Abstract

Approximately 45% of the average household electricity in Malaysia is consumed by air conditioners to create an acceptable indoor environment. This high energy consumption is increase due to poor thermal performance of the building envelope. Therefore, selecting a low thermal conductivity of brick wall is of considerable important in creating low energy building consumption. Numerous studies have reported the potential use of agricultural waste as an additive in building materials to enhance their thermal insulation properties. The objective of this study is to examine the use of agricultural wastes from empty fruit bunch (EFB), coconut fibre (CF) and sugarcane bagasse (SB) as additive agents in a fired clay brick manufacturing process to produce a low thermal conductivity clay brick. In this study, these agricultural wastes are individually mixed with clay soil in different proportions ranging from 0%, 2.5%, 5%, 7.5% and 10% by weight. Physical and mechanical properties including soil physical properties, as well as thermal conductivity has been examine in accordance with BS 1377: Part 2: 1990, BS 3921: 1985 and ASTM C518. The results of this study reveal that incorporating 5% of EFB as an additive component into brick making process significantly enhance the production of a low thermal conductivity clay brick as compared to other waste alternatives tested. The control brick (CB) and 5% EFB masonry wall at size 1 m x 0.102 m x 1 m is built to access thermal surface temperature of the masonry wall model. The results reveal that the 5% EFB brick reduces the thermal conductivity value as well as reduces the thermal surface temperature of the constructed masonry wall model at night, where the significant on thermal imaging colour show much faster release heat. The outcome of this research suggests clearly that EFB waste is a potential additive material for thermal insulation enhancement of the building envelope. Thus, the temperature of the outer surface of the wall give impact inside building, where EFB waste bricks able to give thermal comfort inside building during at night.
