FRESH air and effective ventilation are one of the most important aspects of classroom design.
Proper ventilation is not only critical in maintaining air quality, it is essential for compliance. The issue of ventilation was highlighted during the pandemic with an increased focus on air circulation and bringing fresh air into rooms - in an effort to reduce the risk of spreading the virus. But ensuring adequate air flow in a closed space has always been an essential part of service delivery and design.
In Queensland, where mean summer temperatures can soar to above 40 degrees celcius, it’s not difficult to recognise the value of air-conditioning to keep spaces cool. What may be less obvious however is an additional factor that isn’t as obvious is the need to ventilate to prevent the build up of Carbon Dioxide (CO2).
Carbon Dioxide is produced as a waste product of respiration, a normal result of breathing. The more people in a room, the more carbon dioxide is produced. Schools typically have a relatively high occupancy density, meaning many students in relatively small classroom areas.
This means ventilation design and outside air intake are critical to maintaining indoor air quality while aligning with the National Construction Code and relevant Australian standards including AS 1688 where applicable.
- Fresh are reduces C)2 build up improves alertness and supports a healthier indoor environment
- Poor ventilation leads to comfort complaints, fatigue and potential compliance risks
- In school environments outside air design is not option, it is fundamental
