Journal ArticleDOI
A review on phase change material (PCM) for sustainable passive cooling in building envelopes
Hussein J. Akeiber,Payam Nejat,Muhd Zaimi Abd Majid,Mazlan Abdul Wahid,Fatemeh Jomehzadeh,Iman Zeynali Famileh,John Kaiser Calautit,Ben Richard Hughes,Sheikh Ahmad Zaki +8 more
TL;DR: In this article, a comprehensive list of different organic, inorganic and eutectic phase change materials appropriate for passive cooling in buildings is reviewed, and full-scale testing and numerical modeling are found to be the most popular investigative methods used for experimental and theoretical analysis of PCMs.
Journal ArticleDOI
Field study on adaptive thermal comfort in office buildings in Malaysia, Indonesia, Singapore, and Japan during hot and humid season
TL;DR: In this paper, the authors collected responses from 325 occupants in 13 office buildings employing various ventilation modes, namely, free running (FR), mixed mode (MM), and mechanical cooling (CL), and found that the comfort range differed for each group of occupants under the different ventilation modes.
Journal ArticleDOI
A review on windcatcher for passive cooling and natural ventilation in buildings, Part 1: Indoor air quality and thermal comfort assessment
Fatemeh Jomehzadeh,Payam Nejat,John Kaiser Calautit,Mohd Badruddin Mohd Yusof,Sheikh Ahmad Zaki,Ben Richard Hughes,Muhammad Noor Afiq Witri Muhammad Yazid +6 more
TL;DR: In this article, the authors compared different theoretical and experimental methods employed by researchers in different case studies to assess the indoor air quality (IAQ) and thermal comfort aspects of windcatchers and found that satisfactory IAQ were generally achieved using the windcatcher.
Journal ArticleDOI
Thermal comfort and occupant adaptive behaviour in Japanese university buildings with free running and cooling mode offices during summer
TL;DR: In this article, the authors present the results of studies on the thermal comfort and adaptive behaviour of occupants in university buildings with free running (FR) and cooling (CL) mode offices in Fukuoka, Japan.
Journal ArticleDOI
Adaptive thermal comfort in university classrooms in Malaysia and Japan
TL;DR: In this article, the authors investigated the comfort temperature and adaptive behaviour of university students in Malaysia and Japan, and found that the most common activity observed amongst Malaysian students was changing the AC temperature setting, due to the prevalence of mechanical cooling (CL) in Malaysia.
