Bligh Office Tower, the super ecological Australian tower

The absolute protagonist of the most advanced designs in the name of green orientation is the Bligh Office Tower, inaugurated in Sydney in September 2011. Even before completion, Bligh Tower had already secured the 2011 Award Asia Pacific Property and the International Australian Architecture Award.

The "eco-sustainable skyscraper"Received official recognition to certify the commitment to a 'sustainable building from an environmental point of view through the Green Star Standard, issued by Green Building Council which rewards buildings with low environmental impact. The tower can boast of an unprecedented record: that of being the first office tower to obtain this certification.


It is a 28-storey building, designed as a vertical building whose source of inspiration in the idea and form is the orientation solar. The peculiarity is given by the presence of an atrium that follows the height of the tower itself: this position allows the rooms to enjoy daylight and enjoy natural ventilation. The atrium is overlooked by glass elevators to which the vertical paths are entrusted.

There is also a spectacular scenographic effect with a large staircase that acts as a watershed between the outside and the inside that houses, among other things, a nursery for mothers who work in the offices of the tower. The Tower has two viewpoints located on the fifteenth and twenty-eighth floors. In the external cladding, a double skin fa├žade was used, consisting of an external shield, designed to intercept the sunrays, and an internal one that creates a cavity of air recirculation from which part of the accumulated heat. Such technology it allows to reduce the temperature of the internal glass of the facade through the flow of air that circulates inside the cavity.


The energy system combines the power generation cooling, heating and electrical (trigeneration) and a vacuum solar tube collector that produces electricity on site. Finally, in the basement there is a small water filtration plant that serves for the purification of waste water produced during the day. Of course, there is also a car park: there are 300 guarded spaces intended only for bicycles.
