Considered Sydney’s third CBD, Liverpool, in the rapidly growing greater south west region, is undergoing a significant transformation. The completion of a new 4 star Green Star commercial office building is representative of this change as the city welcomes new business to the area.

Located just 150m from Liverpool Station, 25-35 Scott Street was designed by Group GSA architects and built by Taylor Construction for owner Goldstein & Rush Pty Ltd.

The 15-storey office tower includes ten commercial office floors with over 10,000m² of flexible office space offering natural light through floor-to-ceiling glazing. The building also features four basement car parking levels, a rooftop garden terrace and a ground floor café.

The project has been certified by the Green Building Council of Australia (GBCA) with 4 star Green Star Design and As Built ratings. It has also received a 4.5 star NABERS Energy rating.

Taking over a mechanical services design by JHA Consulting Engineers, ICR Air Conditioning were engaged by Taylor in a design and construct (D&C) role. The Sydney-based mechanical services contractor provided air conditioning to all office levels, as well as car park ventilation and general ventilation to amenities, store rooms, switchboards and communications rooms.

To help meet the project’s Green Star and energy efficiency objectives, ICR has installed approximately 360 Rickard Linear VAV diffusers across office levels one to nine. Supplied by Fantech, these units were selected over a traditional VAV box design due to their energy efficiency, ability to provide superior thermal comfort and ease of rezoning.

“Creating zones for fitouts can be done relatively easy with an additional thermostat and programming,” says ICR project engineer, Luke Anderson. Anderson says the Rickard VAV diffusers also provide for a more reliable terminal velocity with the turndown of air. “The air throw is more constant due to the adjustable plate at the VAV diffuser,” he says. “This prevents the dumping of air at lower airflows when the system turns down.”

Maintenance is also made easier due to the units’ localised controls. “Local access rather than via the BMS (building management system) is handy for maintenance, minor adjustments and fine tuning,” Anderson says.

Having not used the Rickard Linear VAV diffusers on a project of this scale before, ICR worked closely with Fantech, the diffuser manufacturer and the control company to determine the best control strategy for the building.

Fantech also supplied fans to meet the ventilation and exhaust air requirements of the kitchen and toilets, fire pump room, basement level car park and general exhaust. Fantech products were also used in the outside air supply and stairwell pressurisation systems.

“ICR has had a good working relationship with Fantech for as long as I have been working with the company,” Anderson says. “The majority of our engineers and project managers, including myself, have also attended the Fantech training programs. We trust the performance of the products and the data Fantech supply, and we often utilise the Fans by Fantech selection program to assist with our design process.”

25-35 Scott Street Liverpool reached practical completion in December 2018.
