Neuroscience studies document the positive effects of green walls on human quality-of-life and cognitive function as well as research-consistent best practices.
Powerful repercussions for public space design
The neuroscience research is consistent: design needs to support green leafy indoor plants in whatever ways it can—places where plants can live healthy lives, visible to many, have powerful effects on what goes on in our heads.
Kalla and colleagues evaluated responses to greenery at railway stations. They report that “Previous studies have confirmed the economic feasibility of station greenery and users’ preference for this but also their reluctance to pay for greenery compared to other services. . . . we present the development and implementation of a method using static 2D representations of virtual reality scenes generated from a digital twin. . . . participants were randomly assigned to assess one of three levels of greenery. . . .
Elbertse, and Steenbekkers evaluated the repercussions of various quantities of in-workplace greenery. They report that their “study aims to explore the effect of different volumes of indoor greenery on perceived stress, stress, perceived productivity, productivity and perceived workplace satisfaction to support employees’ well-being. . . . Different volumes of indoor greenery were added to the experiment room (0%, 0.5% and 8%) . . . . perceived stress and heart rate (physical stress) are lower in the 8% condition.
Better not bigger
Chiang and colleagues evaluated the implications of adding green plants along the sides of roads.
