420 George Street is a landmark office tower within Sydney’s CBD, providing approximately 37,750 m² of commercial office space over 28 levels. The building also has additional retail tenancies from the basement 1 level through to level 3, which connect to the MidCity Shopping Centre and Pitt Street Mall.
The building achieved a 5 Star Green Star (v2) design rating and NABERS 4.5 Star rating. It incorporates a number of sustainability strategies within the building services, including a hybrid active chilled beam and low temperature VAV air conditioning system, rainwater harvesting, fire system test water recovery, and high efficiency lighting.
NDY was engaged as the Independent Commissioning Agent (ICA) for this project aligned to the Green Star credit. Our role also included an extended comprehensive remit over all building services.
Our scope was further expanded during construction to include overseeing the commissioning of critical services provided for a major tenant fitout. Within this role our team managed and documented the testing and commissioning of the critical service infrastructure, including standby power generation, uninterruptible power supplies and automatic power switching, along with critical cooling equipment. The commissioning exercise included both performance testing and the robust testing of equipment redundancy.
Further, during the building tuning phase NDY provided assistance and feedback accordingly as part of an ongoing involvement in the building tuning 12 month period.
