Urban developments built now and into the future will have
a lasting effect on the sustainability of our cities. A strategic
approach to the delivery of sustainability measures in
design, technology and place creation, is critical to ensure
that projects can systematically address their environmental
impact in a cost effective manner.
In partnership with Tract Consultants
and the City of Greater Geelong,
Moreland Energy Foundation
has developed this framework to
guide the process of embedding
sustainability into the Precinct
Structure Plan for the Armstrong
Creek Town Centre.
This framework links high-level
principles to the delivery of ‘on-theground’ opportunities and success
indicators, through all stages of
development; from the precinct
structure plan phase through
masterplanning, detail design, and
construction to operation.

Introduction
On behalf of the City of Greater Geelong
(CoGG), Tract Consultants is leading a project
team in preparing a Precinct Structure Plan
(PSP) for the Armstrong Creek Town Centre
(ACTC) as part of the Armstrong Creek Urban
Growth Area.
Moreland Energy Foundation (MEFL) has
been engaged to provide technical input
into the ACTC PSP on matters relating
to environmental sustainability. MEFL’s
methodology is guided by the ‘Sustainable
Urban Development Framework’.
This methodology as applied to ACTC has
involved:
•
Desktop research and gaps analysis to
provide current context of sustainability
in precinct structure planning practice
and precinct urban development
broadly including referencing of national
and international case studies.
•
Review of relevant resources, policy
and previous strategic work to resolve
site-specific sustainability principles
and targets for Armstrong Creek Urban
Growth Area and Major Activity Centre.
•
Internal stakeholder workshop,
collecting ideas and challenges for the
site to develop a clear set of priorities.
See Appendix A for the summary of this
workshop.
•
Identification and analysis of specific
opportunities across key sustainability
areas at the precinct structure plan level
(this created the ‘opportunity set’ for
sustainability across the site including
identifying challenges to delivery).
•
Analysis of relevant precinct and
building sustainability assessment tools.
Geographic context
The Armstrong Creek Town Centre (ACTC) is
located south of Geelong, bordered by Boundary
Rd to the north, Barwarre Rd to the east, Burvilles
Rd to the south and Surf Coast Boulevard to
the west. The ACTC is located central to the
broader Armstrong Creek Urban Growth Area
(ACUGA) of 2,687 hectares. The proposed use
of the remainder of the ACUGA is predominantly
residential with two major employment precincts
in the north-east (near Marshall) and to the west,
north of Whites Rd.
The PSP for ACTC is one of a number of PSP’s
being prepared for the ACUGA. The land is
currently used for farming purposes with the
southern and western parcels of the ACTC owned
by developer interests, with original land owners in
the northern and eastern parcels.
The area is largely devoid of remnant vegetation,
however some significant vegetation has been
retained along roadsides and in isolated clusters.
Drainage of the land is to the east in the eastern
section of the land and to the south-west in the
western portion.
The outcomes are documented in this ACTC
Sustainable Urban Development Framework
background report.

