Proper ventilation in any type of building is very important to the health of everyone who lives or works in the space. Indoor air quality can make a huge difference in the way people feel, both in terms of physical well being and mental balance. For this reason, making use of various methods of room ventilation is key to the design of any interior space.

The most basic of all types of room ventilation is natural ventilation. A common approach to this method is the strategic installation of windows within the room. Assuming that the windows can be opened and closed at will, it is possible to allow fresh air into the space whenever desired. Opening windows from time to time makes it possible to rid the space of stale odors, as well as allow different types of airborne pollutants to be expelled from the home or office with relative ease.

While open windows are an excellent example of room ventilation, they are not always the best health option. People with allergies may find that the pollen and other allergens that enter through the open window make the air indoors more of a health threat. In addition, people living in crowded metropolitan areas or in close proximity to some manufacturing facilities may find that open windows create more problems with ventilation than they solve.


Fortunately, there are other ways to achieve room ventilation that do not involve the use of windows that can be closed and opened at will. When windows are not the best solution for some reason, proper room ventilation will require the installation of some sort of air system to routinely refresh the air within the space. One simple solution is the installation of what is known as an exhaust fan. Often used today in residential and public restrooms, the exhaust fan makes it possible to draw stale air from the space while also allowing a small amount of fresh air to enter the room.

More sophisticated ventilation systems are also in use today. Home, offices, and public buildings are often equipped with heating and air conditioning equipment that not only helps to regulate the temperature within the space, but also refreshes the indoor air. Using a system of filters and return vents, fresh air is constantly flowing into the room while stale air is expelled through a different segment of the room ventilation system. The end result is indoor air that is relatively free of allergens, and smells inviting and fresh.

Whether using a simple ventilation fan or a full-scale ventilation system, room ventilation often involves paying close attention to energy efficiency. Fortunately, many systems today are designed to produce maximum results with the least amount of energy consumption possible. As alternative forms of energy become more cost-effective, many homes and businesses are utilizing natural sources like sunlight and wind to effectively keep the air indoors clean and healthy.
