“…4a). Higher temperature difference was achieved in the model integrating PCM layer which indicated an effectiveness of heat flow reduction through the fibercement roof sheets and an achievement of indoor heat accumulation declination [2,15]. This leads to the conservation of energy consumption in buildings [6,7].…”

“…It has been reported that the range of phase change temperature of PCM is an important factor in the selection of a PCM to apply with building envelope for decreasing of cooling load in buildings [2,11,20]. The phase change temperature range of PCM should be lower than the temperature of the building envelope [2].…”

“…The thermal resistance is one of the most important factors when considering the roofing materials, which affects the efficiency in preventing thermal propagation from the outside areas through the roof into the interior space of buildings [2,7,11]. The thermal resistance (R-value) indicates the resistance of heat flow through building envelope material into inside buildings, and varies with the material thickness [7,21].…”

“…Building energy consumption currently accounts for a significant part of the total global energy consumption. However, the important energy saving can be achieved from the optimal design of developed buildings [2]. In the tropical area, the climate is hot and high solar radiation intensity all year-round leads to heat accumulation in the buildings [3].…”

This research focuses on the application of phase change material (PCM) combined with the fiber cement roofing sheet to reduce heat transfer through the building. The experimental study was divided into 4 conditions including the single-layer fiber cement roof (SF), the single-layer fiber cement roof installed with the PCM layer (SF-PCM), the double-layer fiber cement roof (DF), and the double-layer fiber cement roof installed with the PCM layer (DF-PCM). For each condition, the fiber cement sheet was set at an incline angle of 40°with the horizontal plane. The thermal source was controlled at temperature of 60°C, 70°C and 80°C for 360 min to investigate the thermal behavior and compare the heat gain through the roof. The results showed that the DF-PCM could reduce the room temperature by up to 3.1%, 3.8% and 3.7% when compared with the SF, and up to 5.6%, 5.2% and 4.8% when compared with the DF at the controlled heat source temperature of approximately 60°C, 70°C and 80°C, respectively. It indicated that the use of PCM integrated into the fiber cement roofing sheet could reduce the heat transfer and interior room temperature, leading to energy saving.

“…To achieve indoor thermal comfort in the tropical weather, the cooling and heating of the air conditioning system contributes to approximately 65% of the total building energy consumption [1][2][3]. A reduction in thermal accumulation and thermal transmission into the interior of buildings is an alternative solution for reducing the energy consumption demand of cooling load in buildings [4][5][6][7][8]. Wall insulation materials show significant potential in reducing cooling loads in the tropical climates [8,9].…”

This study is concentrated on improving the thermal efficiency of autoclaved aerated concrete (AAC) by incorporation of black powder as an additional component. Black powder is a waste product of the automotive refinishing industry in Thailand. The dynamics of heat transfer and the cooling load of air conditionings in four simulated houses with different wall materials (brick, cement block, AAC, and black powder AAC) were investigated. The results from the comparison of heat fluxes of the interior surfaces demonstrated that incorporated black powder significantly increased the thermal effectiveness of construction materials, as observed from the black powder AAC. In addition, it was demonstrated that the cooling load and the power consumption of air conditioning in the house with black powder AAC walls was reduced, and the power consumption was saved approximately 25.5%, 37.9%, and 48.1% compared with the commercial AAC, the brick, and the cement block houses, respectively. The black powder AAC provided the highest power consumption reduction.
