1. A door arrangement for use within a data centre building, wherein the door arrangement is arranged to be fitted within a wall space,the door arrangement includes a door allowing human access therethrough,the door arrangement comprises a controllable air intake arranged such that the flow of air through the door, when in its closed position, is controllable by means of the controllable air intakethe door arrangement comprises at least one motor for moving the controllable air intake between an open position, thus allowing air to pass via the air intake, and a closed position,the door arrangement is arranged to receive a control signal for controlling the operation of the motor, and wherein in moving the controllable air intake the motor sets the position of the controllable air intake to actively regulate the airflow through the door between three or more airflow levels. 2. A door arrangement according to claim 1, wherein the air intake is arranged to move so as to enlarge or reduce the effective cross-sectional area of one or more apertures. 3. A door arrangement according to claim 1, wherein the controllable air intake is controllable by moving the door. 4. A door arrangement according to claim 1, wherein the door is movable, whilst still closed, to vary the flow of air. 5. A door arrangement according to claim 1, wherein the door and the air-intake are separate. 6. A door arrangement according to claim 1, wherein the door comprises the air intake. 7. A door arrangement according to claim 1, wherein the controllable air intake is in the form of a vent within the door shaped such that the vent extends across more than 50% of the width of the door and across more than 50% of the height of the door. 8. A door arrangement according to claim 1, wherein the controllable air intake comprises a plurality of blades all arranged to rotate about parallel axes. 9. A door arrangement according to claim 8, wherein the axes are vertical axes. 10. A door arrangement according to claim 8, wherein the blades comprise at least one pair of adjacent blades that are arranged to rotate simultaneously in opposite directions. 11. A door arrangement according to claim 8, wherein the controllable air intake is in the form of a vent and wherein the blades are arranged to rotate together to effect control of the flow of air through the vent. 12. A door arrangement according to claim 8, wherein there are two or more motors to move the blades. 13. A door arrangement according to claim 8, wherein there are six or more blades. 14. A door arrangement according to claim 8, wherein the blades extend across more than 50% of the width of the door. 15. A door arrangement according to claim 8, wherein the blades extend across more than 50% of the height of the door. 16. A door arrangement according to claim 8, wherein the controllable air intake is in the form of a vent and wherein the effective open area when the vent is open is greater than 1 m2. 17. A door arrangement according to claim 8, wherein the controllable air intake is in the form of a vent and wherein the vent is arranged such that in the event of a failure the vent would fail open. 18. A door arrangement according to claim 1, wherein the level of adjustment possible is substantially continuous as between a fully closed and a fully open position. 19. A door arrangement according to claim 1, wherein the door arrangement is arranged to be fitted within a wall space and the door is movable relative to the wall when the door is in its closed position to allow the air intake to scoop varying amounts of air from an air supply corridor. 20. A data centre building comprising a door arrangement, wherein the door arrangement is arranged to be fitted within a wall space,the door arrangement includes a door allowing human access therethrough,the door arrangement comprises a controllable air intake arranged such that the flow of air through the door, when in its closed position, is controllable by means of the controllable air intakethe door arrangement comprises at least one motor for moving the controllable air intake between an open position thus allowing air to pass via the air intake and a closed position,the door arrangement is arranged to receive a control signal for controlling the operation of the motor,wherein in moving the controllable air intake the motor sets the position of the controllable air intake to actively regulate the airflow through the door between three or more airflow levels, andwherein the data centre building includes a rack room and the data centre building is so arranged that there is at least one aisle in the rack room, the aisle being adjacent to a rack storage area, said at least one aisle including a doorway to the aisle, the doorway comprising the door arrangement, wherein the building is so arranged that, in normal use, cooling air flows via said doorway into or from the aisle when the door is closed. 21. A data centre building according to claim 20, wherein the door arrangement includes a door movable between a closed position, closing the doorway, and an open position, allowing personnel access to the aisle. 22. A data centre building according to claim 20, wherein the air intake and/or door is arranged to move so as to scoop more or less air from an airflow. 23. A data centre building according to claim 20, wherein the door arrangement is located on the end of a cold aisle. 24. A data centre building according to claim 20, wherein the door arrangement is located on the end of a hot aisle.