February 2011
This report integrates civil infrastructure under one delivery plan. It highlights the need for
supply and demand energy solutions, outlines objectives for integrated water management and
establishes priority for sustainable transport modes.
Phase 1 consultancy reports - ACTC
These reports provide key inputs into the preparation of the PSP for ACTC, outlining key
infrastructure requirements and initiatives that will assist delivery.
Strategic policy context (cont.)
The strategic work already undertaken for
ACTC demonstrates significant support for
the town centre to deliver a high standard
of environmental sustainability. A number of
general issues or opportunities have emerged
through the analysis and sustainability and
placemaking workshop, as outlined below:
Place manger
The ability to ensure momentum and
stakeholder engagement to deliver the plan
over time is a key issue for the overall project
and also for delivering on environmental
sustainability for ACTC. It is recommended
that a funding mechanism be incorporated
into the PSP for a place and sustainability
manager to drive implementation of the PSP.
This is a logical and highly practical method of
assisting in delivery of longer term initiatives,
including behaviour change initiatives that rely
on engagement with a yet to be established
residential and business community.
Sustainability ‘trajectory’
A PSP must deliver a long-term vision for the
community and a means for staged delivery of
development, often over considerable timeframes.
In this context, is it important to acknowledge
the rate of innovation that has been achieved
in the urban development sector with regard to
sustainability in recent times.
A prominant example has been the recent
improvement of residential energy efficiency
standards. These were introduced less than
a decade ago and have advanced since then,
however in that short time have become accepted
as ‘business as usual’.
This ongoing innovation will deliver further
rapid and significant change to accepted and
achievable environmental performance in
development. The PSP must recognise this
‘sustainability trajectory’, firstly by ensuring that as
future technologies became available and viable
provisions are made to enable retro-fit.
Secondly the PSP must recognise that today’s
Page 6
Sustainability at
Armstrong Creek
Town Centre
Sustainability ‘trajectory’ (cont.)
best practice is tomorrow’s industry standard
and either build in long term and interim
targets into the PSP or mandate a defined
improvement over and above a standard
that already regularly responds to changes in
achievable environmental performance.
Looking again at residential thermal efficiency
as an example, the National Construction
Code (NCC) standard (currently 6-star, having
improved from 5-star in May 2011) can be used
as a reference point for future requirements. By
mandating either a percentage, measurement
unit or star improvement over and above this
type of minimum standard the PSP can ensure
that targets ‘move with the times’.
Thirdly, by detailing the more prescriptive
standards within a Design Guidelines document
which sits as a reference document to the
planning scheme and undergoes periodic
review, sustainability standards may be
updated and kept responsive to the high level
of commitment to environmental sustainability
within ACTC without a planning amendment
being required.
Split incentives and business cases
A number of opportunities have been identified
where an investment in sustainability is made
by one party with the benefit at least partly
derived by others. A key next step for a number
of proposed initiatives will be to develop robust
business cases and for CoGG to explore and
facilitate innovative delivery models for these
opportunities.
evaluate and report against targets, which in turn
can reinforce business cases for ACTC and other
projects.
Dual benefit and visible sustainability
The opportunity exists for a number of proposed
sustainability initiatives to also deliver on placemaking and other objectives. For example
setting targets for street tree coverage makes
a contribution to reduction in urban heat island
effect (and therefore improved energy efficiency)
and improves the overall landscape and visual
amenity and biodiversity value of the centre.
Additionally a sense of ownership and
awareness can be fostered through ensuring that
environmentally sustainable initiatives are ‘visible’
and well communicated to the community where
practical, (e.g. through interpretive signage and a
dedicated sustainability ‘exhibition’ or education
space, as part of council facilities or an on-site
developer display centre.)
Adaptation
Many of the opportunities also contribute to
preparing the town centre for future changes
in climate. Adaptation strategies are cognisant
that the development decisions made now have
a far reaching effect on the ability for a future
community to be resilient against rising energy
costs and the environmental impacts of climate
change; a hotter climate and more variable
weather patterns. This ability for a precinct to
have some control over its own energy demand
and generation and water sources will become
increasingly valuable under climate change
scenarios.
The long-term nature of the PSP’s
implementation also allows scope to capture
savings and re-invest in sustainability within
the centre. This highlights the need to monitor,
Page 7

Town Centre
Implementation
The desirability of sustainability initiatives ‘on
the ground’ is a function of the difficulty of
implementation (i.e. barriers such as lack of
precedent, long delivery time frames, cost) and
the level of impact (reductions in greenhouse
gas emissions, potable water use and waste to
landfill).
Where sustainability initiatives have been found
through analysis and stakeholder engagement
to be low impact and high difficulty, these are
not recommended for ACTC.
High impact, high difficulty initiatives have
been treated selectively, with greater priority
assigned to those with demonstrated council
support, dual or visible benefits and ability to
demonstrate the highest impact at the lowest
cost.
This report classifies strategies for
implementation of environmental sustainability
through three main delivery mechanisms;
3.
Land owner leadership – the strategy
relies on leadership, cooperation or significant
buy-in from the site’s land owners and/or
developers. It is also likely that these initiatives will
require collaboration with other stakeholders such
as developers, state government departments or
utility authorities.
Sustainability leadership for land owners at ACTC
offers a range of benefits. In addition to reduced
operating costs through energy savings, improved
visitor comfort and health, prominent household
brands will have an opportunity to demonstrate
their genuine commitment to sustainability through
the delivery of innovative buildings and facilities.
Together, these present the opportunity for a
‘green brand’ for the town centre to be developed,
furthering the value to individual businesses.
The potential for precinct-scale solutions in
sustainable energy, waste and water, also
presents a significant opportunity to be a leader in
innovation while also sharing costs.
Planning tools – the strategy can be
1.
partially or fully delivered through statutory
mechanisms including planning policy changes,
zones and overlays, the PSP or Design
Guidelines.
2.
Council leadership – the strategy relies
on leadership from council, either through
the development of their own assets or as
a facilitator of further strategic work. These
opportunities for leadership also create a role
for communicating success (e.g. GHG or water
savings) to the community; monitoring and
evaluation is key to demonstrating value.
Council’s leadership of sustainability at ACTC,
on all levels, offers a chance to stand out
as a local government leader. Additionally,
the project outcomes will assist in meeting
Council targets for corporate and community
greenhouse gas emission reduction targets,
while obtaining valuable lessons and insights
readily applicable to other Council and
community projects.

