Use of Natural Ventilation in Malaysia's Future Green Housing

Abstract

Within the Asia Pacific region, Malaysias WAWASAN 2020 creates the vision of being a green country. Accordingly, the Malaysian Government has established the mission of reducing the carbon emission. The programs include the projects targeting the energy efficiency and saving within the housing and residential buildings that must meet the Green Building criteria to achieve the sustainable architectural design. Renewable energy sources, like wind or solar energy, can be used to ventilate. The review of previous researchers shows that the use of the natural ventilation system decreases the electricity consumption of a simulated housing in the hot and humid climatic conditions such as Malaysia. The purpose of this research is a review of consumes renewable energies such as solar energy and wind for passive cooling. To test the benefit of natural ventilation system, this paper reviewed some analysis that had used simulation software such as CFD.

Thermal Comfort Performance of Naturally Ventilated Royal Malaysian Police (RMP) Lockup in Hot and Humid Climate of Malaysia

“…Ventilation through an efficient window's opening either by cross ventilation or stack effect approach as well as a combination of other passive ventilation systems are able to ensure thermal comfort factors such as air temperature, air speed, air humidity and temperature radiation are achieved (Gharakhani et al, 2014). This thermal comfort can also be achieved and experienced regardless of types of clothing worn and individual metabolism rate during any of activities carried out by individual.…”

“…The average daily temperature during this period of time is considered high which is between 31.2°C to 33.2°C (World Meteorological Organisation, 2020). Physical measurement at this point of time is strongly recommended to understand better on thermal comfort of the lockups in hot and humid climate region (Gharakhani et al, 2014;Xue et al, 2016).…”

“…All physical measuring instruments used in this study follow ASHRAE Standard 70 or 113 or ISO 7726. As stated in Table 7, the physical measuring instruments have been placed at the center of the bed (center of the lockup) as it is the main area which usually occupied by the detainees especially for sleeping, sitting, and standing 7 as it is more relevant for this study and recognized globally (Gharakhani et al, 2014;Xue et al, 2016).…”
