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.
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). In particular, the presence of green walls and facades within city precincts has grown tremendously in the recent decades since inception of the concept in the seventeenth and eighteen centuries. Initially designed as aesthetic features, their (additional) merits in terms of easing the urban island heat effect and improving the adjacent building energy efficiency are turning them into highly valued urban assets.

Industry misconceptions around high cost and poor market interest in energy efficient homes continue to obstruct the mass adoption of low carbon housing. Josh’s House demonstrates that low carbon housing is accessible and cost effective. The Star Performers series showcases how...Read more
Research on the energy efficiency of the different components of buildings – their shell, built-in appliances, plug-in appliances, floor size and floor plan, as well as position on site – all have contributions to make to amount of energy consumed. When combined with renewable...Read more
Pilots are powerful for two reasons: 1. They are a great way to bring together groups of people to demonstrate how effective collective action can be in helping to change the status quo. More voices, more influence. Pilots, backed by evidence and research, can highlight and expose the challenges and blockages, particularly in government, far more effectively than any individual can (despite many individuals trying!). They also provide perfect opportunities for identifying solutions. And, 2. pilots provide the numbers and the evidence that decision-makers need, in order to believe and make change.Read more
The traditional use of water in our cities severely distorts the natural water cycle, consuming potable water for purposes such as toilet flushing and irrigation, whilst discharging excessive volumes of stormwater runoff and wastewater.
Josh’s House is an exemplar of integrated water sensitive urban design at the residential housing scale.
Josh’s House is an innovative housing-scale sustainable design and construction project based in Hilton WA, led by environmental scientist and national media personality Dr Josh Byrne in conjunction with Curtin University and the CRC for Low Carbon Living.
