The transition to ecologically integrated vertical housing is pivotal to the sustainable development vision of Indonesia’s new capital, Ibu Kota Nusantara (IKN). This study identifies and prioritizes the critical success variables influencing the implementation of green building initiatives within IKN’s vertical housing projects. By employing the MICMAC (Matrice d’Impacts Croisés Multiplication Appliquée à un Classement), a structural analysis approach, the study evaluated inter-variable influences across five sustainability dimensions: environmental, social, economic, institutional, and infrastructural. A total of 91 expert respondents were selected through purposive sampling to assess the strength and dependence of 30 operational variables. The analysis reveals a clear hierarchy, identifying 11 determinant (driver) variables and 9 key (relay) variables as most critical to the system’s success. Among the most influential drivers are policy synergy and fund allocation efficiency, which serve as foundational enablers. Meanwhile, community involvement and effective waste management were identified as highly sensitive relay variables that connect strategic policies to tangible outcomes. The research highlights that sustainable high-rise development in IKN requires not only green technology and regulation, but also multidimensional coordination, ecological sensitivity, and inclusive design strategies. The findings offer a practical framework for guiding decision-makers, planners, and developers in achieving ecologically resilient urbanization in tropical environments. © 2025 by the author(s).
