Looking at benchmark projects across the country, the Australian Smart Skyscrapers Summit 2017 will examine the ways in which Australian high-rise building design and construction continues to adopt new technologies, innovations and features.
Sydney’s 1 Bligh Street is a case study in environmentally friendly design and construction, incorporating features such as a double skin façade, naturally ventilated atrium, 40% recycled concrete, 90% steel with 50% recycled content – FSC certified timber, recycled timber, solar cooling, tri-generation, black water treatment, rainwater harvesting and sewer mining.
Managing Director at Architectus, Ray Brown describes the design for 1 Bligh Street which incorporates an innovative tri-generation system that utilises gas and solar energy to generate cooling, heating and electricity. Likewise, a hybrid cogeneration system uses gas to generate energy or can use an array of 500 m2 of roof mounted evacuated tube solar panels that provide solar energy to directly power the absorption chiller.
According to Brown, another overlooked feature are the fire stairs located at the perimeter of the core, “designed to encourage inter-floor connectivity and enjoy city views to the south and an abundance of natural light”. Moreover, “bathrooms at every level also enjoy natural light and views making the most private of spaces attractive and functional”.
However, 1 Bligh’s standout feature, says Brown, “is undoubtedly the fully glazed double-skin facade specifically developed to optimize amenity for occupants”. Designed to facilitate continuous perimeter offices amongst other fit-out options, without the complication of external columns which block views, the façade structure creates a high degree of equitable floorspace.
The 130 metre, naturally ventilated glass atrium running the full height of the building, introduces a rare level of natural illumination and ventilation throughout the building. Brown says that the atrium “brings a diversity of space to the workplace previously not seen before in a high-rise office building in Sydney”. This diversity comprises break-out spaces, meeting pods and bridges that enjoy access to fresh air and natural light at every level.
In terms of sustainability, the breakout spaces located on the south side of the atrium are designed to achieve year round comfort without the use of additional energy for heating or cooling the spaces. Rather, the breakout spaces are naturally ventilated through a series of automated glass louvres. Free heating is provided by in-slab pipework supplied by the heat that is normally rejected via the cooling towers, and spaces are cooled on hot days by the relief air from the main office spaces. The entire lobby is natural ventilated using in-slab heating and relief air cooling to temper conditions during very cold and warm days.
Projects such as Australia 108, soon to be the tallest skyscraper in Australia, 323 La Trobe Street, Australia’s tallest prefabricated building, One Central Park, which houses the world’s tallest vertical garden and 1 Bligh Street which has won awards for its sustainable features, including the six-star green status by the Green Building Council of Australia will all be profiled at this immersive two-day event.
The Australian Smart Skyscrapers Summit 2017 will be held at the Melbourne Convention and Exhibition Centre on the 28th and 29th of March.
