An Assessment of Comfort Levels of Buildings with Shaded and Non-Shaded Windows in Warm Humid Climates


Article Preview

Thermal comfort problems experienced in buildings in warm humid climates has been a major concern for designers in the environmental design specialty especially in Nigeria and other developing countries. This paper through controlled experiments studies the effect of window shading on indoor comfort levels of buildings exposed to warm humid climates. Experimental model buildings with shaded and non-shaded windows were constructed for this purpose. Comfort data were obtained from the buildings and meteorological stations including comfort parametric ranges. The data were analyzed with statistical tools involving the central tendency and dispersion. Hypotheses were tested. Results showed that window shading has significant effect on the comfort level of buildings and consequently energy usage.
