This field investigation of thermal comfort parameters in Green Building Index (GBI)-rated office buildings employing various façade-shading devices compared thermal performance in terms of four main variables: indoor air temperature, indoor relative humidity, mean radiant temperature, and indoor air velocity. Over five days of fieldwork at each building, the four variables of interest were measured, recorded, and analysed using Excel graphs. The results show that the thermal comfort performance of each building was acceptable within the parameters of the GBI Non-Residential New Construction (NRNC) Tools for Indoor Environmental Quality (IEQ). In general, observed values were good for three of the four thermal parameters: indoor air temperature, indoor relative humidity and mean radiant temperature. However, indoor air velocity fell below the acceptable range as defined by the GBI NRNC Tools. One possible reason for this negative outcome is low air exchange from the air conditioning systems in the selected buildings.
The shift in the learning patterns of the current generation motivates the changes in the setting of learning spaces. This research objective is to examine the association between Learning Space attributes with student satisfaction and perceived performance. A survey was conducted in Universiti Teknologi MARA (UiTM), Perak Branch, Seri Iskandar Campus, Malaysia. A questionnaire was administered and collected from 410 students, where respondents were asked to select their preferences based on a five-point Likert scale of agreement and satisfaction. The analysis was conducted using PLS-SEM: Smart-PLS Version 3.2 to examine the measurement and structural model of the research. Results indicated that there is a significant relationship between Learning Space attributes with student satisfaction and perceived performance. The overall findings of this research show that the research variables successfully predicted the model.
Human thermal comfort is the paramount target to achieve the satisfaction of the occupation and users of the building. The frequency of use in the Malaysian religious building, known as mosque, changes daily in different hours and intervals. The first objective of this study is to compare the thermal comfort condition between timber and concrete religious building. The second objective is to analyze the relationship between thermal comfort and worshippers' perception level in the religious building. A questionnaire survey and case study was conducted at various religious buildings in suburban area of Kelantan, Malaysia. The 476 closed structured questionnaires have been given out, and a total of 173 surveys have been achieved. The answers have statically analyzed by using SPSS Version 23.0: descriptive analysis (mean ranking) and multiple regression analysis. The result shows that majority of the respondents have chosen the concrete mosque as their preference to perform prayer instead of timber mosque. It is hoped that this study will give benefit for worshippers towards thermal comfort to achieve the thermally comfortable environment in mosques building.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
