Metro Tunnel project –O v e r v i e w –
From the completion of the City Loop 30 years before, Melbourne Metro Tunnel is the major investment in the CBD rail facility. With a new end-to-end Sunshine-Dandenong line and proposed underground stations, the Metro Tunnel Project built two 9 km rail tunnels from Kensington to the South Yarra area. The five proposed underground stations are as follow: •
North Melbourne (Arden)
•
Parkville
•
State Library
•
Town Hall
•
Anzac (Domain)
The Sustainability Targets are focused on global benchmarking and consistent with quality standards with special emphasis on train networks and the highly up-to-date tools in the sector of sustainability rating.
State Library Station
-O v er v i e wState Library Station will be situated mainly below Swanston Street and connected to the central station of Melbourne. The two primary entrant points will be: at Franklin Street and at the north-west point of Swanston and La Trobe streets. Emergency accessibility and ventilation facilities will also be available on the street. The area includes important institutions and services, such as the RMIT University, Melbourne Central Station, State Library, shopping center and Melbourne City Baths. The north of the city is rapidly changing and developing more intensively. Several major residential towers have been built or approved recently. The Carlton United Breweries site is being redeveloped north of Victoria Street.
RMIT Renewable project In the west of Swanston Street, the RMIT campus continues to expand with a major proposed development (Renewal Project) on a site at A'Beckett Street. The Station increases public transit connectivity to this area of the city, encourages the efficient use of land directly and enables enough road space to be utilized, notably for walking and cycling, for sustainable transport approaches. The design criteria for RE project further incorporates the following: • • • • •
The area of the site (RE project) should not be greater than 50 m2. A predicted output will be 9 MWh/y from renewable energy sources. Includes an aspect of community education. Must comply to the goals of CYP D&C Urban Design. Must be safe to engage with the public with budget under $50,000
On average, the site has received strong thermal energy at about 4.5 kWh/m2 a day (BOM, 2021), on average yearround and is subjected to average wind speeds of 6 km/h, during summers are presented in the findings of the preliminary site. Thus, solar and wind resources may be considered for the RE design. In contrast, analysis found that pedestrian and vehicle traffic flow will be able to provide a high level of useable energy for local use. Later, four criteria have been defined to satisfy the sustainability goals of the client's demand, and different evaluation approaches are being suggested. Based on the RE project configuration, appropriate assessment selection will be made.
Annual wind speed (km/hr)
Annual Global exposure (MJ/sqm)
Annual mean minimum temperature (◦C) Annual mean maximum temperature (◦C)
Annual rainfall (mm)
Site Analysis Conclusion
Design Proposal The committed area proposed for the renewable energy designed is 40 sq m. The concept for the proposal is evolved from the renewable sculptures where books sculpture is designed to depict the symbolic representation for the State Library Station. The aesthetically pleasing and engaging design includes the coating with photovoltaic thin film and tiny spherical balls of 1.2mm to 1.8 mm in diameter which have electrodes on opposite sides. These tiny silicone balls are woven in the bird's shape and rotates on its axis resulting in generation of energy by solar and wind moving these balls.
