Façade Greening for Healthy Urban Air: An Umbrella Review on Particulate Matter Reduction, Challenges, and Future Directions

The fundamental research involved the preparation of an Umbrella Review, which highlights the current state of the art in relation to particulate matter and façade greening. The paper covers the following areas: Measurement techniques and analytical methods for determining particulate matter accumulation on plants, external influencing factors, the effectiveness of façade greening, leaf traits that are beneficial and plant species.

The paper entitled "Façade Greening for Healthy Urban Air: An Umbrella Review on Particulate Matter Reduction, Challenges, and Future Directions" was published on January 4, 2023 in the journal MDPI, Sustainability, Basel.  https://www.mdpi.com/2071-1050/16/1/446 The key findings show that different methods, plant species and different environmental conditions lead to different conclusions.

The article addresses knowledge gaps in both research and practice, and its findings can already be applied in subsequent research efforts and in the implementation of façade greening projects.
