Abstract : The continuous environmental impact of high-rise office construction in Lagos requires architects to adopt Green Building Design Strategies (GBDS). This study examines how architects' knowledge influences GBDS adoption using a mixed-methods approach, drawing on data from 344 architects and 12 expert interviews in Lagos. Analytical methods are descriptive statistics, the Relative Importance Index (RII), chi-square tests, correlation analysis, and Principal Component Analysis (PCA). Architects' knowledge was highest for sustainable materials (RII = 0.74), energy-efficient lighting (RII = 0.73), and passive cooling/ventilation (RII = 0.73), and lowest for smart building management systems (RII = 0.70). Adoption showed a similar pattern: sustainable materials ranked highest (92.73%), while advanced technological systems ranked lower. Chi-square analysis confirmed knowledge significantly impacted adoption (χ2 = 358.703, p < 0.001), while limited knowledge predicted low adoption (χ2 = 247.308, p < 0.001). There is a strong positive correlation (r = 0.71) between knowledge and adoption. PCA identified three components: passive/environmental control strategies, resource/waste management, and technological/renewable energy systems. The study concludes that knowledge is the main driver of GBDS adoption among Lagos architects, though its impact is moderated by cost, technology exposure, institutional support, and curriculum review.
