Carbon Accounting Tools for Structural Systems

Comprehensive overview of whole building life cycle assessment (WBLCA) tools and carbon calculators available to building designers for evaluating carbon impacts of different structural systems. Covers LCA methodology, detailed comparison of major North American tools (Athena Impact Estimator, tallyLCA, One Click LCA), differences in biogenic carbon treatment, simplified carbon calculators, and guidance for tool selection. Includes comparison table of tool features and limitations, software resource links, and emphasizes importance of understanding tool limitations and assumptions, particularly for wood buildings where biogenic carbon accounting varies significantly between tools.
