What is ventilation? In simple words ventilation is replacing the air inside a building with fresh air. There are two main types of ventilation systems: Natural ventilation and mechanical ventilation Roofing contractor.
Natural aeration in buildings occurs due to wind and temperature differences between the inside air and outside air. Aeration due to wind is normally seen in the countryside as there are less closely built building. So the wind can easily do its job of keeping a house dry, especially in summer. But in more populated areas where there’s too many building wind can’t do much. Airing due to temperature difference is mainly seen in winter as there’s a considerable temperature difference between the inside and outside of a house, unlike in the summer.
Nevertheless, natural freshening is not enough to properly ventilate most buildings, including houses we live, due to various reasons. One of the main reasons is air pollution. Researchers have shown that 50% of illnesses are caused by poor indoor air quality. And this is increasing by the day. In most modern buildings windows and doors are air tight. Builders use thicker insulation and air tight vapor barriers to ensure there’s not even a tiny leak. This has made modern buildings more efficient, thus saving money and energy. But due to these extra measurements the airing that occurs naturally is almost impossible. But many people do not recognize the downside of it.
For example if a heater breaks in the winter, it’s outright known that and quickly taken care of. But no one notices if the ventilation is good or bad, as most of the times you don’t feel it or you’ve gotten used to it and thus it is not registered to you as a problem. If you are going out of the house better part of the day and when you come back, open the door and get inside, do you feel like air smells different? You’ll not notice it after a few minutes but that is a sign that you don’t have good ventilation systems in your house.
You can’t always let the natural aeration do the job by keeping all the windows and doors open as it is not practical due to various reasons such as security and weather conditions. So the best way to ventilate a building is to set up a proper mechanical ventilation system. Most of the mechanical ventilation systems are low energy consuming. So you don’t need to worry much about the energy consumption. Besides by introducing clean dry air into a building, residents in the building will be healthier and more comfortable, making the happier. Also it provides protection from various types of mold and mildew that can weaken and destroy many structures grows on.
