Natural wind driven sustainable ventilation system (prototype)‎ for indoor living spaces

Abstract EN

One of the main design tasks of indoor space is to achieve human comfort.

Crossventilation systems are numerous but to propose a natural system that could be easilyapplied in different weather conditions is challenging.

This study focuses on how toapply cross-ventilation by the direct and indirect driven wind.

The research aims is toenhance design decisions by utilising venturi or stagnation conditions.

This can beachieved by different openings and wall distributions that can help control windvelocities naturally in indoor spaces hence providing human comfort and at the sametime save energy.

By utilizing a simulation tool (ANSYS), it was found that in amoderately hot climate zone slightly windy, by a simple venturi proposed air velocityintervention air velocity can increase up to 42% of average outdoor air velocitybetween 2m/s and 8 m/s and by utilizing stagnation condition air velocity can reduceup to 55% of average outdoor air velocity between 2m/s to 8 m/s.

The main aim ofthis research is to propose a design prototype for different types of indoor space suchas hotel room prototypes to achieve natural comfortable ventilated living spaces.
