Green walls – why bother?

Green walls – why bother?

Our ‘Green Building‘ page has a summary of the benefits of green roofs. But what of green walls? Why kinds are there, and what do they do?

These days there’s a fashion for green walls that involve technical, modular systems which support pocket planting of a huge array of vegetation. Your local supermarket may have one, or you might spot an internal ‘living wall’ in a boutique in town. There’s no doubt these living wall systems can be stunning – with great examples at Westfields in Shepherd’s Bush, and on The Rubens at The Palace in Victoria, London.

However, simple is good too, and simple green walls using trailing or climbing plants have been around for millenia. Taken in the round, and considering the energy it takes to create and eventually dispose of a green wall, and the benefits during its life, these simple green walls perform best.

Benefits include:

  • Prolonging building fabric
  • Trapping pollutants which accelerate decay
  • Biodiversity
  • Visual amenity
  • Property value
  • Cooling

If you’ve got some spare time, take a look at this talk on Green Walls by James Farrell of Brighton & Hove Building Green and Lee Evans of Organic Roofs Ltd. at Green Architecture Day 2017.

Lee goes on to talk about living roofs, so it’s a twofer.

We have a historic example right here in Brighton & Hove. The green wall at Madeira Drive is the oldest and longest in the country, and was planted in 1872. It now supports over 100 species of wild plant and a range of other wildlife.

What about your house, block of flats, or workplace? Yes, they can have a green wall too. The book ‘Building Green’ contains tips on how to do it, and a handy planting guide to help you select the right plants for your local environment and the benefits you are seeking.

Do Green Roofs Provide Storm Water Attenuation?

Green Roof“The benefits of green roofs are well documented and established, but uncertainty remains as to whether they can provide attenuation and storage for storm water.

“Micro Drainage worked with the University of Sheffield to establish a model to accurately factor the runoff from a green roof.

“The outcome now enables a green roof to be modelled as part of a Sustainable Drainage System (SUDS).”
