Abstract
Energy consumption data reveals that buildings account for 40 % of overall energy usage. Without urgent intervention, this figure is poised to escalate alongside population growth, exacerbating the dependence on fossil fuels for energy production. Addressing this pressing issue demands effective measures to curtail energy consumption in buildings, a realm where research on bamboo's thermal performance still needs to be improved. This study fills a critical gap by investigating the integration of bamboo fibre in the briquettes, known for their high heat transfer coefficient (U-value). Leveraging the innovative coheating test method, the research pioneers an unexplored avenue to evaluate thermal performance. This novel approach distinguishes the study as a unique and original endeavour in the field. The findings demonstrate significant thermal enhancements by substituting bamboo fibre: 2 %, 4 %, and 6 % bamboo additions yield U-values of 4.698 W/m2K, 3.94 W/m2K, and 2.77 W/m2K, respectively. Notably, the 6 % bamboo-reinforced briquette showcases a remarkable 49.9 % improvement in thermal resistance compared to conventional counterparts. This study marks a pioneering effort towards achieving energy efficiency through sustainable materials in designing low/zero carbon buildings. By showcasing the potential of bamboo as a thermal insulator, the research illuminates a promising path for future construction practices. Embracing such innovations is paramount in mitigating the environmental impact and securing a sustainable future.
