Tabriz, the capital of East Azerbaijan Province in north-western Iran. This study addresses that gap by developing and validating a structured indicator model for climate-adaptive, energy-optimised high-rise building design in Tabriz, using the Fuzzy Delphi Method (FDM) applied across four iterative rounds to a panel of fifteen domain experts in architecture, building physics, and environmental engineering. Beginning from twenty-one candidate indicators drawn from five conceptual domains opaque envelope thermal performance, transparent envelope and solar management, building form and orientation, active mechanical systems, and contextual passive strategies the iterative consensus process reduced the set to thirteen validated indicators, with Kendall’s coefficient of concordance (W) stabilising at 0.786 in the final round, confirming statistically significant and stable expert agreement. The four highest-priority indicators identified were wall thermal insulation compliance (mean 4.28), external shading device effectiveness (4.25), mechanical HVAC system efficiency (4.22), and glazing thermal performance (4.22), reflecting the dual-season energy imperative of Tabriz’s climate. The resulting thirteen-indicator model provides a coherent, empirically grounded, and operationally actionable framework for guiding the design of new high-rise buildings, the energy-based assessment of the existing stock, and the development of Tabriz-specific regulatory performance thresholds for tall building construction. https://www.ijumes.com/article_736088_28b0804d4afe477fd906164c0795a197.pdf
