Abstract

The integration of sustainable principles into digital fabrication has catalyzed the evolution of green buildings, with 3D printing emerging as a transformative tool for architectural innovation. This paper presents a comprehensive review of a multi-scale design model tailored for the additive manufacturing of structural and decorative façade elements in green buildings. The proposed model addresses the need for holistic design strategies that align material efficiency, energy performance, and aesthetic flexibility with green construction mandates. Anchored in computational design and parametric modeling, the framework enables multi-level optimization from microstructural geometries to macro-scale form articulation ensuring seamless integration with passive solar design, thermal insulation, and natural ventilation strategies. The review traces the progression of digitally fabricated façades from conceptual prototypes to functional building envelopes, emphasizing sustainable material selection, structural performance, and environmental responsiveness. Key developments in printable bio-based composites, fiber-reinforced polymers, and low-carbon cementitious blends are critically assessed for their compatibility with complex geometric configurations and their alignment with LEED and BREEAM green certification criteria. The model incorporates Building Information Modeling (BIM) and simulation tools to facilitate real-time assessment of thermal bridging, daylighting potential, and embodied energy across design iterations. Case studies of pioneering projects in Europe, Asia, and North America are analyzed to illustrate practical applications of multi-scale design thinking in additive manufacturing of façades. The paper also examines regulatory challenges, lifecycle assessments, and opportunities for digital mass customization in retrofitting existing structures with energy-efficient printed façades. By synthesizing advances in computational design, sustainability frameworks, and materials science, this work contributes a scalable design-to-fabrication methodology aimed at accelerating the adoption of 3D-printed façades in the green building sector. The findings underscore the potential of additive manufacturing to not only redefine architectural aesthetics but also to support the environmental goals of the built environment through resource-efficient, performance-driven solutions. This timely review responds to the growing demand for integrative and sustainable approaches in architectural 3D printing, establishing a foundation for future research and application in climate-responsive building envelope design.
