Life Cycle Assessment (LCA) is a method that building practitioners can use to analyze the environmental performance of a proposed building design. However, surveys of building practitioners have shown that LCA tools are not widely used because the analyses are time-consuming, require burdensome data collection, and are poorly integrated with the design process. This brief discusses a CSHub-developed streamlined LCA methodology called the Building Attribute to Impact Algorithm (BAIA) which allows practitioners to focus on the parameters that matter and leave the rest underspecified. This speeds up the analysis process and leads to more informed design decisions. MORE.
