THERMAL PERFORMANCE OF STONECOATED ROOFS WITH COMMON CEILINGS IN IBADAN, NIGERIA: A CASE STUDY OF TROPICAL BUILDINGS

High solar radiation infiltrating through the roofs and ceiling configuration has been attributed to being the major cause of interior discomfort.In order to control internal heat imbalance in the tropics, the synergistic combination of the roofing sheet and ceiling underlay were key factors.Therefore, to maintain a moderate internal ambient temperature suitable for human habitation, this field research was conducted to investigate the influence of StoneCoated Roofing Sheets (SCORS) configured against some common ceiling underlay at different angles of 30, 45, and 60, respectively, in Ibadan, Nigeria.The miniature building model was positioned north-south on the field, and daily temperatures were recorded for a period of 6 months at 30-minute intervals using a multichannel data logger.The results demonstrated that the temperature of the Sampled Ceiling Materials SCM and SCORS decreases with increasing configuration angle.The results demonstrated that the temperature of the Sampled Ceiling Materials SCM and SCORS decreases with increasing configuration angle.The average temperature at 30, 45, and 60, between 6 pm and 10 pm was 37.14-26.28,35.18-26.38,37.28-28.06,showing a downward trend in temperature as the sunset approaches.
