This article presents and describes a dataset for the bills of materials for the buildings constructed with mass timber (MT), structural steel (SS), and reinforced concrete (RC), which are generated using Athena's Impact Estimator for Buildings (IE4B) software to conduct a whole building life-cycle assessment (WBLCA). These data are associated with the research article Environmental Impact Assessment of Mass Timber, Structural Steel, and Reinforced Concrete Buildings Based on the 2021 International Building Code Provisions [1]. This dataset was utilized to estimate their environmental impacts but can be used to estimate the costs of buildings constructed with MT, SS, and RC building materials. These data could be replicated using the same layout, system boundaries, reference study period (RSP), and building assemblies’ information as used in the published work [1]. This dataset is related to conceptual design of a building with 11 apartment units per floor. However, a detailed design that includes the analysis of interior architectural finishes such as internal partitions within the units, kitchen and washroom fixtures, internal doors, flooring, and so on, could be developed and analyzed to obtain a more comprehensive estimates of life cycle assessment. This dataset was originally developed to compare the environmental impacts of structural materials selection for three common framing typologies.
