There are many factors that must be considered before evaluating claims that one or another building type or product offers a better environmental return. To understand the full environmental impact of a structure over decades of use, all phases, starting before construction and continuing through demolition, must be considered. Life cycle assessment (LCA) seeks to quantify the environmental impacts over the infrastructure life cycle by identifying the costs during each phase.
LCA can be used to obtain credits in certification systems like LEED, but traditional LCA methods can be time, resource, and data-intensive. For complex systems like residential buildings, these demands can lead to delayed assessments with evaluations carried out after important design decisions have already been made, reducing their effectiveness. CSHub researchers have developed a streamlined approach to LCA that requires significantly less time and data, which can reduce expense as well as uncertainty and allow assessments to be conducted earlier in the building design process when decisions can have the greatest impact.
