In the face of rising global temperatures and persistent energy deficits in Sub-Saharan Africa, sustainable architectural design has become increasingly essential. This study examines the prevalent passive cooling strategies employed by architects in contemporary building designs in Nigeria, with a focus on Lagos State as a case study. A quantitative research approach was employed, utilising a structured questionnaire distributed to 140 registered architects under the Architects Registration Council of Nigeria (ARCON), resulting in 106 valid responses. The data was analysed using descriptive statistics via SPSS. Findings indicate that the most widely adopted passive cooling principles include the use of insulating materials, sustainable construction materials, building orientation, and building form. In contrast, techniques such as roof gardens, courtyards, and atriums received lower ratings for application. These results underscore a trend among Nigerian architects toward material- and form-based cooling interventions as opposed to spatial or vegetative solutions. The study contributes to the growing body of literature on climate-responsive design, providing practical guidance for architects seeking to enhance thermal comfort while reducing energy demand in tropical environments. The findings also establish a benchmark for future research and design practices aiming to implement passive cooling in both residential and commercial projects across Nigeria.
