POST-OCCUPANCY EVALUATION OF GREEN-CERTIFIED BUILDINGS IN LAGOS: LINKING USER CHARACTERISTICS TO PLACE PERFORMANCE OUTCOMES.

This study evaluates the relationship between users’ socioeconomic characteristics and place performance outcomes in green-certified buildings in Lagos State, Nigeria. A quantitative post-occupancy evaluation approach was adopted using structured questionnaires administered across nine LEED and EDGE-certified buildings. Out of 1,119 distributed questionnaires, 1,004 valid responses were retrieved and analyzed using descriptive statistics, Building Condition Index (BCI), Place Performance Index (PPI), Pearson correlation, Chi-square analysis, and Analysis of Variance (ANOVA). The findings reveal that the assessed buildings generally exhibited high technical and environmental performance, particularly in indoor comfort, energy efficiency, ventilation, and maintenance quality. Perception and green housing among green-certified buildings were significantly influenced by socioeconomic variables such as income, occupation, age, education, and household size while gender showed no significant relationship. The calculated BCI values ranged between 3.68 and 4.40, however, PPI values ranged between 4.00 and 4.53, which is an indication of a general high place performance across the assessed buildings. Furthermore, the findings establishes that a strong positive relationship exists between building condition and place performance and also demonstrates that user satisfaction and environmental functionality extend beyond technical efficiency alone. The study concludes that effectiveness of green building performance in Lagos is dependent on the interaction between the physical building quality, socioeconomic actualities, and user experience, thereby stressing the need for context-responsive sustainability frameworks in Nigeria.
