Winner

The Ausgrid Technical Learning Centre is a new construction that brings together scattered facilities into one integrated modern campus style learning facility. The project achieved a 6 Star Green Star Design Rating and is currently being assessed for 6 Star Green Star As Built.
The Centre has installed 51 kW of photovoltaic cells for electricity generation, along with a Tri-generation unit using Natural Gas in an engine to run a generator for electricity, with the engine cooling water used for heating and an absorption chiller for cooling. 
There are 55 Geothermal bores each 100 metres deep which are used for heat rejection from the building. Variable Air Volume air-conditioning with high induction swirl diffusers are used for the rooms and Offices. The building also uses a combination of mechanical cooling and heating systems, natural ventilation, mechanical ventilation, ground source heat rejection, and the thermal plants for chilled and heating water circulation.
Rain Water is stored in a 150,000 litre rain tank for toilet flushing and irrigation. Used shower water is collected and 2,200 litre/day is then treated using a bio filter and UV, which is also used for toilet flushing and irrigation. 
96.45% by mass of construction waste was recycled, with less than 4% going to landfill. Carpets, paints and sealants were chosen for their Low VOC and used to improve occupant health, all timber was FSC approved, and the concrete is Green mix utilizing a high recycled content.
The Centre is located close to public transport. The parking area for Staff, Students and Visitors uses a high level of natural ventilation and provides 31 dedicated small car spaces, 10 electric car parking/charging spaces, 35 motorcycle parking spaces, car pool spaces, and bicycle racks.
Separate metering of power and lighting is used to identify high use areas. Lighting control use local isolating switches, occupancy sensors, time switch controls and daylight controls, and operate through the Building Maintenance Control System (MBCS).
The building emits about 37% of the CO2 compared with a similar building, supporting the Excellence in Energy Efficiency Award
