The evidence- and research-based design incorporates carbonreducing t«hnologirs and water capture methods to meet the strong sustainability targets set.

Central to the functioning of the hospital and to the sustain· ability of the design is a clever wayfinding device: the street (figure)), Based on the idea that CYen the smallt$t country town has its amenities grouped around a central street, this -allows visitOt$ and staff an intuitive unden:tanding of where they arc in the hospital In this model, a large building becomes a community ofbuildings-an institutional building becomts deins-titutionalised. and each of the parts acquire$ independent character. The street conctpt, which conn«ts tht campus, is extendable and adapt· able. It allows for futurt organic growth or extra •address points.. to be added along the s1ree1. The site has a natural, diagonal fall from cast to west, which
means the north-facing street created three levels of gardens around the buildings (figure 4). The entire north-facing wall of the street is glass -and provides a lovely vista onto the Grtat Garden Court, the largest ofthe sheltered gardens S\ltrounding the hospital. Louvrts high in the atrium allow natural \'Cntilation and a thermal labyrinth provides passive heating and cooling for the area. Me-lbourne's skyline and park arc visible along the str«t, this s.crves as a permanent marker for wayfinding -and is complemented by memorable inttrnal devices S\IC.h as a giant aquarium next to the reeeption de.sk. which helps direct people to the Emergency Department.
