Found this interesting rundown in Wikipedia -
just to confuse the matter further....
These are examples of above-ground mechanical floor layouts for some of the world's tallest buildings. In each case, mechanical penthouses and spires are counted as floors, leading to higher total floor counts than usual.
Taipei 101: Floors 7–8, 17–18, 25–26, 34, 42, 50, 58, 66, 74, 82, 87, 90–91, and 102 in the penthouse (total 17/102, or 17%). The official count of 11 corresponds to the number of groups in the office section. Floors 92–100 contain "communications equipment"and so are not typically counted as mechanical since they do not service the building itself.
World Trade Center Twin Towers: Floors 7–8, 41–42, 75–76, and 108–109 (total 8/110, 7%).
The 110th Floor of 1 WTC (North Tower) housed television and radio transmission equipment. Some sources erroneously mention 12 floors, in groups of 3, due to the height of the vents (actually the ceilings there were higher) and because levels 44 and 78 were skylobbies which in many buildings sit directly on top of the mechanical floors. However the twin towers had one occupied office floor under each skylobby, accessible through escalators.
Willis Tower: Levels 30–31, 48–49, 64–65, 104–108, and 109–110 in the penthouse (total 13/110, 12%).
Petronas Towers: Floors 2–7, 38–40, 43, 84, 87–88 (total 13/88, 15%) (New York Times, Elevator World magazine)
Jin Mao Building: Floors 51–52, and 89–93 in the penthouse (total 7/93, 7.5%) (SkyscraperPage)
Burj Khalifa: Floors 17–18, 40–42, 73–75, 109–112, 136–138, 155, and 160–168 in the penthouse (total 25/168, 15%)"
