The use of natural ventilation components as an enhancement for the ventilation systems has become more desirable in the building sector. The natural ventilation systems play a crucial role in reducing the carbon footprint from space heating and cooling through applications of low carbon technology and heat recovery unit. Low carbon technologies such as windcatchers and turbine ventilators are commonly used in commercial, educational, and industrial buildings for providing thermal comfort within a building and minimising carbon emissions. This study proposes to investigate a new concept of home ventilation systems integrated with a vertical axis wind turbine. The study aims to achieve a more detailed understanding of the proposed system in terms of ventilation performance for both air extraction and supply of air by a turbine ventilator type. The simulation results of the proposed design of a turbine ventilator to meet the Building Regulation’s minimum ventilation rate requirement are presented. Having considered a wind speed at 6 m/s, the maximum exhaust flow rate induced by the turbine ventilator was captured at 87.52 l/s, whereas the maximum air supply flow rate of 38.25 l/s induced by the air intake vent (AIV) was observed. To improve performance of the AIV, the simulation results of two modified versions (AIV1 and AIV2) show an increase in supply ventilation rate of 5% and 20% for the AIV1 and AIV2 respectively. As the proposed turbine ventilator is a primarily design, the results from this study indicate a promising potential of the ventilation system combined with a powerless turbine ventilator for domestic dwellings.
