World Green Roof Day 2021

On 6th June 2021, World Green Roof Day is taking place to celebrate green roofs all over the world and the many benefits they bring to people and the environment, and to also get cities and towns all over the world to think about how they can deliver green roofs within their area.

Bauder is hugely proud to apart of the green roof industry because of the positive impact they have on the environment and climate change. Green roofs help maintain a buildings temperature by regulating temperature variability, insulating it from cold weather in the winter and absorbing the heat in summer. This reduces central heating and air-conditioning costs.

To highlight Green Roof Organisation (GRO) becoming the Trade Association for the green roof industry, they have launched an updated version of the GRO Code. After 7 years, the new GRO Code looks to develop the guidance for the specification and building of green roofs.
 
It gives greater detail on:

🟢 Vegetation
🟢 Drainage boards
🟢 Substrate make-up
🟢 Additional information on Fire Performance and Biodiversity Net Gain.

Green roofs have many benefits including:

  • Creates a natural habitat for flora and fauna
  • Aids biodiversity encouraging a wider spread of species in the area
  • Soft landscaping helps to reduce the risk of flooding by retaining large proportions of annual rainfall and reducing rainwater run-off. Particularly useful within Sustainable Urban Drainage (SUDs) schemes
  • Environmental masking blends the building into its surroundings
  • Improved air quality as vegetation assists in reducing both gaseous pollutants and dust particles
  • Reduces urban heat island effect (the difference in temperature between urban areas and the surrounding countryside) through absorption of some of this heat and the natural evaporation of water from plants and soil
  • Reduces building’s carbon footprint through lowering building running costs
  • Reduced construction costs: no requirement for screed on the deck reducing the overall weight imposed, fewer rainwater outlets, decreased rainwater drainage system capacity and a reduced requirement for storm water attenuation within the SUDs scheme for the site
  • Increased life expectancy of waterproofing membranes when protected by green roof landscaping
  • Many local authorities favour planning proposals that incorporate green roofs within the application, particularly if it meets their policies towards providing a sustainable environment
  • Increased property value – roof usage can be maximised for purposes including leisure, and offers unique potential for replacing the land lost to the building’s footprint
  • Noise reduction for the building – green roofs have excellent acoustic qualities for both external sound (up to 3dB) and internal noise up to 8dB)
 
Over the next week, Bauder will be posting green roof projects that we have been lucky enough to be apart of over the years all over our social media channels in order to celebrate World Green Roof Day. To take a look, visit our LinkedIn and Twitter profiles.
