One of the main design tasks of indoor space is to achieve human comfort. Cross ventilation systems are numerous but to propose a natural system that could be easily applied in different weather conditions is challenging. This study focuses on how to apply cross-ventilation by the direct and indirect driven wind. The research aims is to enhance design decisions by utilising venturi or stagnation conditions. This can be achieved by different openings and wall distributions that can help control wind velocities naturally in indoor spaces hence providing human comfort and at the same time save energy. By utilizing a simulation tool (ANSYS), it was found that in a moderately hot climate zone slightly windy, by a simple venturi proposed air velocity intervention air velocity can increase up to 42% of average outdoor air velocity between 2m/s and 8 m/s and by utilizing stagnation condition air velocity can reduce up to 55% of average outdoor air velocity between 2m/s to 8 m/s. The main aim of this research is to propose a design prototype for different types of indoor space such as hotel room prototypes to achieve natural comfortable ventilated living spaces.
