Abstract

Natural ventilation becomes a more popular method to implement in modern buildings nowadays because of its potential to reduce energy consumption and carbon footprint. However, thermal comfort conditions should not be sacrificed in order to achieve energy saving objectives. This research aims to study the potentials of implementing natural ventilation in Malaysia's modern residential building to reduce energy consumption from air conditioning systems. Computational Fluid Dynamics methods were used to simulate air ventilation behaviour in a master bedroom from double storey cluster house in Melaka, Malaysia. The method was validated with a similar research done in China published recently. Three methods were proposed to find the best ventilation performance in terms of air temperature and wind speed. The 2°C increment of air-conditioning setting temperature and increasing air speed from 0.501 mis to 1.25 mis at wall air-conditioning unit shows the best performance among three methods proposed to achieve thermal comfort condition. None of the proposed methods achieves 80% of ADPI satisfaction percentage as recommended in the ASHRAE 55 standard but three of four simulation runs in this research improved the thermal comfort level compared to control condition.
