good for you. The build-up of CO2 inside a building without adequate ventilation can cause a lack of concentration or tiredness. A damaging pollutant, high carbon dioxide levels in your bloodstream can also cause seizures, delirium, difficulty breathing or even respiratory failure. A recent study found that lower levels of CO2 than previously thought pose a risk, with poorly ventilated bedrooms, classrooms and offices typically found to contain higher-than-safe carbon dioxide levels. Ventilate for Better Health A well-ventilated space not only ensures comfort but has also been linked to improved concentration and sleep quality and reduced sick days. The removal of stale air and the introduction of fresh air into a building also helps to remove air containing virus particles. Government guidance on reducing the spread of respiratory infections, including COVID-19, states: “In poorly ventilated rooms the amount of virus in the air can build up, increasing the risk of spread, especially if there are lots of infected people in the room. The risk of airborne transmission is increased when occupants in an enclosed space are participating in energetic activity, such as exercising, or when they are shouting, singing, or talking loudly… Bringing fresh air into a room and removing older stale air that contains virus particles reduces the chance of spreading respiratory infections. The more fresh air that is brought inside, the quicker any airborne virus will be removed from the room.” Adequate air movement in your indoor space is essential to dissipate any nasty, health-threatening particles floating around in your working or living environment. Creating Passive Airflow By using the natural forces of wind and temperature differences, passive airflow can be created through intentional openings, such as doors, windows, or ventilation louvres in walls or doors. Natural Ventilation As air naturally flows from high-pressure to low-pressure areas, natural ventilation airflow can be created by strategically fitting ventilation louvres. Louvre systems are ideal for doors or partitions in offices and classrooms or in doors to plant rooms, stores, computer rooms, changing facilities and manufacturing areas where ventilation is needed. Whether using wind, temperature differences or creating the stack effect, which drives natural airflow caused by thermal conditions, natural ventilation will improve your building’s indoor air quality and energy efficiency. It will also reduce the need for expensive mechanical ventilation systems.
