CSR’s Triniti III Building, situated in Stockland’s North Ryde A-grade Office campus, is a six-storey, 9,000 sqm building which has brought together 360 CSR staff from multiple CSR operations into one location.
The project was a collaboration between CSR and three primary parties - property owners Stockland, architects Morris Bray and builders Baulderstone.
Architect Cameron Martin of Morris Bray says: "The intention was to create a bright, comfortable and pleasing space that took advantage of natural light and encouraged a collaborative culture among the staff working across different brands."
From the outside of the Triniti Building, the blue-toned glass - Viridian’s EVantage SuperBlue with a vertical glaze - creates a unique visual appearance within the office campus and harnesses good light transmission.
Performance of the glass was enhanced by using it in the Viridian ThermoTech Double Low E insulating glass units. This minimises variations in office temperature due to good U Values and SHGC values.
CSR registered for a Green Star Office Interiors rating, aiming for a 5 star Green Star rating. Rob Ferrari, commercial segment manager, completed the GSAP course and exam and joined the Green Star design team to assist with the use of materials and determine which ones could contribute to points in the Green Star rating tool.
Colliers were engaged for the interior design of the Triniti building. The brief for Colliers included the requirement for the interior design to meet Green Star standards and the integration of a range of CSR products.
The floorplates, orientated in an east-west direction, minimise early morning and afternoon heat loads while allowing maximum natural light into all office spaces.
The use of glass for the staircase creates a decorative feature and diminishes the need for a lift. The stairwell also has Cemintel’s new BareStone 9 mm compressed fibre cement lining panels, with 50 customised, perforated units with an acoustic back feature.
Providing the backdrop to this workplace is 5,000 metres of Gyprock EC08 plasterboard, a fire-grade board with high acoustic properties and the first Australian-made plasterboard to be certified by Good Environmental Choice Australia (GECA). This reduced the documentation required to contribute to certification points in the Wall & Partition calculator.
Bradford Insulation specified 2,800 metres of 75 mm, 14 kg partition batts throughout the partition walls to further improve the acoustics of the building, though the solid R1.8 value of these batts also contributed to improving the building’s energy efficiency.
Hebel is fastened to the Rondo wall grid and when attached to the Gyprock EC08, provides a complete acoustic and environmentally sustainable solution that also meets and exceeds BCA fire grade regulations.
Cemintel Fibre Cement Systems was used in bathrooms and shower areas, while Fricker's 611 tile was used throughout, with specialist areas such as the boardrooms featuring the Fricker System 150 perforated metal ceiling tiles.
Suspended from the Fricker ceiling is the acoustic Ecophon range of products by Fricker. Being used for the first time in Australia, the Ecophon MasterSolo are slim floating panels which are fully encapsulated high-density wool panels which have excellent sound absorption for frequencies above 250 Hz while also providing high absorption for low frequencies.
Bradford Insulation applied the baffleblock installation technique above the top floor ceiling, which places 10-12 of 75 mm, 14 kg insulation batts on top of each other throughout the 2,000 sqm of area to further maximise ceiling acoustic and thermal performance.
