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.

本数据集汇聚了美国地区采用大宗木材（MT）、钢结构（SS）和钢筋混凝土（RC）构建的建筑物料清单。建筑类型包括IVA-18层、IVB-12层和IVC-8层，其设计均符合国际建筑规范2021年版（IBC 2021）。为了生成参考研究期（RSP）为75年（ASTM 2022；EN 2011）的环境影响评估物料清单，并执行整栋建筑的生命周期评估（WBLCA），使用了雅典影响估算器（Athena Impact Estimator for Buildings，简称IE4B）。此外，为进行敏感性分析，针对60年的RSP，也生成了物料清单和WBLCA。鉴于即将发布的国际建筑规范2024年版（IBC 2024）中关于防火等级的潜在变更之一，为IVB-12层建筑类别创建了额外的数据集，以进行敏感性分析，以展示不同的WBLCA结果。
