Sustainable Resources to Improve on Living Green Walls Acoustics: Supply Chain Study
* Presenting author
Living Green Walls (LGWs) or Vertical Gardens are built and deigned using a selection of plants, growing medium, frames, supports, and irrigation system. LGWs are considered as a natural solution of controlling noise especially in urban environments. A better sound absorption can be achieved through replacing the currently used growing medium by a new material with a higher porosity. A high porosity material allows more sound to enter and dissipate in the material matrix. Coconut fibre can be a considerable alternative for the currently used growing medium, due to its high porosity. It has proven that natural fibres have good sound absorption coefficient at medium and high frequencies (500-2000HZ). The study works on improving the LGWs acoustic using sustainable resource (Coconut fibre). In order to increase the sound absorption over the current LGWs and utilise the coconut waste obtained from grinding the coconut waste which naturally exists. Moreover discussing the impact of introducing the coconut to the LGWs Supply Chain. The paper presents analysis based on real data collected from LGWs companies.
