Green Roofs and living walls

Vertical greening systems are becoming an ever-increasing focus within contemporary architecture due to their ability to decrease run-off potential, atmospheric pollution, and building maintenance needs. This can also increase building insulation and indeed mitigate the effects of the urban heat island phenomenon, where buildings and pavements absorb and reflect heat. This is especially becoming a heightened problem due to urban population increase and climate change. Greening systems may also have ecological benefits alongside environmental benefits, as living walls and roofs hold the potential for ecological reconciliation, without affecting societal infrastructural utilization within the anthropogenic environment. These systems are still viewed as engineering projects, as opposed to ecological projects, but slowly the general census is changing, as people start to truly understand the value of biodiversity and it's incorporation in the urban infrastructure.

The main benefits to green roofs are as follows:

• Structural protection

• Energy conservation

• Temperature regulation

• Wildlife regeneration

• Water drainage and water attenuation
