Carbon dioxide monitors will not improve ventilation in schools and colleges | Letter

Carbon dioxide screens can not enhance air flow in faculties (Classrooms in England to get air quality monitors to help combat Covid, 21 August). It’s two months previous the solstice and the nippiness of autumn is just a few weeks away. A classroom CO2 studying won’t cease college students from houses heated to 22C, dropped off in summer time garments on the faculty gate from a heated automobile, asking for home windows to be closed or the heating to be turned up.

To scale back gasoline payments and CO2 emissions in schools and faculties, blocking up draughts was an inexpensive first transfer. This usually left the opening of home windows and doorways as the one mode of air flow.

We want a large programme to offer schools and faculties with protected, financial air flow, utilizing cross-flow warmth exchanger techniques, for instance, which warmth incoming contemporary air by way of the nice and cozy extracted air. Academic buildings that depend on forced-air heating and air flow ought to urgently examine that they aren’t incorporating recirculated air, except their techniques adequately sterilise Covid viruses within the returning air.
