Dr. Sustainable architecture Courtyards Natural ventilation Humidity -- Control Master of Science in Building Engineering Courtyard is considered a natural alternative for cooling since it has high ability to create a local climate within a building that is nicer than the outside which leads to create temperature difference between indoor and outdoor. The efficiency of courtyard in hothumid climate still questionable due there are minimal research reported especially in Malaysia. The objective of this research is to perform a simulation study using EnergyPlus simulator to explore the influence of the presence of a courtyard in a single storey office building via investigating the impact of natural ventilation, window glazing and window blind shading on the thermal performance of the building on 21 April and 21 October that representing the dry season and wet season days in Malaysia. The Development Department building at University Malaysia Perlis (UniMAP) that is located in Pauh Putra Campus has been taken as a case study. The results show that the stack ventilation is the most effective way to reduce the indoor air temperature due to its high ability on exchanging the indoor warm air with the cooler one in the courtyard. In contrary, the cross ventilation has the greatest impact on reducing the relative humidity within the building since it is capable to dilute the moist concentration in the interior spaces as a result of airflow. The best PMV values for ventilation effect is obtained for stack ventilation, indicating its effectiveness in enhancing the thermal comfort of the building. Moreover, venetian blind shading is capable to reduce the indoor air temperature for the building and using external blind is more effective due to its impact on blocking sun radiation. Additionally, the external venetian blind causes to increase the relative humidity within the building compared to no window shading case due to the reduction of air temperature. Generally, window shading reveals an enhancement on PMV values and the external blind has the most effective where it is capable to shift PMV values within comfortable level during wet season, but it does not much impact on the thermal sensation level during dry season. Using double and triple glazing windows able to reduces the indoor air temperature and in contrary, relatively increases the humidity within the building compared to using single glazing window. The PMV values of glazing effect revealed that using multi-layered glazing window slightly enhances the thermal sensation for occupants but it is not able to reduce the uncomfortable hours on both design days. Finally, it can be observed that the ventilation is the most effective factor on reducing the air temperature and relative humidity, as well as to enhance the thermal comfort level for courtyard buildings in hot-humid climate among the other studied parameters. This work contributes to sustainable architecture where courtyard application concept is used in hot-humid climate specifically for Malaysia due to its effective ability to enhance the thermal performance and help in improving the thermal comfort level near to the desired values. 2018 2023-03-06T06:23:51Z 2023-03-06T06:23:51Z Thesis http://dspace.unimap.edu.my:80/xmlui/handle/123456789/78004 en Universiti Malaysia Perlis (UniMAP) Universiti Malaysia Perlis (UniMAP) School of Environmental Engineering |
