Quantifying the New European Bauhaus Principles Integrating Sustainability, Inclusiveness, and Aesthetics of the Built Environment

In September 2021, the European Union launched the New European Bauhaus (NEB) initiative to promote a green, inclusive, and aesthetically oriented transition across Europe. Although the NEB emphasizes sustainability, inclusiveness, and aesthetics, existing assessment frameworks rarely integrate these dimensions in a cohesive or adaptable manner. The objective of this research is to establish a flexible component-based framework capable of quantitatively capturing the core concepts of the NEB. The framework is developed through an extensive literature review and organized into a hierarchical structure that aggregates fine-grained performance metrics into dimension indices and a final composite performance index. A fuzzy Technique for Order Preference by Similarity to Ideal Solution (TOPSIS)–based weighting mechanism is incorporated to enhance adaptability and to better reflect the inclusive and participatory ethos of the NEB. The framework’s applicability is demonstrated through its use on the Mjøstårnet timber tower in Norway. Following an initial performance evaluation, the tower is redesigned using adaptive control principles and reassessed to demonstrate the framework’s responsiveness to design modifications and its capacity to capture multidimensional performance. The results indicate that the proposed framework can function as a robust and versatile tool to support policymaking, design innovation, and performance evaluation aligned with the evolving priorities of European construction.
