Life cycle assessment of felt system living green wall: Cradle to grave case study

Abstract

Life Cycle Assessment (LCA) is a commonly used approach for assessing the environmental impact of products, processes, or services. This paper presents LCA of a selected Living Green Wall (LGW), a greening structure which is attached to building envelope and improve its sustainability. Impacts of the LGW useful life stages (manufacturing, construction, maintenance, and disposal) are quantified through LCA. In this study a felt system LGW example was selected, to build a case study. The information on the component's material, weight, supplier, distance travelled, and type of transportation (inventory data) was gathered from the manufacturer. The data gathering process was through informal interview and manufacturer's public information search. The study found that the manufacturing stage of LGW production is responsible for 80.67 % of the Greenhouse Gases emissions (GHG).
