Our commitment to environmental sustainability.
Fed Square faces a unique set of environmental challenges because it is a multifaceted precinct with major public events, complex infrastructure, cultural institutions and a range of commercial operations.
Through close collaboration with tenancies, partners and public stakeholders, Fed Square has achieved great results in the area of environmental sustainability and is now a carbon neutral city precinct following an independent external Green House Emission Audit by Earth Systems Pty Ltd.
The environmental milestone is a well-earned achievement after years dedicated to a sustainability management plan for key environmental areas including water, waste and energy.
Since 2008, Fed Square has reduced its electricity consumption by more than 4.1 million kilowatts, reduced gas consumption by over 12,000 gigajoules, increased the amount of recycling by 73% and saved 89 million litres of water – that’s approximately 35 Olympic swimming pools of water.
At the 2016 FM Industry Awards for Excellence, Fed Square won the Sustainability and Environmental Impact award for achieving carbon neutrality.
Laying the foundations
Long before phrases like carbon footprint became front of mind, Fed Square was laying the foundations for environmental sustainability. Beneath the Square for example, lies a concrete labyrinth; a 1.2km passive cooling system, designed to cool The Atrium, Deakin Edge and some public areas during summer and to supplement heating during winter.
Utilising the specific climatic qualities of Melbourne, cool air is pumped through the Labyrinth’s cells at night, cooling the concrete walls. By day, air is gently pumped through the cells, the air cooled in turn by the concrete walls. In winter the Labyrinth’s thermal mass maintains an inherent warming potential that can be supplemented as required. The system directs air to The Atrium, dispersed by use of a low-velocity displacement system at floor level. In peak summer conditions, the Labyrinth is capable of delivering air to The Atrium at up to 12°C below the external temperature. This system uses one tenth of the energy used by conventional air conditioning and drastically reduces carbon emissions.
Further design features include: double glazing on all external windows, a sleep mode for escalators, variable speed drives on A/C pumps and a hermetic seal in The Ian Potter Centre: NGV Australia, which reduces air conditioning requirements by over 50%.
Fed Square has a comprehensive environmental management plan that underpins daily operations. This plan focuses on the delivery of environmental sustainability measures across six categories: water, waste, energy, air, noise and landscaping.
As a result of this plan Fed Square Pty Ltd has implemented a range of initiatives including:
- Installation of 88 water tanks
- Upgrade works to the Cooling Towers to improve water efficiency
- Installation of a rainwater filtration system in the Fed Square Car Park
- Installation of waterless urinals and AAA showerheads
- Implementation of commingle and paper recycling across the site
- Introduction of organic recycling across the site with a bio-gas plant
- Installation of thermal energy meters to monitor air conditioning usage
- Installation of sensor lighting in key areas
- Purchase of Green Energy for all events in The Square, Fed Square offices and the Fed Square Car Park
- Tenant education program
Fed Square has also installed a co-generation plant, which one of the first of its kind to be installed in an urban setting such as a city square. The goal is to now become carbon negative. Watch this space for progress news over the coming years.
Fed Square takes a lead role in sustainable partnerships with the community and environmental groups. Each year, the site is host to the Sustainable Living Festival, Earth Hour, Fair@Square and many other promotional activities including clothing exchanges, sustainable architecture forums and environmental exhibitions.
Fed Square works with Melbourne City Rooftop Bees to manage 10 beehives on the roof of the Alfred Deakin Building (ACMI). Of all the food we eat, 65 per cent is dependent on honey bee pollination, yet honeybees in Australia are at high threat from Asian honey bees, Varroa Mite and colony collapse disorder. Urban beekeeping is one way in which to support the diversity in the species that will help it build a resilience to such threats. Fed Square’s rooftop apiary is the largest in Melbourne and produces in excess of 35 kilograms of honey, which is used in the restaurants and cafés on site to use in their specials.
