Abstract

This paper discusses on reducing indoor temperature vis-à-vis making indoor temperature comfortable for occupant by application of suitable cheap building materials such as the wall and the roof. The discussion is prompted by the daily rise in the cost of building materials at the expense of dwindling economic indices especially in developing nations. The survey was done in a typical rural environment in Abakaliki, Nigeria. Two types of prototype buildings were used for the study: mud block with thatched roof and mud block with corrugated roof.  The outside and inner temperature of the two buildings were taken at interval of 30 min for a period of 6 months. The average temperature in each case was evaluated. Our results indicates that the inner room temperature for the thatched roof was significantly lower than that of the corrugated roofs throughout the day. The difference between the maximum inner temperature for the thatched roof and the corrugated roof is 4oC, while the difference between the minimum is 6.0 oC.
