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

LSBU’s cool new hub

More than half of all UK building services engineers studied at London South Bank University, so BDP’s services retrofit of the main building on the campus had to demonstrate best practice in every function.
