Evaluation of passive cooling methods to improve microclimate for natural ventilation of a house during summer

Tempering potential-based evaluation of the courtyard microclimate as a combined function of aspect ratio and outdoor temperature

“…According to the literature (Abdulkareem, 2016;Aldawoud, 2008;Al-Masri & Abu-Hijleh, 2012Almhafdy et al, 2015aAlmhafdy et al, 2015b;Berkovic et al, 2012;Cantón et al, 2014;Cindel et al, 2018;Del Rio et al, 2019;Du et al, 2014;Ghaffarianhoseini et al, 2015;Guedouh & Zemmouri, 2017Huang et al, 2016Jihad & Tahiri, 2016Ma et al, 2019Manioğlu & Oral, 2015;Martinelli & Matzarakis, 2017Moonen et al, 2011Muhaisen & Gadi, 2006a;Muhaisen & Gadi, 2006bMuhaisen, 2006Nasrollahi et al, 2017;Qaid & Ossen, 2015Rodríguez-Algeciras et al, 2018Rojas et al, 2012;Rojas-Fernández et al, 2017;Soflaei et al, 2016;Soflaei et al, 2017;Taleghani et al, 2014b;Taleghani et al, 2015;Toe & Kubota, 2015Xu et al, 2018Yang et al, 2012;Yaşa & Ok, 2014;Zamani et al, 2018), AR is a key factor in determining courtyard thermal performance. As mentioned before, there are abundant examples of case studies in the literature (Table 1) that analyze the influence of courtyard geometry, specifically their AR, on their potential efficiency as a passive cooling system.…”

“…Some literature reviews have focused on this specific topic (Al-Masri & Abu-Hijleh, 2012;Zamani, Heidari, & Hanachi, 2018;Taleghani, 2018). Most of these studies emphasize the importance of variables such as courtyard geometry, in some cases considered as aspect ratio (AR) or as sky view factor (SVF) (Abdulkareem, 2016;Aldawoud, 2008;Al-Masri & Abu-Hijleh, 2012; C.

Modeling and Validation of the Cool Summer Microclimate Formed by Passive Cooling Elements in a Semi-Outdoor Building Space

“…

Previous measurements (Del Rio et al 2019) have confirmed the formation of cool summer microclimates through a combination of passive cooling elements (i.e., evaporative cooling louver, vegetation, and sunscreen) in semi-outdoor building spaces in Japan. Computational fluid dynamics (CFD) simulation is useful to understand the contribution of each element to semi-outdoor and indoor microclimates with natural ventilation, and to determine their effective combination.

Passive cooling designs to improve heat resilience of homes in underserved and vulnerable communities

“…Many case studies compare the efficacies of alternative passive cooling measures in a specific location, such as Algiers [149], Australia [102,150,151], Brazil [32], Canada [152], China [153][154][155], Egypt [105,[156][157][158], England [126,159,160], Greece [105,161], Hong Kong [26,162,163], India [164][165][166], Indonesia [167], Iran [106,168,169], Italy [26,156], Japan [170], Kenya [164], Malaysia [171,172], Mexico [30], Morocco [86,173], New Zealand [174], Oman [175], Poland [176], Portugal [26,164], Saudi Arabia [26,177], Singapore [26], South Africa [178], Spain [156,…”
