University of New South Wales

This new building located at the University of NSW Kensington Campus consists of two new towers.

Tilley Air Conditioning Pty Limited was the mechanical contractor for this new educational facility.

The building is generally air conditioned from air handling units located in plant rooms on each floor of the office tower and fan coil units located in ceiling voids of teaching areas and other spaces. A central air handling unit on level 3 north west, supplies tempered outside air to the fan coil units in the teaching areas. This AHU also provides heating to the teaching spaces and other spaces. Outside air to fan coil units in other areas is supplied from the courtyard via local air intakes.

Primary Plant and Reticulation

• Central air cooled cooling and heating plant located on tower rooftop.
• Primary low temperature hot water for heating and chilled water is generated using a reverse cycle type air cooled heat pump unit with capacity to generate LTHW or CHW. A separate cooling only chiller and a cooling only chiller with heat recovery feature was also provided.
• The plant location is restricted to a central strip running down the centre of the tower roof, with space provisions for a future chiller should the building occupation alter.
• Offices are serviced by air handling units on a floor by floor basis.
• Exhaust ventilation systems are used to purge heat from the east and west facades on each level.
• Room air is drawn in at the bottom of the internal glazing element and exhausted at the high level, removing solar gains captured by the cavity between the glazing and blinds.
• Air purged up the facade within the cavity and exhausted to atmosphere
