At the 2023 Architectural Ceramic Assemblies Workshop in Buffalo, New York, our façade engineers were part of a team that developed a prototype for a curtain-wall-supported green screen-wall system that promotes moss growth on terra cotta. Moss has many eco-friendly properties, such as exceptional carbon-sequestration, water-retention and air-filtration capabilities, and it readily adapts to varying ecosystems. And root-free moss requires less maintenance than green walls that use other plants.