Energy efficiency
Introduction
Energy efficiency is one of most cost effective ways of reducing
greenhouse gas emissions, and can also be one of the easiest
approaches to implement. It often involves relatively subtle changes
in design, materials and the systems that are incorporated into a
building, that in many cases have low cost impacts, particularly if
changes are made very early in the design process.
Energy efficiency concepts
Armstrong Creek Town Centre Context
Thermal performance refers to a building’s ability to maintain
a relatively stable internal temperature. Thermal performance is
affected by many factors including; building orientation, location
and size of windows and eaves, use of natural ventilation, and
construction materials, insulation and draught sealing.
The ACTC is well placed to deliver on opportunities to showcase
highly energy efficient building and precinct design.
Energy efficient appliances include both fixed and non-fixed
devices such as lighting, whitegoods, heating and cooling
systems. When considering the relative energy efficiency of one
system compared to another it is important to also consider the
carbon intensity of the fuel source (e.g. electricity versus natural
gas).
Urban heat island effect occurs in urban areas where buildings,
roads and non-natural forms absorb and retain heat. Heat islands
can increase summertime peak energy demand, air conditioning
costs, air pollution, greenhouse gas emissions and heat-related
illness. Measures to reduce urban heat island effect include
increasing vegetation, large scale green roofs and walls, and
using light coloured cladding and finishes.
A green roof or wall’s main purpose is to regulate internal
building temperature by reducing heat retention and acting
as insulation. They can also improve local air quality, enhance
biodiversity, reduce the impact of storm water runoff, provide a
relaxing space for residents and reduce the urban heat island
effect.
Building management systems control the active systems
within a multi-unit or commercial development to optimise
management for energy efficiency.
The target set for all buildings to go ‘beyond compliance’ in
comparison to the current regulatory NCC standard will contribute
to the precinct’s operational energy being up to 30% lower than
other town centres of similar scale.
The key challenge will be to deliver on these targets over time and
to limit the urban heat island effect through innovative approaches
to car parking provision and increased tree coverage.
Case Study
Supermarkets are big energy users, but also have available
to them a range of options to significantly reduce this energy
intensity.
In its ‘environmental concept’ store at Melbourne Showgrounds
in Flemington, Coles demonstrated a range of innovative energy
efficiency measures. These include highly efficient air-conditioning,
LED lighting and recycled materials (to lower embodied energy).
Woolworths has also capitalised on opportunities to improve
operational efficiency in its Victoria Harbour store. Automatic
night blinds on upright refrigeration areas, cascade refrigeration
systems, use of natural light, high efficiency lighting technologies
such as T5 fluorescents and heat-recovery all contribute to
significant reduction in operating energy requirements.

On-site energy generation
Introduction
The vast majority of Victoria’s electricity generation facilities are
located a significant distance from the end point of use. This
centralised electricity system sees up to 70% of the fuel’s potential
energy lost during generation, transmission to urban areas and
distribution within towns and cities.
On-site energy generation can reduce transmission losses by
being located close to the final point of electricity use. Additionally,
on-site generation that uses low-carbon or renewable resources
can significantly reduce the greenhouse gas emissions associated
with fossil fuel based generation.
Analysis undertaken by Sustainability Victoria in 2009
demonstrated a strong business case for the consideration of
on-site energy generation at Armstrong Creek. Further, more
detailed analysis is required to further this exciting possibility, and
collaboration between a range of stakeholders will be critical.
On-site energy generation concepts
Armstrong Creek Town Centre Context
Solar water heating systems use solar radiation to heat water.
When there is insufficient solar radiation, systems have either gas
or electric boosters to heat water.
The large scale of ACTC offers significant scope for on-site
energy generation, with significant opportunity for roof top solar
PV and co-gen / tri-gen technologies.
Photovoltaic (PV) panels convert solar radiation into electricity
without producing any emissions. PV panels are long lasting and
require very little ongoing maintenance.
Given the significant up front costs associated with on-site
generation CoGG leadership will be required to provide the initial
momentum for the development of a sound business case and
to investigate innovative funding models that can outsource risk
to third parties and demonstrate a commercial return to building
owners.
Wind power is the use of wind to turn a turbine that generates
electricity. Micro wind turbines are small rooftop mounted wind
turbines suitable for use in urban areas.
Waste to energy is the process of creating electricity or heat
from waste. Biological or thermal processes are used to break
down the waste, leading to significant potential emission
reductions.
Cogeneration, or combined heat and power (CHP), is the
recovery and use of heat created as a by-product of electricity
generation to provide another energy service. This waste heat can
be used to heat water or air or to create steam.
Tri-generation converts the waste heat from cogeneration into
cooling using absorption chilling.
Micro-grids are private energy networks that support single or
multiple buildings on one or multiple sites and can be supplied by
one or more on-site energy generation systems.
Embedded networks enable the private distribution and sale of
energy within a building.
Case Study
Dockside Green, a leading sustainable precinct development
in Victoria, Canada, demonstrates how a range of the onsite generation opportunities present in many mixed-use
developments can be implemented.
The project has delivered a range of innovative on-site energy
generation measures, the most significant of which is a biomass
fuelled district heating system, which provides all the heating and
hot water requirements of the 6 hectare site. This system also
captures the waste heat from the site’s blackwater treatment
plant and has begun to export surplus heat to surrounding sites.
The plant is operated by a purpose created energy services
company Dockside Green Energy, which is responsible for
maintenance, customer connections and billing.

