The impact of passive ventilation strategies on thermal comfort in large church buildings in hot-humid climate of Abuja, Nigeria
… are mismatched 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 …

Ventilative cooling
… the performance of daytime and nighttime passive ventilation cooling strategies for Beijing, Shanghai and Tokyo. A new simulation method for cross-ventilated wind driven airflow is presented . This method decouples the airflow model from the thermal model allowing for fast real weather …

Design for infectious disease control in the developing world : the power of natural ventilation
… to reduce the spread of contaminants through passive ventilation strategies. Using Computational Fluid Dynamics, I propose a system of hospital rooms which minimizes contaminant spread among patients while maintaining comfortable airflow rates.

An investigation of selected effects of environment on the dry rot fungus <i>Serpula Lacrimans </i>
… When respective treatments by fan drying and passive ventilation were compared, the former were more effective, but its efficacy could be augmented by incorporating low-level passive ventilation via discreet vents. In this manner, a successful remedial treatment of <i>S. lacrymans</i> could be …
