The main requirement for air conditioning was on the ground, first floor and basement archive stores. All plant was estimated to have been installed during the past three decades, and for the first 15 to 20 years the plant underwent refurbishment once. Planned preventative maintenance (PPM) was introduced by the facilities management team , which realised that further improvements could also be achieved. Following an air conditioning inspection, the report
