Life-cycle assessment, or LCA, is the science of quantifying environmental impacts through the entire process of creating, transporting, using, and disposing of a product or material. Environmental impacts assessed include things like embodied carbon, smog-creation potential, and fossil fuel consumption.  

For building professionals, LCA comes into play in two main ways. To understand the impacts of specific products, look to an environmental product declaration (EPD). To understand the impacts of an entire building, a whole-building LCA is required. Specialized tools are used to perform whole-building LCA.

  • Whole-Building Life Cycle Assessment: Promises and Pitfalls

    Webcast

    Whole-building life-cycle assessment (WBLCA) promises improved performance with reduced environmental impacts. Yet in practice it can bog projects down with confusing or even conflicting priorities, complicated by mountains of data.

    BuildingGreen has arranged for four widely respected practitioners to share their LCA expertise, taking you from big-picture questions—Why should I worry about embodied impacts?—to practical details—How can I get good data on my building's concrete mix?
