High-rise building construction requires substantial use of structural materials, leading to a significant environmental impact characterized by excessive emissions during the product stage. With improvements in operational energy performance, embodied carbon (EC) emissions during product and construction stages of a building become increasingly significant. To reduce EC emissions, early structural design decisions play a pivotal role for high-rise building construction. Although recent studies have explored EC emissions in building life cycle assessment (LCA), a comprehensive framework specifically targeting tall building structures remains unaddressed. This research introduces a systematic approach for EC estimation in structural systems of tall buildings during early design phase. A total of 103 parametric analytical models and 192 scenarios are generated through an automated structural analysis and design process for various load scenarios, comprising a combination of three different load cases for both wind and earthquake loads. The process is implemented iteratively to satisfy predefined structural performance requirements and is executed in Python via the ETABS API. The systematically defined design parameters and corresponding EC emissions of the generated analytical models are compiled into a database to facilitate the development of EC reduction strategies. By providing a robust empirical dataset, this study establishes the necessary infrastructure for future predictive tool development. The findings of this research can guide designers in estimating and mitigating EC emissions at the early design stage of tall buildings. In this regard, this study advances sustainable structural design practices, thereby contributing to broader sustainable development goals within the built environment.
