A Blockchain-based Life Cycle Assessment (LCA) Framework for Building Materials Selection

Real estate companies wishing to deploy blockchain-based solutions are faced with a plethora of competing technologies, each with a large number of unique parameters that must be adjusted by an expert. In this article, we propose A blockchain-based Life Cycle Assessment (LCA) framework to guide the choice of construction materials. LCA is a multi-criteria evaluation method based on ISO 14040 and 14044 standards and which can be based on additional standards depending on the sector studied and the objectives of the study. It aims to produce an assessment of the potential environmental impacts of a product or activity. It is characterized by a holistic approach to the problem, considering the entire life cycle of the product(s) studied. We build a knowledge base of blockchain solutions and run an automated multi-criteria decision process giving the most relevant solution based on requirements and preferences. We validate our approach on a building material case study.
