Wall case - Argex, Belgium

This study explores the life cycle assessment (LCA) methodology applied to the Argex wall case in Belgium. It highlights the importance of understanding future market demands while analyzing the environmental impacts of raw materials production, construction, and end-of-life stages of the wall. By defining a functional unit based on specific performance parameters like insulation properties, we can assess energy consumption, global warming potential, and other environmental factors over a 50-year lifespan. This assessment helps improve product design and process efficiency.

  1. Wall case - Argex, Belgium

  2. Purpose • To be prepared for future market demands. • Learn more about LCA and LCA methodology. • Learn about own products and own processes. • Where is the environmental impact greatest?

  3. Function The function of the product is important for defining the functional unit. The wall has defining parameters, such as heat and sound insulating properties. These should be included where they affect the performance and type and quantity of materials used. All utilities affecting the dimensions should be included in the functional unit, as far as possible. The functional unit for this case is: 1 square meter of house wall (1,00x1,00x 0,31 m) constructed, maintained and demolished after 50 years.
