Abstract
Ensuring indoor environmental comfort parameters in relation to indoor air quality requirements necessitates the identification of methods that allow for the development of tools to validate the natural ventilation efficiency in relation to factors that can influence system performance. Analysing the historical evolution of natural ventilation, it is observed that the main identified natural physical phenomena by researchers and design specialists in the field are primarily based on the natural forces that generate the exchange of air between the constructed interior environment and the natural exterior environment. The difference in air pressure on either side of the envelope can be generated by two natural factors, either independently or cumulatively, through the action of the wind and temperature difference.
