Figure Q2 shows the example of typical terraced houses in a dense urban environment in Malaysia. As a sustainable method for indoor cooling, natural ventilation is a sustainable solution to reduce the energy consumption caused by the air-conditioner system. However, the terraced houses often face a problem of lack of natural ventilation for comfort or structural cooling (i) Based on the above statement, explain THREE (3) factors that potentially affect the natural ventilation performance in the terraced house (ii) (12 marks) With the help of sketches, propose the ideal ventilation method (either naturally, mechanically, or both) that can be implemented in the terraced house to improve the ventilation rate and reduce the heat.
