Research on Eco-Friendly Architectural Design Applications in High-Rise Office Buildings - Focusing on Void-Type Architecture -

Abstract

This study explores the potential of eco-friendly void spaces in high-rise office buildings to enhance energyperformance and occupant comfort, with the goal of proposing a prototype adaptable to domestic urban conditions. Drawing from Ken Yeang’s green skyscraper theory, this research reinterprets the functional and environmental rolesof voids through theoretical examina-tion and case-based analysis. A comparative study of domestic and internationalexamples reveals that global practices tend to integrate voids within complex structural and environmental systems,thereby maximizing energy efficiency. In contrast, domestic applications are more limited in scope and technical depth;however, the incorporation of green elements such as green walls indicates significant potential for environmentalresponsiveness and passive energy control. The findings suggest that when combined with localized climate strategies,eco-friendly voids can serve as key design elements for achieving sustainability in high-rise architecture. Simulationresults show that the proposed prototype reduces annual energy consumption by approximately 20–25%, demonstratingmeasurable performance benefits. This research offers a foundational perspective for the future implemen-tation ofperformance-driven, environmentally responsive design in the vertical built environment.1
