Abstract: Energy conservation refers to efforts made to reduce energy consumption. Energy conservation can be achieved through using efficient energy sources, in conjunction with decreased energy consumption or reduced consumption from conventional energy sources. A considerable energy saving can be achieved by using proper thickness of insulation in building walls. This paper briefly discussed mud wall as a better option of energy conservation over conventional brick wall construction buildings. After calculating the Energy saving value for a representative room of size 5 m x 4 m x 3.5 m, it is found that there is potential of energy conservation up to 520 kWh/Year by using mud wall instead of conventional brick wall.

Keywords: Energy conservation, mud wall, optimum insulation, conductive heat transfer.
