Sustainability of buildings is an essential topic – buildings and construction consume almost half of raw materials and one third of energy in Europe. Therefore, scaling up the building sustainability assessments and making them faster and more reliable is a key challenge.

Building sustainability is evaluated with a Life Cycle Assessment (LCA). An LCA is a quantitative method of assessing a building’s environmental impact throughout its life cycle, i.e., procurement, construction, operation, and decommissioning. The assessment allows owners to optimize the entire building process from a life cycle cost perspective instead of resorting to short-term sub-optimization.
