Abstract

  Currently, Thailand is experiencing continuous economic growth, leading to numerous construction projects for buildings and residences. Construction technology has thus become a significant factor in accommodating this rapid development. One of the most popular technologies for building walls today is the use of prefabricated walls. However, these walls are relatively expensive and not environmentally friendly or suitable for residents' health. Most of the materials used, such as cement powder and EPS foam, negatively impact both the inhabitants and the ecosystem. Additionally, the agricultural industry generates a significant amount of organic waste, which is often discarded or burned, causing environmental pollution. This research aims to study the thermal performance of concrete walls combined with rice husks and bamboo. The study evaluates the thermal efficiency of three test houses, each with walls made from different materials but of the same dimensions: 1.20 x 1.20 x 1.20 m³. The test walls, 10 cm thick, face south and consist of the following configurations: House 1 uses standard Smart Board walls, House 2 uses concrete mixed with coconut fibers, and House 3 uses concrete mixed with rice husks and bamboo. The test results revealed that the average inner wall surface temperatures in each room differed by 1–5 degrees Celsius.
