In seeking solutions, a study by Lewis Turner found that, while air purification systems reduce infection risk, they should only be used when mechanical ventilation is not available. Tim Dwyer reports

It’s a breeze being cool in class

Overheated indoor spaces in tropical regions pose challenges for building occupants, particularly in areas with limited access to air conditioning. A study by Dr Charles Munonye evaluates the thermal comfort of Nigerian schoolchildren in two building types to see if cooling is needed in primary schools

Targeting net zero ventilation for schools

The Monodraught HVR Zero ventilation unit won a product of the year award at the CIBSE Building Performance Awards because it targets both embodied and operational energy use. Schools are one sector benefiting from the costs savings that the heat recovery unit brings
