“…From Table 7, it can be observed that the average air temperature for the bottle house over the measurement period was 32.2 • C, and the mean radiant temperature was 32.7 • C, with an operative temperature of 32.45 • C. These values are much lower than those recorded in the other dwellings. This could be attributed to the overall components of the building envelope in the bottle house having higher thermal resistance compared to that of the other dwellings [21]. This improved thermal performance is also evident in the PMV, with the bottle house also recording a lower percentage of persons dissatisfied (PPD) than the other dwellings.…”

The external walls were constructed with a thickness of The thermal transmittance (u-values) of the external walls of the bottle house, mud houses, and cement houses were 2.94, 2.62, and 4.0 W/m 2 K, respectively [21]. The bottle house (BH) was built using waste Polyethylene Terephthalate (PET) bottles collected within the local community, which were then filled with sand and water.…”

“…The comprehensive review presented by [19] shows that numerous studies have investigated the thermal performance of upcycled materials for constructing homes; however, these studies have mainly focused on the component level. A few studies [17,20] have predicted the performance of buildings from upcycled materials using simulation and quantitative studies to determine the effect of overheating in such buildings [21]. Tarabieh et al [17] evaluated the thermal performance of sand-filled plastic bottles using a simulation study and compared it to traditional composite brick walls in Egypt.…”

Due to the effects of climate change, diminishing natural resources, and continuous urbanization, there is an increasing need for buildings to be more sustainable. This study explores the potential of upcycling plastic waste for the sustainable construction of low-cost homes in developing countries and contributes to filling the gap in existing studies regarding qualitative results of the in situ performance of buildings made from upcycled materials. This study compares the Bottle house with conventional buildings made of mud and cement. This study seeks to encourage the adoption of the bottle house concept for affordable housing by conducting a thermal comfort survey of its occupants. To obtain the thermal sensation vote (TSV) of the occupants, thermal comfort questionnaires were developed based on the seven-point ASHRAE thermal sensation scale. Additionally, a Testo 480 multifunction meter, which comprised an anemometer, radiant globe thermometer, air thermometer, and relative humidity probe, was used to calculate the predicted mean vote (PMV) concurrently. From the results of the TSV, mean votes of the participants of −2.0, 2.0, and 2.4 were observed for the bottle house, mud houses, and cement houses, respectively. In comparison, adjusted PMV mean values of 1.9, 2.1 and 2.1 were recorded for the bottle house, mud houses, and cement houses, respectively. The TSV and PMV results both indicate that the occupants of the bottle house felt more thermally comfortable when compared to occupants in the other dwellings. This can be attributed to the measures incorporated during the construction of the bottle house. Furthermore, the use of a simulation study helped proffer solutions to further improve the indoor temperatures of the buildings used in this study. The results of this paper will provide evidence of the prospects of upcycling plastic waste for construction and its impact on occupant’s thermal comfort when compared to conventional building materials.

Housing is a fundamental human need, yet access remains a significant challenge in Africa, particularly for low-income families. Rapid urbanization exacerbates this issue, highlighting the need for innovative and sustainable housing strategies that can support urban growth and improve living conditions for these families. This study employs a rapid review methodology to identify and analyze sustainable innovative affordable housing (SIAH) strategies suitable for low-income families in African cities. Through a comprehensive literature search and thematic analysis, the review explores housing strategies such as mixed-use developments, incremental housing, low rental housing, inclusionary housing, 3D printing, upcycling, micro-housing, community-led housing, co-housing, and green building practices. These approaches/strategies are not mutually exclusive and can often overlap or be integrated to address housing challenges comprehensively. The findings highlight that these strategies can significantly enhance spatial justice and promote sustainable urban development. However, challenges such as material scarcity, regulatory complexities, and societal resistance must be addressed. The study emphasizes the need for policy support, public–private partnerships, community engagement, financial incentives, and capacity building to ensure successful implementation of these strategies. The paper contributes to the existing body of knowledge by providing actionable recommendations for policymakers, urban planners, and housing advocates, aiming to foster inclusive, equitable, and sustainable cities in Africa. Future research could delineate the strategies into distinct categories based on their nature and purpose (strategy, method/tool, practice etc.), providing a clearer framework for understanding and implementation.
