To increase the resilience and liveability of cities and to maintain their productivity, green infrastructure is being highly viewed as a sustainable development strategy. Green infrastructure or technologies, essentially, represent a set of engineered elements providing multiple ecosystem services at building and urban scales. They aim to integrate local water management with urban greening. Examples include biofiltration systems (or raingardens), constructed wetlands, green roofs, vegetated swales and ponds, green walls and living walls (or green façade).

This guide provides critical information on how to design, operate and maintain these green wall and façade systems to maximise their water treatment benefits to ultimately increase the sustainability and liveability of cities.