Strategy for Armstrong Creek Town Centre
Solar water
heating
If every building was fitted
with solar collectors to provide
domestic hot water, electricity/
gas use in operation would be
significantly lowered.
Infrastructure - Gas
reticulation infrastructure likely
to still be required for boost.
Industry accepted measure Relatively standard delivery for
residential development
Planning tools
• Design guidelines to require all buildings
to source a proportion of hot water energy
requirements via solar.
• Design guidelines to consider impact of
overshadowing on solar access to energy
systems for neighbouring buildings.
Council leadership
• Utilise solar hot water systems in all Council
facilities.
Photovoltaic
(PV) panels
PV can dramatically lower
use of grid electricity as well
as reducing peak load. This
could reduce distribution and
transmission infrastructure
augmentation requirements,
providing significant capital
cost savings.
Upfront cost - The initial
cost of the infrastructure can
be prohibitive to large-scale
deployment, however prices
are dopping consistently and
rapidly.
Innovation - New models of
delivery of PV are emerging,
including leasing arrangement
for roof space with a guaranteed
return to the building owner.
Visible - Easily recognised and
well understood technology
Planning tools
• Require all buildings to source a proportion
of electricity requirements via PV.
• Design guidelines to consider impact of
overshadowing on solar access to energy
systems for neighbouring buildings.
• Design guidelines to require consideration
of future PV installation in roof design,
particularly on large commercial buildings.
Council leadership
• Council facilities to incorporate PV systems
wherever practical.
Land owner leadership
• Encourage large roof area buildings to make
unutilised roof space available for rent for
aggregated solar array (at reasonable rate).
• Commercial tenants may be attracted
to a leasing approach, reducing upfront
capital and realising savings during ongoing
operation.
Micro wind
turbines
Micro wind turbines are an
emerging technology and can
provide an additional source
of on-site renewable energy
to reduce emissions and peak
load.
Upfront cost - The initial
cost of the infrastructure can
be prohibitive to large-scale
deployment.
Emerging technology - yet
to be widely employed outside
of demonstration projects in
Australia
Land owner leadership
• Micro wind turbines may be appropriate for
roofs of retail and office buildings; work with
key developers to identify opportunity for
demonstration installation.
Waste to
energy
Waste to energy technologies
can significantly reduce waste
to landfill while generating
useful energy resources.
A consistent and suitable waste
stream is required.
Council leadership

Cogeneration
and
tri-generation
Cogeneration and trigeneration, when combined
with a district heating/cooling
network, have the potential
to revolutionise a precincts
energy use. Energy for heating,
cooling and domestic hot
water can be produced onsite from a low carbon source.
This significantly reduces
pressure on centralised energy
generation, transmission and
distribution infrastructure.
These technologies also bring
the potential for deployment
of ‘smart grid’ technologies,
making the grid more
interactive and responsive to
the demands of the buildings
connected.
Business case - Cogen/trigen
has a strong business case in
commercial buildings, leisure
centres, hospitals – largely
due to a high and stable heat
requirement. Deployment in
residential uses is less feasible,
particularly where high thermal
performance efficiency has
been delivered.
Feasibility - Cost / benefit
is impacted by certainty of
demand from larger customers.
Planning tools
• PSP to specify low-carbon on-site energy
generation as a priority opportunity.
• PSP to provide support for underground
thermal network servicing council facilities
and central commercial precinct to ensure
ability to cost-effectively connect in the
future.
• Design guidelines to ensure ability to connect
to a future district heating and/or cooling
network. Include in consideration of plant
room design and location.
• Provide for staged development by ensuring
generation capacity and distribution network
can be expanded as required.
Council leadership
• Facilitate the development a pre-feasibility
study for a range of on-site energy
generation scenarios, including central
services hub, multi building or single building
approaches. If strong business case, engage
with potential 3rd party operators (Energy
Services Companies), and commit council
facilities to connecting to a future network.
Land owner leadership
• Work with key commercial operators to
lock in power purchase arrangements, to
provide greatest degree of certainty on future
demand.
• Aquatic centre precinct, early retail/
office/supermarket development may be
appropriate as catalyst customers.
Micro-grids
Separate to the broader
distribution network, local
micro-grid can be a key
enabler of distributed energy
generation.
Feasibility - Likely to require a
3rd party operator to assume
risk.
Regulatory - Approvals can
be challenging due to current
energy market structure.
Planning tools
• Require consideration of opportunities for
micro-grid when high-level infrastructure
planning is being undertaken.
Council leadership
• Explore regulatory mechanisms to require
connection of buildings to local micro-grid.
Feasibility - Significant capital
costs and potentially poorly
performing compared to similar
technologies.
Thermal loads - need to
identify established thermal
loads
Planning tools
• Maintain flexibility in planning provisions for
deploying technology at the building level or
micro network scale. Assessment framework

