ABSTRACT

Living walls and other vertical green infrastructure on building surfaces provide regulating, supporting, and cultural ecosystem services in the built environment. Green walls can also generate food as a provisioning ecosystem service. This article discusses a pilot study monitoring the productivity of a 7.5 m² outdoor living wall system planted with produce crops during the 2015 summer growing season in State College, Pennsylvania, USA. Irradiance, water usage, and soil moisture data were also collected to assess context and performance of the living wall system during the growing season.
