Urban greening activities are underpinned by diverse organisational arrangements. Frameworks have been developed to articulate how such arrangements support the understanding and development of urban greening governance and practice. This paper builds on these frameworks with an additional consideration - levels of formality and informality.

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.

Covering roofs and walls of buildings with vegetation is a good way of reducing greenhouse gas emissions. And these green roofs and walls make cities look nicer. Toronto’s central business district adopted a policy of establishing green roofs on around half of all city buildings in 2009. Research shows this could reduce maximum city temperatures...

This report provides an in-depth analysis of the costs and benefits of applying a set of smart surface solutions1 , including cool roofs, green roofs, solar PV, and permeable and reflective pavements and road surfaces across three cities: El Paso, Philadelphia and Washington, D.C. The report demonstrates that cities can strengthen resilience, improve health and...

Problem: Roofs receive the most intense solar heat load among all building envelope surfaces in Equatorial-region. Solar heat gain through roof contributes to a significant portion of building heat load. In tropics where building cooling is needed all-year-round, passive methods to reduce heat gain through roof could provide significant cooling energy-savings. Approach: Currently, the most...
