DOE’s Building Technologies Office hosted a series of webinars in fall 2020 that explored the frameworks and techniques researchers use to evaluate the energy use of buildings over their entire lifespans, from construction to operation to eventual destruction. The Life Cycle Energy and Related Impacts of Buildings Webinar Series gave the public, national lab researchers, academics, and all members of the buildings industry a special opportunity to hear from leading experts who work at the cutting-edge of lifecycle analysis. 

The series began with an overview of life cycle assessments as applied to buildings, and why we should care about them. Subsequent webinars will focus on the ways these impacts are measured, as well as what innovative materials and products are currently under development. The series will then explore how the buildings industry already uses life cycle assessments, as well as how the circular economy framework can be applied to the buildings sector.
