What is Natural Ventilation?
Natural ventilation occurs when the indoor climate of a building is controlled by fresh air through the facade and/or roof windows, which open and close automatically to adjust to target levels for indoor temperature and CO2 levels.
How is natural ventilation achieved?
Natural ventilation is achieved through controlled openings in the external facade of the building, based on different indoor and outdoor conditions. Systems regulate the indoor climate by means of measuring wind pressures, temperature differences and using the shape of the building.
What are the benefits of natural ventilation?
Decreased CO2 levels and fresh air in schools and office buildings have been proven to be more conducive for learning or working environments and significantly improve productivity. Children’s ability to learn increases by up to 15% with the provision of a good indoor climate (International Centre for Indoor Environment and Energy).
Approximately 90% of the average person’s time is spent indoors. The air in a naturally ventilated room feels fresher than in traditional ventilation solutions because there may be some variation in temperature and air circulation as it would occur naturally outdoors. For this reason, greater comfort levels are achieved in naturally ventilated buildings than with mechanical indoor solutions.
