Sisäilmaston

Sisäilmaston refers to the indoor climate conditions within a building. It encompasses a range of factors that affect the comfort, health, and productivity of occupants. Key elements of sisäilmaston include air temperature, humidity, air quality, and air movement.

Temperature is a primary determinant of thermal comfort. Maintaining an optimal temperature range, typically between 20-24 degrees Celsius for most activities, is crucial. Humidity levels also play a significant role; excessively dry air can irritate mucous membranes, while high humidity can promote the growth of mold and dust mites. The ideal relative humidity is generally between 30-50%.

Air quality is another critical aspect. This involves the presence or absence of pollutants such as volatile organic compounds (VOCs) from building materials and furnishings, particulate matter from outdoor sources or indoor activities, and biological contaminants like mold spores and bacteria. Adequate ventilation is essential for diluting and removing indoor air pollutants and replenishing oxygen.

Air movement, or air velocity, contributes to the sensation of comfort by aiding in heat transfer and preventing stagnant air pockets. However, excessive air movement can lead to drafts and discomfort. The balance of these factors—temperature, humidity, air quality, and air movement—collectively defines the sisäilmaston and its impact on the indoor environment. Effective design, construction, and building management are necessary to achieve a healthy and comfortable sisäilmaston.
