The Commonwealth Bank of Australia has signed on as a major tenant of Daisho Group’s 180 Brisbane building, the first building in the state to achieve a 6 Star Green Star Design v3 rating.

Knight Frank and Colliers International brokered the leasing deal, which will see CBA occupying 10,500 square metres over six floors on an average 11-year term and also hold sky signage rights for the 34-storey tower, due for completion near the end of 2015.

Designed by Crone Partners and constructed by Watpac, on completion the $210 million project will comprise 59,100 square metres of A Grade commercial space with podium and ground floor retail and basement parking. A public plaza with green wall elements integrates the ground plane with the neighbouring Daisho-owned 192 Ann St, which was constructed by Watpac in 2000.

Daisho Group manager Yasuo Iwasaki said the project’s environmental credentials were a major part of its market appeal.

“We’re excited to announce that our first leasing deal for 180 Brisbane is to such a leading Australian company. It’s a strong endorsement of the building’s design and its ability to deliver central, contemporary and environmentally sustainable commercial space,” Mr Iwasaki said.

“Daisho is committed to delivering exceptional commercial space with high environmentally sustainable features.”

CBA will be encouraged to embrace sustainability in terms of its behaviour as a tenant, Daisho Group property manager Kirk Muddle said.

“While not an absolute requirement, we strongly advise and encourage all of our current and potential tenants to follow the precedent set by the base building sustainability initiatives,” Mr Muddle told The Fifth Estate.

He said CBA were working towards targeting a Green Star Interiors rating.

Energy innovations and a smooth transition to long-term occupancy

The development has been project managed by Savills. Project director Dean Miller said the building incorporated a range of intelligent building systems, as well as low-carbon energy initiatives including a one megawatt gas powered trigeneration system, 100 kilowatt roof-mounted solar power generation system, solar heating and grey water recycling. The base building has earned a 5.5 star NABERS rating.

“In addition to these intelligent systems, the building will be constructed from high performance building materials and include premium quality end-of-trip facilities for occupants and building users who choose to walk, run or cycle to and from work,” Mr Miller said.

“The lobby will also include a display of real time train and bus arrival times for public transport nodes in close proximity to the building, helping tenants get to where they need to be quicker and more efficiently.”

This initiative earned the project two innovation points under the Green Building Council of Australia rating tool.

A high-level visual interface will also be provided in the lobby to show energy, water and natural resource use for the building. Mr Miller said tenants would be able to collect and convert data from the base building management system for their individual tenancy, including energy use and occupancy control.

Floth are principal engineers for the development. Floth partner, principal electrical engineer and ESD professional Ian Osborne told The Fifth Estate that monitoring and managing energy use, both for the base building and for individual tenants, would be facilitated through a range of technological innovations.

“Each tenancy switchboard has separate metering for lighting and power to assist tenants to monitor their energy use,” Mr Osborne said.

Tenant light fittings are individually addressable and dimmable, which Mr Osborne said would enable tenants to reduce energy use through highly flexible lighting control.

All of the base building’s plant equipment will be individually metered through a dedicated metering system to enable accurate monitoring and management of the building’s energy use. This will also assist the facilities management team to maintain the high energy efficiency of the building plant by providing early warning of excess energy use.

Daisho’s facilities manager was involved from the early design stages to ensure “maintainability”, and this earned the project a further Innovation point.

Another point was gained through plans to assist the FM team in familiarising themselves with the operation, maintenance and ongoing servicing of the various building systems, through building into the construction contract a requirement that the original building services installers maintain the systems and work with the FM staff for a period of time post-delivery.

Green tactics for operational waste

Waste management during the building’s operational life has also been a focus.

“The building will incorporate a dedicated waste streams management system with a focus on recycling initiatives. We are currently investigating the introduction of a mechanical compactor to assist with the management and transport of waste,” Mr Miller said.

Mr Muddle said the building’s co-mingled recycling system will allow users to “take responsibility for their recycling and monitor how much general waste is being produced”.

As of January 2015, about 70 per cent of the structure and 60 per cent of the entire project scope had been completed, with a new level being constructed every six working days.

Mr Iwasaki said the development represented a significant investment by Daisho and reflected the confidence the company has in Brisbane’s economic outlook.
