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.

本数据集汇编了美国采用工程木（mass timber, MT）、结构钢（structural steel, SS）与钢筋混凝土（reinforced concrete, RC）建造的建筑的物料清单。所涉建筑分为IVA-18层、IVB-12层及IVC-8层三类，均按照《2021年国际建筑规范》（International Building Code 2021, IBC 2021）的要求进行设计。本研究采用雅典娜建筑影响评估计算器（Athena Impact Estimator for Buildings, IE4B），针对75年基准研究周期（reference study period, RSP；ASTM 2022; EN 2011）的环境影响评估生成物料清单，并开展建筑全生命周期评估（whole building life-cycle assessment, WBLCA）。此外，本数据集还生成了60年基准研究周期下的物料清单与建筑全生命周期评估结果，用于敏感性分析。鉴于即将发布的《2024年国际建筑规范》（International Building Code 2024, IBC 2024）中可能对耐火等级作出调整，本数据集额外补充了IVB-12层建筑的相关数据，用于开展敏感性分析以展示不同的建筑全生命周期评估结果。
