中庭是独特的室内公众空间,他与开放的广场构成了互补关系。它有两个独特构件(南部中庭和北部中庭),由连接广场与NGV的穿越式纵横隔开。作为持续的公众空间,中庭体现了广场连接城市于雅拉河的本意。
中庭中闪亮的开放式结构框由广场立面所体现的同样几何概念演化,并加以变形为立体系统。此系统的进深起导热功效,疏散上升的热气流;中庭配有被动式制冷系统,在夏日可使室内温度保持12度低于室外温度。
北部中庭为市民聚集所用,其宽阔空间可以包含现场音乐表演,马戏节目,合唱及演讲等室内活动;中庭已成为市场营销,都市节目,时尚秀,展示,晚宴等活动的常规场所。

the atrium is a unique covered public space which provides a complement to the open plaza. it is formed into two distinct elements, (designated north and south) by the lateral insertion of the x-bar which acts to link the plaza to the NGV galleries, and the city beyond. as a continuously open, publicly accessible space, the atrium is emblematic of federation square’s intended connection of city and river.
the north atrium, as a glazed covered street, provides a forecourt to the gallery building through an open interior volume 16 metres high and up to 20 metres across. this glass enclosed galleria is animated on one side by the NGV’s bookshop, cafe and restaurant facilities, and on the other by additional retail and commercial outlets.
the south atrium steps from the deck level over the railway down to the river side promenade. within this transition, an amphitheatre has been formed, providing a public theatre for incidental daily events, casual performances or ticketed performances during festivals.
the design has been acoustically tuned to provide a space suitable for small to medium sized music and theatre ensembles.the open galvanised structural frames of the atrium evolved from the same triangular geometry as that of the facades, but developed as a folded three-dimensional system glazed both inside and out.
the deep space of this supporting frame acts as a thermal chimney, evacuating the build-up of hot air. the atrium space itself is conditioned by a passive-cooling system, using a low-level air displacement system to keep the comfort zone of the atrium up to 12? C cooler than the outside temperature in summer.
