Abstract : This study examines the distribution of knowledge and capacity gaps among architects on Green Building Design Strategies (GBDS) in Lagos, with a focus on how varying knowledge levels influence the integration of sustainable design principles in high-rise office projects. A quantitative survey of 344 architects and qualitative interviews with 12 experts were used to assess knowledge levels across major GBDS categories, including passive design, water efficiency, energy efficiency, sustainable materials, and technological systems. Descriptive statistics and Relative Importance Index (RII) were used to quantify knowledge patterns, while thematic analysis was employed to interpret qualitative insights. RII values ranged from 0.74 for sustainable materials and 0.73 for energy efficient lighting and passive cooling to 0.70 for smart building management systems, revealing significant variation in architects’ mastery of GBDS. Knowledge was found to be unevenly distributed, with architects demonstrating stronger familiarity with sustainable materials and passive strategies, while technological systems revealed clear capacity gaps. Analysis of firm type and years of experience further showed uneven knowledge profiles across private, corporate, academic, and government sectors. The study highlights the need for targeted capacity building initiatives to bridge identified knowledge gaps, particularly in technological GBDS. Improving professional training, strengthening green building curricula, and integrating sustainability focused Continuing Professional Development programmes can enhance architects’ readiness to implement advanced GBDS in Lagos. This research provides in-depth knowledge distribution assessments of Lagos based architects using a large empirical dataset.
