Winten Property Group’s $1.2 billion 1 Denison commercial office tower said it has achieved WELL V 2 Platinum certification and 6-star NABERS Energy and Waste ratings, positioning it North Sydney’s most sustainable commercial office tower.

Designed by  Bates Smart, 1 Denison features 61,600 sqm of premium grade commercial office space across 37 storeys, with an innovative lifestyle precinct and basement parking for 225 cars and 568 bicycle racks.

WELL V 2 Platinum Certification is the highest possible rating and recognises its wellness amenities and facilities, enabling occupants to maintain their physical health, productivity, social connections, and happiness in the workplace.

1 Denison has also been awarded a 6-Star NABERS Energy rating and, most recently, a 6-Star NABERS Waste certification as well.

“We are proud to be recognised as North Sydney’s most sustainable office tower. Our sustainability objectives are closely aligned with those of our tenants. Delivering a high-performance building not only improves our environment and assists in meeting tenant Environmental, Social & Governance targets – it also reduces building outgoings and expenses for our tenants,” said Stuart Vaughan, Chief Operating Officer of Winten Property Group.

According to 1 Denison’s Property Managers CBRE, the high-performance building’s sustainability was further enhanced through strategic, operational fine-tuning road-mapped after the building was constructed.

“We identified several core environmental pillars to focus on including reducing energy and waste, with occupant health and well-being also paramount. We collaborated with our project team and developed strategic pathways to achieve these new environmental benchmarks,” said Nathan Chehab, General Manager of 1 Denison Street.

Since its completion, the total energy consumption at 1 Denison has been more than halved annually, from 3.8 MW in 2020 to just 1.6MW in 2023, successfully elevating the building’s NABERS rating.

1 Denison’s energy efficiency was further increased through a range of initiatives in collaboration with Conservia, the Building Management System vendor, providing an energy management platform under a preventative maintenance structure.

Initiatives used to enhance environmental performance included optimising Tenant Condenser Water and Chiller Staging modification to maximise efficiency and reduce peak demand during summer, effectively resulting in 20% less energy being used for the Chiller alone. Peak load lopping is also utilised, reducing the amount of energy consumed during periods of peak demand and further optimising the building’s electricity usage.

In addition, a focus on waste management strategies at 1 Denison aims to achieve 100% landfill diversion and a zero-landfill target.

Among its sustainability features are onsite rainwater harvesting which delivers 70,000 litres of water to the building’s amenities. 1 Denison’s windows feature high-performance glazing and automated blinds to reduce the impact of harsh sunlight on its tenants, while energy-efficient lighting is tuned to occupants’ Circadian rhythms, which fosters both greater productivity and energy as well as healthier sleep patterns.

1 Denison provides tenants with a waterless, eco-friendly car wash by Wow Wash, which saves an average of 200 litres of water per car. Tenants are also given the opportunity to lease low-emissions vehicles via their digital building app, with access to Tesla car and Lekka bike hires, in partnership with Ohmie Go.

The building is fully leased and is home to several high-profile corporate tenants from a diverse range of industries, from media and technology to fashion and medical. Tenants include Nine, Microsoft, SAP, Qualtrics, Red Hat, Essilor Luxottica, Indue, Datacom, Galderma, Qualitas Health, Ferrovial and Spaces.

The food and beverage precinct at 1 Denison is also fully leased with a selection of venues, from restaurants to cafes and takeaway outlets serving fast eats. Tenants include BarLume, Poetica, Missing Spoon, SixNature Thai, Stacked, Cali Press, Well Foods Kitchen, Lumos and coming soon, Bourke Street Bakery.
