Abstract

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.
