Research Kick-off: How Living Walls Can Tackle Urban Heat Islands

Green facades, also known as vertical gardens or living walls, are one of the promising solutions to the increasing problem of urban heat islands and air pollution in cities. Urban heat islands are a phenomenon where urban areas experience higher temperatures compared to their rural surroundings due to the concentration of heat-absorbing materials. This not only affects the comfort of city dwellers but also contributes to global warming.

Green facades provide a solution to this problem by absorbing heat and releasing oxygen, resulting in a cooling effect on the surrounding area. In addition, they act as natural air filters by absorbing pollutants and reducing the concentration of particulate matter in the air. Green facades can be made up of various types of plants, with each species offering different benefits. For example, certain plants have been found to absorb harmful chemicals such as formaldehyde and benzene, while others have a high transpiration rate, which helps to cool the surrounding air.

Research park for sustainable and healthy building material

Kicking off the Living Walls research in 2023

The VIVA research park in Wopfing will be yet again the place where products are tested, optimised and approved based on strict research criteria. In 2023 we are kicking off the research project and collect data to see the impact of green facades on the indoor comfort of one house and compare it against other research houses. Expected results in autumn 2024.

Green facades, or vertical gardens, can have a number of positive effects, including:

  • Improved air quality: Plants act as natural air purifiers by removing pollutants and producing oxygen.
    Increased property value: A well-maintained living wall can enhance the visual appeal of a property and increase its market value.
  • Energy savings: Plants provide shade and insulation, which can reduce the need for heating and cooling, leading to energy savings.
    Reduced noise levels: Living walls can act as sound barriers, reducing noise levels in the surrounding environment.
  • Improved mental health: Studies have shown that exposure to plants and greenery can have a positive impact on mental well-being, reducing stress levels and improving mood.
