Addressing overheating at the London children’s hospital

Installed within the Grade 2 listed part of the children’s hospital in London, the brief from the hospitals facility management consultants MITIE and the requirement of the ThermaCool ceiling tiles was to address the serious overheating issues that were being reported in the consultation rooms. With no mechanical cooling systems in place due to heritage planning restrictions and with very minimal window ventilation due to ground level security risks, consultants were experiencing peak internal temperature gains of between 30 – 35°C despite lower external temperatures.

Using a custom high performance version of the ThermaCool metal ceiling tile with an antimicrobial finish along with trickle ventilation in the window, a significant temperature reduction was achieved and improved the thermal comfort temperature to a more acceptable 25 – 26°C.
