This month on Facility Management we’re revisiting some of our most popular and inspiring articles and 1 Denison earning a 6-Star NABERS Energy and Waste ratings and WELL V 2 Platinum certification last October is worth re-celebrating. 

Winten Property Group’s 1 Denison commercial office tower has bolstered its sustainability ratings, achieving 6-Star NABERS Energy and Waste ratings and WELL V 2 Platinum certification.

Designed by architects Bates Smart, 1 Denison was delivered by Multiplex in 2020. It features 61,600 square metres of commercial office space across 37 storeys, with a lifestyle precinct and basement parking for 225 cars, which features 568 bicycle racks.

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

Energy efficiency measures

The building’s NABERS 6-Star Energy rating was elevated through a commitment to energy efficiency. Since its completion, the total energy consumption at 1 Denison has been more than halved annually, from 3.8 gigawatts (GW) in 2020 to just 1.6GW in 2023.

1 Denison’s energy efficiency was further increased through a range of initiatives implemented by its property management team 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 percent less energy being used for the chiller alone. Peak load lopping is also used. This reduces the amount of energy consumed during periods of peak demand and further optimises the building’s electricity usage.

Waste management strategies

1 Denison attained a 6-Star NABERS Waste rating through a focus on waste management strategies. It aims to achieve 100 percent landfill diversion and a zero-landfill target.

“We are proud to be recognised as North Sydney’s most sustainable office tower,” says Stuart Vaughan, COO of Winten Property Group.

“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 ESG (Environmental, Social and Governance) targets – it also reduces building outgoings and expenses for our tenants.”

Achieving the highest WELL certification

The building was also awarded a WELL Platinum V2 certification, which recognises 1 Denison’s excellence across a range of factors including air, water, nourishment, light, movement, thermal comfort, sound, materials, mind and community.

“We are proud to achieve the highest WELL certification available, with this sought-after global credential only granted to an elite selection of premium commercial buildings across Australia,” says Jay O’Neill, associate director of facilities management at 1 Denison.

In November 2021, 1 Denison was also certified by the Green Building Council of Australia with a 5-Star Green Star rating.

A focus on tenant wellness

1 Denison demonstrates a commitment to the health and well-being of its tenants through a range of features, including its purpose-built wellness amenity, end-of-trip facilities, circadian lighting, bi-annual ergonomic assessments, water and air quality testing, stress support program, healthy food options and retailers, and annual on-site flu vaccinations.

The building also contains an in-house wellness centre, Nest, which is located on Level 23. The expansive size and location of the tenant-focused wellness centre on the building’s high rise rather than ground plane make it unique.

O’Neill says Nest is “a major point of difference”, which is being “swiftly embraced by tenants, making it easy for them to incorporate balance and well-being into their everyday work life”.

The 300-square-metre holistic wellness amenity accommodates a range of health and wellness activities, including circuit training, yoga classes, boxing, massage, flu vaccinations, skin consultations, chiropractic and a pilates reformer studio.

Nest’s visitors are given access to an exclusive restorative lounge plus an array of end-of-trip features, including complimentary fresh towel service, Dyson hairdryers and GHD hair straighteners, ironing facilities and drying cupboards.

Sustainability features at 1 Denison

The landmark tower boasts a range of innovative sustainability features, including on-site 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 productivity and energy as well as healthier sleep patterns.

1 Denison provides tenants with a waterless, eco-friendly car 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.