Closing the gap
Introduction
It is often not practical or cost-efficient for developments to
attempt to achieve ‘zero carbon’ or ‘carbon neutrality’ via on-site
actions only. A range of issues mean that some energy needs
and residual emissions are better addressed through other
mechanisms.
Critical in this is ensuring that the environmental credentials
of any off-site mechanisms are carefully verified to ensure the
development can be confident in any claims made. This section
describes actions that can be taken in order to address any
residual emissions.
Key concepts for residual emissions
Armstrong Creek Town Centre Context
Off-site energy generation is the production of energy using
renewable or low-carbon resources at a site other than the main
development.
The scale of ACTC will allow a suite of technologies to be
delivered on-site, reducing the need for dedicated off-site
generation. Voluntary schemes such as GreenPower and carbon
offset arrangements will be encouraged through the proposed
Place and Sustainability Manager role.
GreenPower is a government-accredited scheme for electricity
generated from renewable sources. Purchasing GreenPower
ensures the equivalent percentage of annual electricity
consumption is sourced from zero net emission sources.
Carbon offset programs invest in measures that compensate
for emissions such as; renewable energy generation, energy
efficiency, methane reduction and forestry. Developments
promoting themselves as ‘zero carbon’ or ‘carbon neutral’ need
to consider independently certified or accredited offsets.
Case study
The Western Harbour urban renewal district in Malmo, Sweden,
was developed under a set of ambitious targets for sustainability
across energy, water, waste and transport. The project,
developed on remediated industrial land, incorporated a range of
features to reduce its carbon footprint and energy consumption
as much as possible, as well as incorporating some on-site
energy generation through solar panels and solar hot water.
A commitment to 100% renewable electricity meant that
the remaining electricity needs for the site had to be met by
another sustainable source, and the project partners ultimately
commissioned a 2MW wind turbine on a separate site nearby.
This renewable energy generator was financed and built as a
direct result of the project.

Off-site energy
generation
On-site generation potential is
unlikely to meet full demand for
energy. A directly attributable
off-site renewable energy
project may allow the project to
reach net carbon neutrality.
Upfront cost - Initial cost may
be significant.
Additionality - Question
of ‘additionality’ can be
challenging.
Council leadership
• Explore nearby renewable energy resources
for potential sites
• Explore opportunities to link with existing
community groups with an interest in local
renewable energy projects.
• Power purchase agreement with key
tenants and/or local ESCo may be critical to
feasibility.
GreenPower
Encourages investment in new
renewable energy sources
which helps to lower the overall
emissions intensity of grid
electricity.
Purchasing 100% accredited
GreenPower would save an
average Australian home
approximately 7 tonnes of
emissions per year, equivalent
to removing almost two cars
from the road.
Cost - GreenPower does
pose an additional cost to
customers.
Uptake - Owners/tenants
are free to choose their
own electricity retailers and
products hence purchase of
GreenPower may need to be
incentivised.
Voluntary action which could be encouraged
through behaviour change strategies. The Place
Manager may play a role in providing future
residents and businesses with information on
GreenPower.
Carbon
offsetting
Can compensate for all
emissions associated with a
specific activity or all aspects
of the development and the
lifestyle of its residents. Carbon
offsets can also support
important initiatives including
tree planting, renewable energy
generation and large-scale
energy efficiency programs.
Administration - Periodic
emissions calculations would be
required to allocate the cost of
carbon offsets across residents
on an equitable basis.
Concerns exist with the integrity
of some offsets marketed, and
confirming the integrity of these
can be difficult.
Voluntary action which could be encouraged
through behaviour change strategies - could
include links to any local carbon farming
initiatives.

