sisäilmastot

Sisäilmastot refers to the environmental conditions within indoor spaces, encompassing factors that affect human comfort and health. These factors include air temperature, humidity, air movement, and air quality. A well-managed sisäilmasto is crucial for occupant well-being, productivity, and the overall functionality of buildings.

Temperature and humidity are primary components of thermal comfort. Maintaining a stable temperature within a comfortable range and controlling humidity levels, typically between 30% and 60%, helps prevent discomfort and the growth of mold and dust mites. Air movement, while sometimes contributing to comfort through evaporative cooling, can also cause drafts if not managed properly.

Air quality is a critical aspect of sisäilmasto, addressing the presence of pollutants. These pollutants can originate from both outdoor sources, such as traffic emissions, and indoor sources, including building materials, furnishings, cleaning products, and human activities. Common indoor air pollutants include volatile organic compounds (VOCs), particulate matter, carbon dioxide, and biological contaminants like mold spores and bacteria. Adequate ventilation, either natural through windows or mechanical through HVAC systems, is essential for diluting and removing indoor pollutants, thereby improving air quality.

The design and operation of buildings significantly influence sisäilmastot. Factors like insulation, window types, ventilation strategies, and the selection of building materials all play a role. Regular maintenance of building systems, particularly ventilation and filtration, is also key to ensuring sustained good indoor environmental quality. Poor sisäilmasto can lead to a range of health issues, commonly referred to as Sick Building Syndrome, characterized by symptoms like headaches, fatigue, and respiratory irritation.
