The refurbishment works in 2017 included for the relocation of the air conditioning plant from the roof to facilitate future maintenance but did not include for any additional air conditioning within the building.

The contact room, now more heavily populated than before by the Call Centre staff, has no mechanical ventilation and limited heating and opening windows to improve ventilation in the colder months will require supplementary heating to achieve a suitable working environment. The proposed air-conditioning will heat/cool the room and help re-circulate the fresh air.
