“…Although in these spaces the use of suspended ceilings contributes to thermal regulation, a greater wind flow would dissipate the excessive heat gains caused by the expulsion of metabolic heat from the users and the accumulation of solar radiation on the walls of the building (García-Chávez and Fuentes-Freixanet, 2005). Wind circulation would contribute to the thermal comfort of users exposed to hot and humid conditions that affect work performance and the development of their daily activities (Zhai et al, 2017;Bin Nadeem et al, 2022). In the outdoor space, the averages of air temperature, relative humidity and wind speed were 32.9 °C, 69.3 % and 1.2 m s -1 (Table 5).…”

“…The use of materials with high thermal transmittance, such as concrete and clay blocks, cause unfavourable thermal variations in housing, particularly in tropical climates (Velez et al 2014;Giraldo-Castañeda, Czajkowski and Gómez, 2021). This increases energy consumption due to the excessive use of air conditioning systems such as air conditioners in hot climates and heaters in cold climates (Bin Nadeem et al, 2022;Balter et al, 2021;Hermawan and Svajlenka, 2022). In addition, global warming is changing the microclimate of urban contexts, particularly in residential areas (Therán and Rodríguez, 2018;Pérez-Arévalo et al, 2023).…”

The aim of this research is to analyze thermal comfort and microclimate for indoor spaces in low-rise residential buildings in dry tropical climate. The study area is the municipality of Palmar de Varela in northern Colombia. The experimental methodology is based on measuring three microclimatic parameters: air temperature (Ta), relative humidity (RH) and natural ventilation (W). The study assessed the thermal sensation in indoor spaces based on Thermal Sensation Vote (TSV) and Predicted mean vote (PMV). Data gathered from surveys were analyzed with data mining technologies. The findings suggest that suspended ceilings and ceramic tiles aid to the thermal equilibrium of the building, resulting in a 1.1 °C decrease in indoor air temperature. Likewise, the correlation between temperature and wind (r = -0.72; -0.56) indicates that natural ventilation in buildings can alleviate thermal discomfort. Based on the thermal sensation evaluation, the predominant feeling reported by interviewees in indoor spaces was warm (2) in S1 and S2, and slightly warm (1) in S3. In addition, the correlation between air temperature and comfort sensation in indoor spaces (r = 0.64; 0.44) suggests that temperature has a direct impact on thermal sensation votes.

“…The interior design temperature of 24°C is used for the calculation of the cooling load during the summer because the indoor dry bulb temperature should range between 21 and 25°C to satisfy the standards for thermal comfort. 59 For the purpose of calculating the cooling load of the sample residential area, four parameters namely, heat transfer coefficient of glass, window orientation, window to wall ratio, and infiltration ACH value are chosen for four distinct values.…”

Better insulation or material with low thermal conductivity is a crucial factor in new construction and retrofitting existing structures where energy efficiency is the objective. Effective energy savings need the careful selection of construction materials to accomplish this. For this purpose, in this research work, a typical residential flat is taken into account. Using the hourly analysis program (HAP 4.90) software, the cooling and heating load is determined. Eight influencing factors, including building orientation (A), overall heat transfer coefficient of wall (B), roof insulation material (C), roof insulation thickness (D), heat transfer coefficient of glass (E), window to wall ratio (F), air infiltration flow rate (G), and bypass factor of air-conditioner (H) at three levels, are chosen to optimize the cooling and heating load. An orthogonal L27 layout is considered for the optimization, and the cooling and heating load has been determined for each experimental attempt. At first using Taguchi method, ANOVA analysis is done separately for each response variable and later using GRA and TOPSIS based Taguchi analysis, multi-objective optimization has been done, and the results are compared with each other. By determining each factor’s percentage contribution to the cooling and heating load, the ANOVA approach is also used to identify the primary components that have a major impact on the cooling and heating load. The outcome demonstrates that A3B2C2D3E1F1G1H1 is the best possible combination of all eight variables, and overall heat transfer coefficient of wall is the most influencing parameter for the residential buildings.
