In particular:All buildings in this sample had cooling towers. This is fairly typical for largerbuildings in Sydney and indeed much of Australia.Amenities water consumption averaged 0.5 kl/m². The wide variance in this figurereflects the potential for poor performance of amenities water consumption due topoorly operating urinals, high flush volume toilets and, to some extent, leakageflows that were not separated into the leakage category.176
