Rapid urbanization has negative effects on ecology, economics, and public health, primarily due to unchecked population growth. Sustainable building materials and methods are needed to mitigate these issues and reduce energy use, waste production, and environmental damage. This study highlights the potential of agricultural waste as a sustainable source of construction materials and provides valuable insights into the performance and benefits of using fired clay bricks made from pomegranate peel waste. In this study, fired clay bricks were produced using pomegranate peel waste as a sustainable building material. To optimize the firing temperature and percentage of pomegranate peel waste, a series of experiments was conducted to determine fundamental properties such as mechanical, physical, and thermal properties. Subsequently, the obtained thermal properties were utilized as input data in Design Builder software version (V.5.0.0.105) to assess the thermal and energy performance of the produced bricks. The results showed that the optimum firing temperature for the bricks was 900 °C with 10% pomegranate peel waste. The fabricated bricks reduced energy consumption by 6.97%, 8.54%, and 13.89% at firing temperatures of 700 °C, 800 °C, and 900 °C, respectively, due to their decreased thermal conductivity. CO emissions also decreased by 4.85%, 6.07%, and 12% at the same firing temperatures. The payback time for the bricks was found to be 0.65 years at a firing temperature of 900 °C. These findings demonstrate the potential of fired clay bricks made from pomegranate peel waste as a promising construction material that limits heat gain, preserves energy, reduces CO emissions, and provides a fast return on investment.
快速城市化对生态、经济和公众健康产生负面影响，主要原因是人口增长失控。需要可持续的建筑材料和方法来缓解这些问题，并减少能源使用、废物产生和环境破坏。本研究强调了农业废弃物作为可持续建筑材料来源的潜力，并提供了关于使用石榴皮废弃物制成的烧制粘土砖的性能和益处的宝贵见解。在本研究中，以石榴皮废弃物作为可持续建筑材料生产烧制粘土砖。为了优化烧制温度和石榴皮废弃物的比例，进行了一系列实验以确定其机械、物理和热性能等基本性能。随后，将获得的热性能用作Design Builder软件版本（V.5.0.0.105）的输入数据，以评估所生产砖块的热性能和能源性能。结果表明，砖块的最佳烧制温度为900°C，石榴皮废弃物比例为10%。由于其导热系数降低，在700°C、800°C和900°C的烧制温度下，所制造的砖块分别降低了6.97%、8.54%和13.89%的能源消耗。在相同烧制温度下，CO排放量也分别降低了4.85%、6.07%和12%。在900°C的烧制温度下，砖块的投资回收期为0.65年。这些发现表明，由石榴皮废弃物制成的烧制粘土砖具有成为一种有前景的建筑材料的潜力，它可以限制热量获取、节约能源、减少CO排放，并能快速收回投资。
