Comparative Study of Thermal Performance of Building Wall Materials in Bauchi State Nigeria

This study focus on the performance of selected secondary school building walls in the hot and dry tropical Climate of Bauchi, Bauchi state Nigeria. The objective of present study was to explore the most efficient way to retrofit existing public schools in Bauchi as the state government embarks on extensive renovation work of the existing school building to provide a more conducive environment for the student’s academic activities. Six different wall configurations including the existing wall were simulated during hot season using Design Builder simulation tool to evaluate the wall impacts on the classroom air temperature and relative humidity (RH). The simulation results analysis shows that although the wall configuration with wall insulation produce a lower indoor air temperature, yet it may not be sufficient to provide the needed and thermal comfort. Therefore, to achieve appropriate level of thermal comfort in Bauchi public schools, emphasis should be on both the walls and the roof. This study shows that improving only the wall thermal performance may be an insufficient strategy.
