smog-eating façade realized with iris ceramica group active surfaces®

Progetto CMR enhances Iris Ceramica Group’s Active Surfaces®

In the heart of Milan’s resurgent Garibaldi-Repubblica neighborhood stands a beacon of sustainability: De Castillia 23. Once a dormant structure for 15 years, the complex has now been dubbed a smog-eating building, thanks to the visionary renovation by Progetto CMR and their use of Iris Ceramica Group’s Active Surfaces®.

progetto CMR renovates de castillia 23

At the core of the transformation of De Castillia 23, owned by Gruppo Unipol, lies Iris Ceramica Group (see here)’s innovative technology: eco-active Active Surfaces®. Originating in 2009 yet building upon the Group’s six decades of production and material expertise, these surfaces signify a continued commitment to the well-being of both built and natural environments, not only in terms of high performance functionally but also in style.

innovative Active Surfaces® properties

By harnessing the power of light, the material boasts an impressive array of properties: antibacterial and antiviral, anti-pollution, anti-odor, and self-cleaning. Certified to ISO standards as well, they offer not only aesthetic appeal but also a shield against harmful pathogens and environmental pollutants. They can eliminate up to 99% of bacteria and viruses, from the most common to the most dangerous and antibiotic-resistant.

Active Surfaces® properties are antibacterial and antiviral, anti-pollution, anti-odor, and self-cleaning

Progetto CMR’s renovation for De Castillia 23 aimed to enhance the functionality, energy performance, and overall efficiency of the complex, which comprises two buildings. The choice of Active Surfaces® was pivotal to the sustainable and human-centric design. The ceramic slabs adorn the façade, balcony flooring, and external areas.

A significant aspect of the regeneration design was the construction of a prismatic façade with triangular-shaped glass walls. This creates a dynamic movement from different angles based on lighting, enhanced by a lighter background surface reflecting light against a darker color. Active Surfaces® materials by Fiandre Architectural Surfaces were chosen and installed using the Granitech ventilated façade system.

The beauty of Active Surfaces® not only combats grime but also pollution. Firstly, the material aligns with the project’s green philosophy, as they are made from recyclable materials. These slabs are dirt-repellent, enabling the façade to be cleaned with water and mild detergent. Moreover, they act as a shield against nitrogen oxide, mitigating up to 59kg/year and benefiting the surrounding neighborhood.

the innovative materials were also used for the building’s interiors, such as for the office and bathroom spaces

The integration of the material has also transformed the building’s interiors, making them hygienic as well as practical. From office spaces to bathroom application, these surfaces offer a combination of anti-slip properties and ease of cleaning, enhancing safety and comfort for occupants. Large balconies, bathed in natural light, not only brighten the office spaces but also offer respite from the summer heat and a sense of connection to the outside.
