It’s important you consider how you ventilate your teaching spaces.
Most New Zealand schools are naturally ventilated, with windows, doors and vents which can be opened and closed. Some have ducted ventilations systems too, which provide air flow to occupied spaces.
How to ventilate classrooms
The fastest and easiest way to ventilate classrooms is by opening the windows, doors, and any vents. It’s good practice to fully open all windows during breaks and after school for as long as possible.
For spaces with mixed mode or any form of mechanical ventilation, ensure that:
- there is as much fresh, outside air flow as possible by running systems for longer periods before and after a space is being used
- adjust any ventilation systems which have recirculation (‘economiser’ circuits) so they run on full fresh air mode, with no recirculation
- change ventilation system air filters frequently to increase the fresh air flow and ensure they are well maintained.
Heat pumps do not provide ventilation – they only heat and cool the air in the room.
If you are using a heat pump remember to open your windows and ensure the filters are clean.
Please contact your property advisor if you need further advice on property matters.
We are currently updating our Designing Quality Learning Spaces (DQLS) – Indoor Air Quality and Thermal Comfort requirements to ensure improved ventilation in the design and operation of school buildings.
