KAE in association with BLL and DJRD Architects undertook the Mechanical Services design for major shopping centre at Penrith, NSW.
The shopping centre expansion includes for a multi storey shopping centre with typical tenancies fronting onto an open street. In addition the centre includes for major stores, food courts, loading dock, food tenancies, amenities etc.
The centre is atop a 364 car underground car park. KAE undertook a Computational Fluid Dynamics (CFD) analysis to enable an engineered design solution deleting significant riser and ductwork requirements. The design allows for a virtually ductwork free car park.
The mechanical plant comprises central chilled water cooling plant (chillers, towers etc) serving distributed air handling units. Significant energy saving measures have been incorporated into the design.
The main project design requirement was for low energy consumption. The design allows for the following energy saving initiatives:
- Efficient central plant systems
- Variable volume primary only chilled water circuit
- Variable air volume air handling plant
- CO detection within the car park to control the car park fan speed
- CO2 detection within centre air handling plant to control the fan speed
- Free cooling via façade openings and mixed mode operation
- Economy cycle controls
- Fabric selection and performance
- Low resistance system design
