While part 2 below covers a few case studies, please see part 1 of this post, published last week, for more on the scientific underpinnings of living walls.
Living Walls in Workplaces
For corporate workplaces where people spend a significant amount of time inside, living walls could vitalize the working environment, add aesthetic pleasure, and play important roles in positively impacting people’s health. According to a scientific report published by Nature, urbanization in Western cities has resulted in a lack of exposure to environmental microbes due to the increased level of hygiene, loss of biodiversity, and irregular contact with soil, which has been linked to many immune mediated diseases. Indoor green walls in urban offices can affect health-associated commensal skin microbiota and enhance immune regulation among employees [1]. Indoor plants in the workplace were found to correlate with less sick leave, better task performance, and quicker restoration from mental fatigue [2-3].
Workplaces are embracing the idea of bringing nature inside through living walls that maximize space utilization and provide numerous biophilic features. Living walls help to achieve many goals as required by the WELL Building Standard—Air, Water, Nourishment, Light, Fitness, Comfort, & Mind [4]. Duolingo, a leading tech company in the language education industry, has recently integrated several green walls that have become new attractions in their Pittsburgh, Pennsylvania headquarters.
Recent technology development makes living wall structures more flexible and designable beyond “just a green wall.” GBBN Architects’ Cincinnati office experimented with digital fabrication and augmented reality (AR) technology in their living wall design and installation. According to an interview with the living wall designers Mandy Woltjer and Troy Malmstrom, the design concept was to encourage plants to grow out of an irregular trellis that increases multi-dimensional volumes. Therefore, the plants were installed first in an AR space where the designer could precisely locate the plants in the designated position.
