The methodology that is used to evaluate and study the economic performance of a building or system over its entire life is life cycle assessment (LCA). LCA is a technique that assesses the environmental aspects and potential impacts associated with a product, process, or service throughout its life cycle, from raw material extraction to end-of-life disposal or recycling7. LCA can also include an economic dimension by incorporating life cycle costing (LCC), whichestimates the total costs of ownership over the life cycle of a product or system8. By combining LCA and LCC, one can evaluate the environmental and economic performance of a building or system in a holistic way, taking into account both the initial investment costs and the long-term operational costs. This can help identify trade-offs and synergies between environmental and economic objectives, as well as opportunities for improving efficiency and reducing impacts9. References: Life-cycle assessment7; What is Life Cycle Assessment (LCA)?8; Life Cycle Costing in Construction Projects: A Case Study of a Municipal Building in Portugal9
