Published by Elsevier Ltd. Procedia - Social and Behavioral Sciences, https://doi.org/10.1016/j.sbspro.2015.01.063. According to AHSRAE (2010), the recommended value of thermal comfort is 24°C and the value of relative humidity is between 40% to 60%. Introduction. Hence, the studies above demonstrated that natural ventilation certainly provides effects to the indoor thermal comfort. Corpus ID: 29993705. In this study, we aimed to determine the summer comfort temperatures in offices in Malaysia, Indonesia, Singapore, and Japan. Copyright © 2015 The Authors. The human body will release excess heat into the environment, so the body can continue to operate. In a tropical climate, passive cooling is difficult to achieve with respect to mass housing design. et.al (1997) Overheating in Malaysian Houses, Proc.Affordable Quality Housing, Samad et.al., UPM, Serdang Selangor, Malaysia. Recommended articles lists articles that we recommend and is powered by our AI driven recommendation engine. The hot working environment in the industrial increases the challenges of body homeostasis to induce heat stress and interferes with thermal comfort. The results indicated that the design of single storey terraced houses is not effective in providing natural ventilation for achieving thermal comfort. Abstract and Figures In hot-humid climate, the mosque should be provided with an acceptable level of thermal comfort in order to seek serenity and focus for worship. 3099067 Peer-review under responsibility of Centre for Environment-Behaviour Studies (cE-Bs), Faculty of Architecture, Planning & Surveying, Universiti Teknologi MARA, Malaysia. Copyright © 2021 Elsevier B.V. or its licensors or contributors. 4 the average peak temperature (indoor dry-bulb) of the 5 working days in LEO building (14. th to 18th of September) was 22.0°C at the 15:00h, when outdoor temperature was 30.2°C with a … Overall, indoor temperatures are higher than the indoor design conditions recommended in Malaysian Standard; MS1525:2007. Yau YH (1), Chew BT. This study examines the level of the thermal environment in residential building in Malaysia at various urban micro-climates which are Kuala Lumpur (KL), Bayan Lepas (BL) and Kuching (K). A simulation model of a typically-designed residential building in Malaysia was constructed to determine the indoor temperatures in the indoor living spaces, namely living cum dining area (DL), wet kitchen (K) and master bedroom (MB). The highest mean comfort temperature is 27.5 °C with mixed mode ventilation. Registered in England & Wales No. thermal comfort problem. The results showed that 49% of the occupants were satisfied with the thermal environments in the hospitals. 1997), and 28.5°C (Gail and De Dear 1998). Malaysia is a tropical climate country with hot and humid condition throughout the year. Researches on thermal comfort at higher humidity levels were mostly carried out in climate chamber or air-condi- tioned spaces. Earlier studies showed that the outdoor thermal comfort range based on physiologically equivalent temperature (PET) index in Malaysia is less than 34°C, thus the data obtained were classified into two state: normal state (within thermal comfort range) and hot state (above thermal comfort range). Abstract and Figures This paper presents the main findings of the effect of indoor humidity on occupants' thermal comfort in the humid tropics of Malaysia. A field study on the environmental condition and occupants' thermal comfort has been carried out in Hospital University Kebangsaan Malaysia (HUKM). This article presents findings of the thermal comfort study in hospitals. Research on terraced house in Malaysia by (Zain, Taib, & Baki, 2007) proposed that the thermal comfort could be achieved below 28.69qC. conditions of thermal comfort in Malaysia (refer to Table1). Measured indoor climates were also recorded. Keywords: thermal comfort, tropical climate, urban village, outdoor spaces, Malaysia Low air velocity and high air temperature are experienced during the daytime and the wind effect is not well captured, especially in the single sided ventilation. Candidate, Faculty of Built Environment, Universiti Teknologi Malaysia, Johor DT, Malaysia, Associate Professor, Faculty of Built Environment, Universiti Teknologi Malaysia, Johor DT, Malaysia, Lecturer, Faculty of Built Environment, Universiti Teknologi Malaysia, Johor DT, Malaysia, Journal of Asian Architecture and Building Engineering. A total of 890 individuals were asked to complete a questionnaire. This humidity is among the indoor environmental factors that could affect thermal comfort in a building. When people are dissatisfied with their thermal environment, not only is it a potential health hazard, it also impacts on their ability to function effectively, their satisfaction at work, the likelihood they will remain a customer, and so on. Abstract This article presents findings of the thermal comfort study in hospitals. The simulations were performed on a selected day in a one–year climate condition. In this study, the lower and upper air temperatures for thermal comfort was taken to be 26 θC and 23 θC, respectively, as according to Department of Standards Malaysia, 2007. The International Standards such as ASHRAE ISO 7730 Standard 55(deDear et al) is often used to determine the thermal comfort condition in a building by the architects and professionals. The field survey analysis revealed that the neutral temperature for Malaysian hospitals was 26.4°C. Proposal Defense: Outdoor Thermal Comfort and Adaptation for Pedestrian in Towns of Malaysia 6 Thermal Comfort and Indoor Air Quality Evaluation of Hospital Patient Ward in Malaysia @inproceedings{Azizpour2013ThermalCA, title={Thermal Comfort and Indoor Air Quality Evaluation of Hospital Patient Ward in Malaysia}, author={F. Azizpour and S. Moghimi and E. Salleh and C. H. Lim and K. Sopian}, year={2013} } 1993). Thermal Comfort of Residential Building in Malaysia at Different Micro-climates. Therefore, modification of the natural ventilation mechanism using a solar chimney as induced ventilation needs to be manifested and evaluated. Other study reported that the comfort band for Malaysia for all building types is between 23.6 θC and 28.6 θC (Sabarinah & Steven, 2007). MALAYSIA HERITAGE MOSQUE As mentioned before, the heritage building can be of many functions, including religious building such as mosque.

A field survey was conducted to investigate the temperature range for thermal comfort in hospitals in the tropics. The objective of this paper is to study the air quality in lecture rooms by measuring the content of carbon dioxide (CO 2), humidity and temperature. Comfort temperatures were higher than local comfort guidelines, except in Japan. Davis M.P. Deering R.B (1953) Technology of the Cooling Effects of Trees & Shrubs, Building Research Advisory Board, Conference Report No.5, Washington. The human body can be viewed as a heat engine where food is the input energy. People also read lists articles that other readers of this article have read. In Malaysia, a typical single terraced house unit consists of a built-up area of 60 to 65 square Cooling by natural ventilation and passive cooling is a good energy conserving design strategy to improve the indoor thermal comfort and air quality in a tropical country like Malaysia, which has high daytime temperatures of 29–34 °C and relative humidity of 70–90% throughout the year. Thermal comfort in buildings - Designing Buildings Wiki - Share your construction industry knowledge. Other workers recommended similar values, such as 28.7°C (Humphrey 1994), 26.3°C with a clo value of 0.55 (Zain et al. However, it plays an essential role in the design and maintenance of any facility with live occupants. Findings suggest that the highest indoor temperature of 32.6 °C was obtained in a master bedroom (MB) in under KL climate at 1400 hours. 1. Humidity, Thermal Comfort, Malaysia, Humid-Tropics.
