tuuletuksesta

Tuuletuksesta, known in English as ventilation, is the process of replacing or exchanging air in any space to improve indoor air quality. This is typically done to control temperature, replenish oxygen, or remove moisture, odors, smoke, heat, dust, airborne bacteria, carbon dioxide, and other pollutants.

There are several methods of ventilation. Natural ventilation utilizes wind and stack effects to move air through a building, relying on operable windows, doors, and vents. Mechanical ventilation uses fans to actively move air into or out of a space, providing controlled airflow regardless of external conditions. Heat recovery ventilation (HRV) and energy recovery ventilation (ERV) are types of mechanical systems that pre-condition incoming fresh air using the outgoing stale air, thereby saving energy.

Proper ventilation is crucial for maintaining a healthy indoor environment. It helps prevent the buildup of pollutants that can cause or exacerbate respiratory problems, allergies, and other health issues. In addition, effective ventilation can help manage humidity levels, reducing the risk of mold growth and associated health concerns. Buildings can be designed with specific ventilation strategies in mind, or existing structures can be retrofitted with ventilation systems to improve air quality and occupant well-being. The effectiveness of ventilation can be measured by air changes per hour (ACH), which indicates how many times the entire volume of air in a space is replaced within one hour.
