The winning 2018 LAGI Melbourne public art proposals

Project description: “‘Light Up’ is a lightweight tensile structure and urban planning scheme that captures energy from 8,600 efficient, flexible solar photovoltaic panels that create light-filtered shade over Jacka Boulevard. Additional energy is harnessed when the undulating structure waves in the wind and from the roots of plants with microbial fuel cells.

NH Architecture principal Dean Boothroyd says they sought to honor St Kilda’s longstanding creative tradition. They also wanted to ‘maximize the public realm’ without disturbing views. Team leader Martin Heide says that creating a buildable design with a high return on investment was central to their approach: ‘We used components that are on the market, that are tested, and which connect in a way that makes the design feasible’. He added that the team was particularly excited to join a project that enjoys such robust support from various stakeholders—including the local community, City of Port Phillip Council, and the State.”

Second prize: “Night & Day: St Kilda Hydro-Solar Generator” by Olson Kundig

Project description: “Olson Kundig partner Kevin Kudo-King says ‘Night & Day’ is a departure from the firm’s normal work in that visitors become part of the experience of generating renewables. Night & Day is designed to improve the connection between The Esplanade and Port Phillip Bay, in addition to providing a sophisticated educational amenity that is bound to draw scores of visitors.

During daylight hours, energy produced by a 5,400 m2 photovoltaic (PV) solar sail is used to directly power homes while also safely pumping bay water into a suspended hydro battery vessel. After sunset, water is released through two Pelton turbines, transforming the kinetic movement of water into electricity through a generator—a proven technology that is already used at the utility scale, according to Kudo-King.”

Third place/special mention: “Swings” by Lu Chao, Weng Shenxia

Project description: “When the sea breeze blows through the bustling Port Phillip Bay, it drives a group of huge swings into gentle sway. People come to watch and participate from the neighborhood, the beach, the Palais Theatre, and Luna Park.

During the day, the blades made of solar panels convert the sun’s energy into electricity, while wind and human energy collaborate to provide even more. When the sun has set and the visitors have gone home, the swings continue to sway gently in the sea breeze, glowing softly and providing a steady stream of electricity throughout the night.

Working in harmony with nature, Swings presents no threat to birds and takes up little ground space, allowing plenty of room  for people to engage in various activities throughout the site.

The top wing blade takes different positions as it generates power through movement. At first it sits perpendicular to the wind direction. As it catches the wind, the blade rotates and the soft rubber seat below sways to the side. With the seat at 15 degrees from center, the blade is rotated parallel to the wind direction, allowing it to slice through the wind and return the swing.

This movement can be generated by the wind alone or driven more quickly with human interaction. When the seat swings to the lowest point, the blade turns, receiving even more wind power. The blade’s rotation is managed by means of a repurposed mechanical recirculating ball system—like those used in the power steering assemblies of trucks and off-road vehicles—which is connected to a generator that converts mechanical energy into electricity.

As visitors contribute to producing a flow of electricity, Swings turns human activity and joy into a sustainable energy source.”
