Every building regardless of whether commercial or residential, requires sufficient ventilation to safeguard the health of those who live there in normal circumstances, and in emergencies, such as fires, or other airborne pollutants.
There are a variety of systems for ventilation, the two major systems currently being mechanical and natural ventilation. Each is distinctly different in the way it is functioning, and also the benefits and drawbacks they bring to the structure it's built into or installed into.

Natural ventilation is any system that doesn't need mechanical devices to move air inside the structure but instead uses organic airflow and ventilation openings to draw pollutants and old air out of the structure.
This is the initial of the five major advantages this system provides – possibly reduced installation costs in comparison to mechanical systems. This is only applicable to certain situations however if a successful system is designed as a part of the structure before construction, then the cost is integrated into the building.
It is important to note that mechanical systems could provide better value when having the largest surface area is essential to get the highest commercial profit, such as on car park sites, certain retail areas, and similar places.
The other benefit of natural ventilation is that its budget-friendly mechanical equipment is expensive to run, not only due to the necessity of ventilators but due to the need for air conditioning units that can raise energy costs by as much as 30% per structure according to studies.
