Performance-Driven Evaluation and Parametrical Design Approach for Sustainable Complex-Tall Building Design at Conceptual Stage

Tall buildings with irregular forms are gaining popularity in creating the vertical city model, and they are designed and built today with the help of computational technologies. This paper aims to highlight the significant link between the architectural and structural conceptual design of tall buildings with irregular geometries by using performance-driven evaluation and parametric design approach at conceptual stage to develop a sustainable design. Initially the review of previous research shows how the form of tall building is be defined. Furthermore, the parametric design approach is investigated for generating alternative options to satisfy building aesthetic and structural performance criteria with the aid of aerodynamic optimization technicque to generate an optimum solution for decision-making at an early stage, as well as allowing modifications in the later stages of design, and making it possible to handle the design process in a repetitive manner. Finally, a framework is proposed where computational techniques are integrated and an effective collaboration between professional designers is achieved in order to produce an optimal complex-tall building conceptual design that is architecturally pleasing, structurally efficient, and environmentally sustainable.