Demolition and construction
Sustainable Zero
waste
urban
development
Introduction
Over 75% of waste generated during demolition and construction
is clean excavated material, concrete, bricks and timber which
are all highly recyclable. Reduction of construction waste is an
opportunity to significantly increase resource efficiency and
reduce project costs.
Demolition and construction concepts
Case study
Design for sustainability in this context includes actions such as
designing for longevity and deconstruction, designing to standard
material sizes to avoid excess and incorporating recycled and
recyclable materials.
VicUrban’s mixed-use development ‘The Nicholson’, located
in Melbourne’s inner-north, has utilised an innovative modular
construction system in tandem with traditional construction
techniques. This innovative modular construction method has
a number of advantages over more traditional construction
methods including the speed of delivery, higher quality control
over apartment fit out and occupational health and safety benefits
during the construction process with, for example, workers
exposed less often to working at heights.
Optimum value engineering and advanced framing techniques
may result in lower material and labour costs and improved
energy performance for the building. The technique can
be applied as a package or its components can be used
independently, depending on the specific needs of the project.
Waste management plans for demolition and construction
contractors include targets for resource recovery, identification
of the destination of material types, and reused and recycled
materials quotas.
Prefabricated modular construction occurs in a factory, rather
than on-site. More efficient use of materials and standard sizing
can be achieved by constructing a housing unit using a factory
manufacturing process.
It has also helped the project to improve the thermal performance
of the building, reduce material wastage and reduce the reliance
on materials with high embodied energy. By constructing the units
in a factory environment, material dimensions can be more easily
standardised and greater precision ensures fewer components
are damaged or wasted during assembly.

Waste avoidance and recycling
Sustainable Zero
waste
urban
development
Introduction
The household sector in Australia generates almost 12 million
tonnes of solid waste every year, and only 38% of this waste is
recycled. Over one third of household waste is organic including,
food and garden waste. When organic material breaks down in
landfill methane emissions are released which account for 3% to
4% of Australia’s greenhouse gas emissions. Diverting food waste
away from landfill reduces greenhouse emissions and can create
valuable resources, such as compost.
Waste avoidance
Armstrong Creek Town Centre Context
Waste management infrastructure refers to facilities that
enable good waste separation and management. Examples
include underground precinct vacuum waste collection systems,
providing separate garbage and recycling chutes in high density
buildings and providing communal storage areas for recyclable
materials that are not collected through kerbside services (e.g.
batteries, e-waste and light globes).
The ACTC has potential to deliver innovative solutions for
waste avoidance, with scope for a number of technologies and
behaviour change strategies to be employed. A precinct-wide
underground waste collection system has potential, however will
be reliant on early provisioning in infrastructure plans and a strong
business case.
Differential pricing involves charging households and businesses
per unit of waste they dispose of to landfill, incentivising waste
avoidance, recycling and composting.
Small scale resource recovery includes composting hubs or
worm farms for the on-site treatment of organic materials such as
kitchen scraps.
Large scale resource recovery includes either on or off-site
facilities to process either the organic component of household
garbage or the entire waste stream.
Non-standard recycling services can be introduced for
products or materials that are not recyclable through the kerbside
collection service, such as batteries and household appliances.
The need for these services should be determined with reference
to the recycling services provided by local councils via hard waste
collections and at resource recovery centres.
Product sharing involves households and businesses
sharing infrequently used items, such as tools or appliances.
Environmental benefits arise from reducing the amount of goods
that each household needs to purchase, and ultimately dispose
of. This can be undertaken through formal schemes such as The
Sharehood, or informally between neighbours.
Goods libraries are membership-based loan services for
infrequently used items such as tools.
As the responsible authority for waste collection CoGG has an
opportunity to demonstrate leadership through the development
of a comprehensive waste management plan for the precinct
which challenges the BAU approach. It can also lead by initiating
discussions between key stakeholders including the developers,
infrastructure providers and waste management authorities.
Case Study
Hammarby, a major urban regeneration project delivered close
to Stockholm’s city centre in Sweden, took a highly innovative
approach to waste management at the site. To satisfy a series
of goals around waste management, including improved waste
stream separation, reduced greenhouse emissions through
efficient waste collection and improved amenity through reducing
vehicle movements and odours, the project installed a highly
efficient ‘Envac’ automated waste management system.
Using a network of underground pipes connected to fixed waste
disposal points in public places and adjacent to apartment
buildings, the system uses vacuum to suck waste to collection
points for transfer to recycling facilities and landfill. The system
has been shown to significantly improve the separation of
recyclable materials and has ensured the precinct is not subject
to a weekly ‘invasion’ by a fleet of garbage trucks.

