Almost all buildings built before the 21st century featured natural ventilation, but many of these have been retrofitted with mechanical ventilation systems and wall partitions. In recent years, the focus on reducing energy consumption to prevent environmental degradation has reverted attention to using natural ventilation. It is considered a cost-effective method of creating an acceptable indoor climate that will foster productivity and maintain comfort. If the climate is favorable, augmenting mechanical air-conditioning with natural ventilation can help save up to 30% of the energy used.
A natural ventilation system relies on the pressure difference between indoor and outdoor environment to force air into buildings. Natural ventilation can be as simple as wall openings and windows with built-in window controls for hard to reach areas. In large commercial buildings, openings are placed strategically depending on the requirements of the establishment. A natural ventilation system is similar to a circuit where the supply of air and corresponding exhaust are equally considered and given importance
The effective use of natural ventilation in large commercial buildings is made possible through passive dynamics using any of the following five techniques:
These five techniques of passive air movement have working principles used in traditional building design but are being revisited by many architecture firms designing modern skyscrapers around the world. An impressive illustration of the contemporary use of natural ventilation is the Kunming Tower in China which is considered as the tallest building in the world that uses natural ventilation. It is likely that in the near future, similar large-scale constructions will adapt natural ventilation as a way to mitigate energy consumption and reduce carbon emissions, especially in highly congested cities.
