Latest research and technology for a pioneering sustainability project

Hortus sets new benchmarks in sustainable architecture and lighting design. Intelligent sensors ensure that lighting is used only when and where it’s needed — responding seamlessly to daylight, movement, and environmental data such as CO₂ levels and temperature. As a flagship project for sustainability, Hortus shows how technology and responsibility can come together to create a holistic and forward-thinking spatial experience.

SOLENA: Highest standards and sustainability

Shaped by two years of agile collaboration with Herzog & de Meuron and Reflexion AG, SOLENA unites two contrasting worlds into perfect harmony: the quiet elegance of a recyclable glass body and the precise stability of a folded steel core. Designed to integrate seamlessly into any architectural vision, it appears to float effortlessly beneath ceilings of clay, wood, and other natural materials.

HORTUS is designed for a sustainable future

Every detail – from the natural materials to the manner in which light interacts with the space – reflects the vision of a sustainable future. Zumtobel played a central role in developing a lighting solution that fulfills the building's ambitious sustainability goals while simultaneously highlighting the architectural elegance. In close collaboration with Herzog & de Meuron, Reflexion and Senn Resources AG, Zumtobel brought a new luminaire to life: SOLENA.
