Window typology as a determinant of indoor air quality in naturally ventilated tropical African offices

), while projecting-window offices recorded the highest adjusted RH (70.56%). Although unadjusted findings suggested window-related differences in carbon dioxide, the final regression indicated that the number of windows (B = -9.24, p = 0.041), rather than typology, was the stronger predictor. Overall, the study demonstrates that window geometry is an important determinant of pollutant dilution and moisture control in naturally ventilated tropical office buildings, and that performance-based window selection represents a low-cost passive strategy capable of improving indoor environmental quality and supporting energy efficiency.