Reducing the need to travel
Introduction
Many daily travel needs are created by the separation of residential
areas from land uses that support jobs, shops, key services,
schools and recreation. By creating areas that support multiple
uses, or locating new residential development close to existing
services and infrastructure, the need to travel can be reduced
significantly.
Key concepts
Armstrong Creek Town Centre Context
Mixed use developments are those that combine residential,
commercial, recreational and/or community amenities in close
proximity.
The ACTC is well placed to reduce the need to travel, based
on a strong mix of uses and an ability for individual trips to the
centre to service a wide variety of needs. The size of the town
centre at approximately 1.2km by 800m, provides opportunity for
delivery of a truly sustainable mixed use precinct, subject to the
detail design stage ensuring that complementary uses having well
defined pedestrian connections between them.
Small office or home office residences offer both residential
and office amenities such that people may work where they live,
including the ability to meet with clients.
Recreational facilities include parks, barbeques, gyms, pools
and tennis courts.
Key services include offices, shops and cinemas, postal,
banking, medical and childcare services.
Communal facilities can comprise of a combination of
recreational and commercial amenities that are available for use
by residents and businesses in the development. Depending on
the scale of the development these could include meeting rooms,
function areas, lecture theatres etc.
Business service providers are private organisations that rent
out meeting spaces and offices, as well as providing reception
and telecommunications facilities to businesses.
Case Study
Melbourne’s hierarchy of Activity Centres is based on identifying
key precincts that contain a mix of particular uses and community
facilities. ‘Principal Activity Centres’ and ‘Central Activities
Districts’, such as Dandenong, Footscray and Coburg, are
places which can support significant employment, residential
development, key community services and are serviced by good
transport services. They also represent the ability to establish
areas where the need for travel between work, home and
recreation is reduced.
Moreland City Council’s The Coburg Initiative - a major urban
renewal project at Coburg Principal Activity Centre - aims to
create an environment suited to ‘5 minute living’, where key daily
needs are within an easy 5 minute walk. By combining higher
density residential development with key community services,
diverse retail and commercial uses, a pedestrian-focused
environment and communications infrastructure such as high
speed broadband, the precinct will present opportunities for many
residents to work, live and play without significant travel.

Introduction
Cars now dominate most Australian cities. While they can provide
valuable mobility for some needs, they can also reduce the quality
of life in our cities, and the ability to get around using other means.
For many daily transport needs, cars are not the best option.
Reducing private vehicle use has many benefits including financial
savings for individuals, reduced congestion, reduced noise
pollution, reduction in required parking spaces, increased safety
and reduced greenhouse emissions.
Key concepts
Armstrong Creek Town Centre Context
New public transport infrastructure may be delivered as part of
large development projects. This could include adding new stops
or interchanges to an existing route or establishing a new train,
tram or bus route.
Reducing private vehicle use within the ACTC will rely on early
delivery of a variety of key infrastructure items within the town
centre. The key items include high frequency bus services to
the regional catchment, a dedicated public transport (PT) link to
Geelong and successful travel behaviour strategies.
Encouraging public transport use through the provision of
information, incentives and linking infrastructure can make public
transport an attractive alternative for the majority of trips.
Car share schemes provide members with access to a vehicle
without some of the major costs of owning one. This means
people can access a well maintained car on the irregular
occasions they need one, without having to pay registration,
insurance and servicing costs.
Centralised car garaging involves storing cars separately to
dwellings, and ensuring other transport modes such as cycling,
walking and public transport are convenient. Residents that
require a car park can purchase a space in the car garage.
Carpooling is the sharing of journeys so that more than one
person travels in a vehicle.
Oversupply of car parking in the centre is a risk to a sustainable
town centre, promoting the convenience of private vehicle travel
above more sustainable travel modes.
Case Study
The Adelaide O-Bahn operates a 12km long dedicated service
with minimal stops from the eastern suburbs to the Adelaide city
centre.
The service carries more than 7 million passengers a year with
the ability to move 18,000 people an hour in each direction.
The cost of the infrastructure (including the bus fleet) was just
under $100 million, considerably cheaper than heavy rail.

Plug-in hybrid electric vehicles (PHEV) allow the batteries to be
charged using the electricity network. PHEV connected to ‘smart
grids’ can be charged using off-peak electricity supplied from
base load generators and renewable energy generators.
100% electric vehicles have zero tailpipe emissions. Electric
vehicles powered using low or zero emissions electricity offer the
potential to reduce greenhouse emissions from private transport.

