Abstract

The paper presents indoor conditions for human thermal comfort in Nigeria. Ilorin (Lat.8°26’’23’’Long.4°29’41’’) is used as a case study. Four (4) different activities concerning effective management and optimal utilization of workers in Nigeria were given priority in the research work. The model equation developed by Fanger [1] was used in the study. The equation takes cognizance of heat balance of the body with the environment, skin temperature and perspiration heat loss. The variables affecting thermal human comfort were studied and experiments conducted to determine the micro climatic conditions under which people in the area feel comfortable. Experimental results and heat balance equation developed by Fanger [1] were coupled to determine the heat loss due to regulatory sweating in the zone. The results show a need for air conditioning system with a variable thermostat to enhance the attainment of thermal comfort conditions for a given activity. The results also show an inverse relationship between activity levels, skin temperature and ambient temperature of the enclosed space. These results could be extended to other parts of the country since the experiments were carried out in an enclosed space.
