The topic addressed some important issues such as what is an adequate ventilation rate to ensure that a healthy indoor air quality is maintained within a certain space area.
So after attending last night presentation, the topic that was proposed was, "Do we really need mechanical ventilation within a space?"
Some say that natural ventilation is adequate while some specify and state that mechanical ventilation is compulsory. One thing people do not consider is that natural ventilation may be adequate at times but during the winter time, people tend to close their windows due to the cold temperature outside. So should mechanical ventilation be compulsory in all instances then?
