Determination of clay brick wall thickness for comfortable room temperature in Bida town

Abstract

The thickness of clay brick wall has been analysed for comfortable room temperature in Bida town of Niger State(latitude 9’8). This comfortable room temperature is without the need to use air conditioner. Conductive heat transfer analyses with and without heat source were made for unsteady state condition to obtain a suitable thickness. To validate the result, a prototype structure of clay was built without windows. Experiment was performed using this prototype by keeping it in the sun throughout the day. The variation of temperature both inside and outside the prototype structure were recorded. The theoretical results were then compared with experimental results and were found to be in agreement. A brick thickness of 224.5mm was found to be suitable for building application.
