.
