Evaluating the Cost, Carbon and Energy Impacts of Different Structural Systems

When choosing a structural system, questions related to cost, carbon accounting and energy efficiency are often at the forefront. This presentation will highlight two recent projects where these topics were studied in depth. KL&A Engineers and Builders will present the results of an LCA study comparing the embodied carbon, construction costs and speed of construction of three functionally equivalent buildings in mass timber, steel and concrete. They’ll review the methodology, assumptions, analysis and results to better understand the impact of each system on embodied carbon and economy for a given project. Architecture firm LHB will also present a case study of the first affordable, multi-family passive housing project in Minnesota. Topics will include the design’s evolution, building enclosure details, acoustical challenges, how the team achieved simple yet effective and buildable solutions, and more.
