The façade of 1 Bligh Street in Sydney will feature two distinct sets of glass skins. Automated venetian blinds will function between the skins, shielded from the elements.
The outer glazing skin, i.e. the external glass panel exposed to the elements, has been designed to promote airflow through fixed horizontal vents at the top and bottom of each level of the building, thereby preventing excessive heat build-up during summer.
