Ingenhoven Architects design a sustainable office enviornment 

In the heart of Sydney´s financial precinct, the 139m tall 1Bligh tower combines leading edge design, technology and sustainability. The building´s compact geometry and a slight rotation open the view to the world famous Harbour Bridge while allowing the placement of a strong corner emphasis. This is combined with the main entrance location to provide a strong address for 1 Bligh in a way that directly responds to its urban context.

The ground floor lobby creates a new hub of activity and interaction making 1 Bligh a natural point of convergence. A large grand staircase and two cafes offer a perfect places to meet or enjoy lunch. A child care facility with an outdoor play area provides a place for young children to enjoy. Change rooms with showers and lockers are provided for active tenants.

Australia's tallest naturally ventilated glass atrium soars the full height of the building, providing a consistent flow of fresh air and a sense of openness on every floor enhancing communication, connection and community. Another special spot is the winter garden with harbour view at level 15 as well as the large roof top terrace at level 28.

The structure delivers consistent large floor plates of up to 1600m² and achieves 92% efficiency NLA to FSA. The elliptical plan is 12% more efficient than a rectangular building in facade to floor area and allows excellent natural light penetration.

1 Bligh is the first high-rise office tower in the southern hemisphere to feature a double-skin glass facade. An outer glass skin protects computer-controlled sun shades, shielding the double glazed curtain wall from the sun, whilst reflecting natural light into the building.

The sustainability strategies were designed to achieve a 6 Star Green Star Certified Rating and 5 Star NABERS Energy Rating. 20% of all aggregate used in concrete is recycled, 41% of all cement required for the structure has been replaced with industrial waste by-products and 90% of the steel used has a recycled content greater than 50%. All timber used is either FSC Certified or re-used from a previous application. 1 Bligh incorporates an innovative tri-generation system that uses gas and solar energy to generate cooling, heating and electricity on site. Waste water from the building and Sydney Water sewer is treated on site for toilet flushing and make up water to the cooling towers. A rainwater tank recycles rainwater for irrigation. As a result of these systems sewage emissions have been reduced by 90%.
