Evaluating the Impact of Biocomposite Brick Materials on The OTTV and Diverse Thermal Characteristics of Rooms in Residential Buildings

Abstract

The development of biocomposite materials for building purposes, including their incorporation in bricks, has gained momentum. Bricks are extensively utilized in residential buildings in Indonesia, making their performance a critical factor. To ensure building performance meets certain standards, Indonesia adheres to SNI 6389:2011, which mandates compliance with the Overall Thermal Transfer Value (OTTV) before construction commences. This study aims to examine the impact of using biocomposite bricks on the OTTV value. Additionally, it investigates the effects on various thermal properties of the room, such as humidity, air temperature, operative temperature, and Mean Radiant Temperature (MRT), which serve as indicators for assessing thermal comfort. The findings demonstrate that the use of biocomposite bricks can reduce the OTTV value by approximately 7.9% - 10.2%. However, there is no significant alteration observed in the physical properties of the room when compared to conventional bricks. As a result, it can be inferred that the use of biocomposite bricks holds promise for further progress in enhancing energy efficiency and addressing environmental concerns.
