“…Hence, treating roof with layer of insulation is one of the good options, and in this The small-scale building treatments with additional of green roof as insulation layers has the potential to reduce solar radiation as reported by the previous study. This study reported that the material with higher thermal resistance, R-value, will radiates less heat into indoor buildings [38]. Figure 9 depicts the R-values, with the red contour indicating area with the highest R-value, and dark blue contour with the lowest.…”

This study investigates the thermal performance of green roof systems in a tropical climate, focusing on the small-scale building prototypes. Batu Pahat, Malaysia is experiencing the increasing temperatures due to climate change. Green roofs are considered as a potential solution, but their effectiveness depends on various factors such as building orientation, solar shading, and thermal resistance (R-value). Therefore, modeling and simulation are crucial for understanding green roof thermal behaviour. This study employs the Integrated Environmental Simulation Virtual Environment (IES-VE) software for analysis. Three identical small-scale buildings were constructed, one with Portulaca Grandiflora (PGR) plants, another with Alternanthera Paronychioides (ATN) plants, and a control roof with no vegetation. The R-values from the on-site green roofs were measured at 0.8899 m²K/W for PGR and 1.1477 m²K/W for ATN, while the control roof had an R-value of 0.1 m²K/W. Green roofs with higher R-values demonstrated a substantial reduction in indoor temperatures, making them a valuable solution for improving thermal comfort in tropical climates. This study underscores the importance of green roofs in mitigating rising temperatures in tropical climates. Simulation using IES-VE approved that green roofs can potentially reduce indoor temperatures, demonstrating their suitability for tropical regions. These findings have significant implications for sustainable building design and urban planning in hot and humid climates.

“…2 A prior study has explored the thermal performance of insulation panels for construction applications in hot, dry climates, but this research is still in its infancy and has to be expanded in several ways. 3,4 The use of adequate insulation panels in the building envelope is one of the most efficient techniques to minimize the rate of heat transmission and energy consumption to cool and heat buildings. 5 The most common examples of insulation panels used in tropical climate countries are polystyrene panels 6 and gypsum panels.…”

The low performance of insulation panels has received great attention from many researchers and engineers to improve their properties as it has become a limiting factor that minimize their usage specifically as insulation building material. Recently, there has been an increase in interest in the development of composite insulation panels made from natural waste fiber. Due to the abundance of natural waste fiber generated by the agricultural industry, it has made them suitable to be utilized as raw material for composite insulation panels. Having improper waste disposal management might result in these massive quantities of valuable natural waste fiber having a detrimental effect on our ecosystem and contributing to various environmental pollution. A composite insulation panel made from natural waste fibers has unique and versatile features in terms of thermal, physical, and mechanical properties. Seeing such potential, this paper presents a review on the influencing factors towards improving comprehensive properties of composite insulation panels. Factors that influence the properties of the panel, such as the physico-chemical properties of fiber, fiber geometrical structure, and fiber treatment were discussed. Previous and recent research efforts related to factors influencing the properties of composite insulation panels were also compiled. Last but not least, the suitable criteria, limiting factors, and condition of the fiber used in composite insulation panels were also all highlighted.

In order to save energy and reduce building energy consumption, the author pro?posed a study on the impact of composite polystyrene particle thermal insulation mortar on building energy consumption and thermal energy storage, take the ETIRS-C residence as the research object, through simulation calculation under different insulation mortar thickness, analyze the relationship between insulation thickness and energy consumption and thermal environment. According to the simulation calculation of room temperature, horizontally, the thickness of thermal insulation mortar in air conditioning season is not sensitive to the natural room temperature, there is a certain sensitivity to the natural room temperature in the heating season, in the longitudinal direction, the 30 mm thick insulation mortar is the jumping point, and the increase of the thickness of insulation mortar has no obvious effect on the natural room temperature. According to the simulation cal?culation of room energy consumption, the thickness of thermal insulation mortar is about 20 mm, and both heat and cold consumption have achieved good thermal insulation and energy saving effect, further increasing the thickness of thermal insulation mortar will have limited impact on energy consumption, which may be uneconomical and increase the cost and construction difficulty. Therefore, based on the aforementioned results, it can be considered that the thickness of thermal insulation mortar should preferably be controlled within 20-30 mm.
