Understanding the environmental impact of commercial office buildings, particularly when built from scratch, Quintessential Equity embarked on the revitalisation of 2–6 Bowes Street, Phillip, to significantly reduce its carbon footprint and waste, and achieve a target 5-Star NABERS Energy rating.

Measures such as bicycle parking, energy-efficient plant and equipment, building insulation and occupancy sensors were paired with a sleek, modern design.

Further enhancements as a result now ensure building occupants can make use of the nearby public transport systems and are also encouraged to walk and cycle to work with the new modern bathroom and other end-of-trip facilities, all contributing to further emissions reductions for the building.

Contractor Energy Action developed a computer simulation model of the building fabric, complete with its operational performance. This was used to ensure the service upgrade was best suited to both the day-to-day temperatures and the extremes of Canberra’s climatic conditions, as well as accounting for building orientation and solar loads.
