“…It has the advantage of including the major factors affecting occupants' thermal sensation regardless of the HVAC system, indoor thermal environment, activity, or clothing level. However, Sharifi et al [29] explain that PMV overestimates thermal sensations in warm climates without considering human acclimatization. PMV also has the delimitation of not being able to evaluate occupants' perception, hence the need for thermal sensation vote (TSV), as utilized in this study.…”

“…Likewise, the PMV scale is the only scale correlated to TSV that can convert the verbal ranges to numerical values. According to Sharifi et al [29], TSV allows for the evaluation of occupants' thermal sensation and is based on the individual's thermal perception. Another major reason for the discrepancy between TSV and PMV is that it is difficult to measure accurate values for metabolic rates and clothing insulation [33].…”

“…The predicted mean vote (PMV) estimates the mean response of occupants to their thermal environment and was determined using six parameters: air temperature, mean radiant temperature, relative humidity, air velocity, clothing insulation level, and metabolic rate. The thermal sensation vote (TSV), on the other hand, is the actual thermal sensation vote of the occupants and is obtained from the results of the thermal comfort survey by asking the occupants to vote on how they felt in relation to the ASHRAE seven-point thermal sensation scale [29]. During the field investigation, each participant took part in a single experimental session in their living rooms.…”

“…These values were calculated using the BS EN ISO 7730 standard [28]. This shows that their clothing and level of activity did not exaggerate their thermal perception [29,30]. All participants from the bottle house indicated a TSV of −2 (cool), while responses from participants in other house types ranged from 0 to 3 (neutral to hot), with those in the cement houses (CH 1 and 2) indicating only +2 and +3 (warm; hot).…”

“…Furthermore, this paper compares the results obtained to typical building typologies found in the study area. Post-occupancy evaluations to monitor indoor environmental conditions and assess occupants' thermal comfort using surveys have similarly been carried out by [25,28,29] using PMV and TSV thermal comfort models. BS EN ISO 7730:2005 [30] describes the predicted mean vote (PMV) as an index that predicts the mean value of the votes of a large group of persons exposed to the same environment on a seven-point thermal sensation scale (Table 1) based on the heat balance of the human body [31].…”

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.
