A Bills of Materials Dataset for Buildings Made of Mass Timber, Structural Steel, and Reinforced Concrete Using the 2021 International Building Code Provisions

This dataset compiles a bill of material for buildings in the United States made of mass timber (MT), structural steel (SS), and reinforced concrete (RC). The buildings are classified as IVA-18-story, IVB-12-story, and IVC-8-story and are designed in compliance with the International Building Code 2021 (IBC 2021). The Athena Impact Estimator for Buildings (IE4B) was used to generate the bills of material for the Environmental Impact Assessments for the reference study period (RSP) of 75 years (ASTM 2022; EN 2011) and to conduct the whole building life-cycle assessment (WBLCA). Additionally, bills of material and WBLCA for the RSP of 60 years were generated for sensitivity analysis. Due to one of the potential changes in the fire rating in the upcoming International Building Code 2024 (IBC 2024), an additional dataset for the buildings in the category IVB-12-story was created to perform sensitivity analysis to show the different WBLCA results.
