A phenomenon of global climate change and global warming led to an increase of study on indoor thermal comfort as it causes an increase in air temperature in both outdoor and indoor environments. Thermal comfort of indoor condition had a significant impact on occupants' performance, especially in the educational building. The impact is more crucial in a natural ventilated building as it is influenced by both outdoor and indoor condition. This paper presents an overview of a study on thermal comfort over the past ten years in the classroom that use the passive ventilation system. The study is divided into two sections; the first reviews the variables that are measured to determine thermal comfort and the second section reviews the other factors that could influence the thermal comfort. The factors that have been reviewed include climatic condition, design of ventilation system of the building, building envelope design and occupants behaviour that had influence the thermal comfort in the building, hence influenced the occupants' performance. Most of the studies had found that the occupants were dissatisfied with the indoor environment and the results of the studies found that thermal comfort is not in the comfort range, as stated in the standards. The ventilation factor has been highlighted in most studies to be the crucial factor that influences the indoor environment and thus influence the thermal comfort of the building.
Abstract. The implementation of daylighting strategies in buildings is a common aspect in architecture. However, due to the availability of inexpensive electricity, natural lighting strategies became insignificant, and been overlooked by designers. With the current concern over rapid increment on electricity cost, many designers now try to revitalized daylighting strategies in buildings. This includes educational buildings. In Malaysian cases, it is a norm that universities; especially during lecture and studio sessions, used artificial lighting throughout the day. Definitely, this is not parallel with the "green" aim made by the Government in the Malaysian Plan. Therefore, this paper aims to explore the impact of daylight strategies for educational studios in universities, by maximising the penetration of natural daylight into the space towards creating a more green-conducive studio. The paper review literature about the types, criteria and benefits of daylight strategies. This paper also presented a pilot study that has been performed in one university in Perak, Malaysia, by selecting architectural studios as the main subject.
The Prevention through Design (PtD) concept has been widely used to mitigate potential safety and health hazards and minimize residual risks during the early design phase. Integrated Project Delivery (IPD) prioritizes project-wide collaboration and coordination; therefore, the importance of PtD has been widely recognized. There are still neglected issues pertaining to the implementation of the PtD concept from the architectural perspective. Hence, to fill this research gap, this review was motivated to highlight the ontological framework of PtD practices in the construction industry from the architectural perspective. The study is a thematic review aimed to synthesize the literature from 2011 to 2022 on the PtD concept from an architectural perspective. The study, using ATLAST.ti 8, a keyword search, followed by a filter using inclusion criteria from Scopus, Science Direct, Web of Science databases, and the snowball method, identified and analyzed 93 peer-reviewed journal articles. However, only 41 articles were used in the final review after the inclusion and exclusion process. A thematic review of these 41 articles identified five clusters representing the ontological framework findings, namely (1) designer competency, (2) planning and design decision making, (3) technologies related to building safety, (4) design features and workplace condition, and (5) laws and building legislation. The finding is expected to improve the understanding and implementation of the PtD concept to further develop an architectural safety design framework.
This paper provides strategies in evaluating usability via accessibility from the user experience of three replacement hospitals. The methodology refers to a five-stage evaluation process and using the “walk-through journey experience” among patient and visitors. The data analysis was based on thematic analysis principles using NVivo9. The accessibility design issues due to participant disabilities and expectation will build up for usability parameters. The findings indicate that the quality design is the positive user experience feedback on the usability of the physical design environment that fulfils their expectations and the concept of usability and accessibility is to support the user-friendly environment design.
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.
