Experimental simulation of wind driven cross-ventilation in a naturally ventilated building
A device was designed and constructed to simulate cross-ventilation through a building due to natural wind. The wind driver device was designed for use with a one tenth scale model of an open floor plan office building in Luton, England. The air flow patterns produced by the wind driver were …

CFD analysis of airflow patterns and heat transfer in small, medium, and large structures
… Previous research has not modeled natural ventilation situations that challenge common design rules of thumb used for cross-ventilation and single-sided ventilation. The current study uses a commercial code (FLUENT) to simulate cross-ventilation in simple structures and analyzes the flow …

Enhancing indoor air movement through roof design: a process of increasing thermal comfort in hot humid region housing
… in the hot humid region impossible. Natural ventilation, therefore, is not only important, but the velocity of air that gets into the living area is crucial. Various ways of creating negative pressure (a process of increasing the interior air speed) are examined. The performance of roof types …

Modeling on single-sided wind-driven natural ventilation
… a significant part of this energy being used for ventilation and cooling. Despite the large amount of energy used in buildings, reports have shown that the indoor air quality (IAQ) and thermal comfort are not satisfactory. The lowered productivity due to the bad IAQ could cause $125 billion loss …

CFD and Deep Learning Based Natural Ventilation Analysis in Buildings
Natural ventilation is crucial for sustainable buildings and is also a promising solution for addressing indoor air quality (IAQ) issues such as those related to COVID-19. This thesis examines the efficacy of wind-driven cross-ventilation for a low-rise residential building with complex geometry …

Natural ventilation through windows in a classroom (CFD analysis crossventilation of asymmetric openings: Impact of wind direction and louvers design)
Natural ventilation is one of the most effective parts of sustainability. In fact, it can improve thermal comfort to expand the comfort zone area. Designing an optimum natural ventilation system is not so simple, however, it has a long-lasting effect on human health and economic benefit. There are …

The impact of passive ventilation strategies on thermal comfort in large church buildings in hot-humid climate of Abuja, Nigeria
… with inadequate and ineffective passive ventilation strategies. Compounded by unreliable electricity and the high cost of mechanical cooling, this creates a widespread challenge to occupant well-being and energy resilience. This study therefore investigates practical, low-energy passive …

Buildings in a hot climate with variable ventilation at night
… phenomena could be exploited by nocturnal ventilation to cool the building fabric, thus saving energy during the day and providing comfort at night. The procedures to evaluate thermal performance of buildings with special reference to nocturnal ventilation are studied. Various approaches to …

An investigation into turbine ventilators as a potential environmental control measure to minimise the risk of transmission of tuberculosis - a laboratory and field study
… in the air until they are removed by dilution ventilation or other disinfection methods (Parsons, Hussey, Abbott, & de Jager, 2008) (National Department of Health, 2007). Dilution ventilation refers to the dilution of contaminated air with “clean” air (ACGIH, 2005), thereby reducing the …