Centralised car
garaging
The urban infill mixed use
development in the suburb of
Vauban in Freiburg, Germany,
utilised this approach,
contributing to a significant
reduction in car ownership
and usage. It also created a
better urban environment that
prioritised people over vehicles.
Economic: Opportunity to
decouple apartments from
car parking provision allowing
residents to purchase a car
park as an additional extra.
Early adopter: Market demand
for car-free development
is yet to be proven outside
Melbourne.
Design: Distance to centralised
car garaging needs to be
minimised to be viable option
– good opportunity exists with
staged residential development
of multiple buildings.
Dual benefit: Can increase
affordability of residential
apartments for those who do
not require a car space.
Planning tools
• PSP and Design Guidelines to incentivise
centralised car garaging for staged
development including support for
decoupling car titles from residential and
office uses where practical.
Council leadership
• Work with commercial and residential
developers to undertake pre-feasibility study
to determine suitability of alternative models
of car parking ownership / delivery in ACTC.
Land owner leadership

portions of land suitable for both car parking
provision or higher uses, with a review
period to determine whether car parking is
‘actually required’ or whether the land can be
developed for higher uses.
Carpooling /

Active transportation
Introduction
Greater adoption of active forms of transportation, including
bicycling and walking, is beneficial to both the environment and for
the health of individuals. Active forms of transport can also reduce
traffic congestion and demand on limited parking.
Giving pedestrians and cyclists the highest priority in the design
process will encourage active forms of transportation within and
around a site as it moves into operation.
Strategies to foster active transport
Armstrong Creek Town Centre Context
Sustainable travel planning creates a blueprint for a
development to achieve a sustainable, convenient and safe
transport system and behaviours.
The ACTC proposes a network of well defined on-road and offroad pedestrian and cycling infrastructure. The key to successful
delivery of a town centre that fosters active transport will be the
issues of priority, safety, legibility and amenity, objectives which
mirror place making objectives for the town centre.
End-of-trip facilities provide bicycle riders or walkers with secure
storage, shower and changing facilities at their destination.
Safe and conducive environments encourage walking and
cycling.
Mode interconnection refers to being easily able to change
between rail, bus, tram and bike. It requires a focus on proximity,
safe and clear connection between modes, facilities and timetable
coordination.
Case Study
The Commons, a Brunswick development comprising
apartments, artist studios and two retail tenancies, has taken
the bold step of becoming one of the first truly ‘car-free’
developments in Melbourne. The site’s location close to high
quality public transport infrastructure, the mixed-use hub of
Sydney Road and other key services means that residents
potentially have low travel needs and a choice of public transport
options.
In addition to this, the project will foster a healthy lifestyle
supported by active transport choices. The site is located
immediately next to the Upfield bicycle path, providing
connections to the CBD and northern suburbs. Brunswick has
an established bicycle culture which continues to grow, and it is
expected that many residents will use bicycle for a variety of daily
transport needs.

Removes barriers to bike
ownership and regular
use, including fear of theft,
convenience and space.
Physical constraints Adequate space can be difficult
in higher density development.
Planning tools
• Design Guidelines to mandate best practice

attributed to international
examples:
Paris: 32,330 tCO2 / year
Copenhagen: 90,000 tCO2 /
year
Freiburg, Germany: 10,600

Cost - A purely commercial
operation may struggle to
achieve financial viability
(however the indirect social,
economic and environmental
benefits are significant.
Target market - Bike hire
schemes are more successful
where tourism levels are high.
Regulation – The need to
provide helmets for cyclist has
limited uptake in Australia – eg
CoM scheme.
Voluntary action which could be encouraged by
CoGG should demand be established.
Provision of
bicycle and
walking paths
85% of surveyed Sydney inner
suburb residents said they
would take up cycling if a safe
bike network was provided.
Dedicated bike paths in Cairns,
Queensland have increased
commuter bike use by 300%.
Research found that bicycle
parking in shopping areas in
inner Melbourne generated
over 3 times the economic
expenditure than car parking
generated.
Council - Ownership and
ongoing maintenance of paths
often become responsibility
of local government, requiring
early engagement and
commitment.
Social impact - Eases traffic
congestion, improves local air
quality, reduces noise pollution
and improves general health.
Access for all – Different
bicycle skill levels need
different infrastructure – with a
need to avoid conflict between
pedestrian and bicycle.
Planning tools
• PSP to provide for off-road bicycle paths
to major destinations within the ACTC to
complement on-road provision.

Construction and materials
Introduction
The use of sustainable construction materials can dramatically
reduce the ‘embodied’ environmental impact of a development;
that is, the resources that are needed to manufacture and
transport materials to their point of use.
Not all materials have the same impact on the environment, and
steel, bricks and concrete can have higher embodied energy due
to the greater levels of processing required in their production.
However alternative products, including recycled aggregate
concrete, can make a significant dent in this impact.
Construction and material strategies
Armstrong Creek Town Centre Context
Design for sustainability in this context includes reducing
consumption of resources by reducing house size, designing for
durability and reusability, reducing reliance on scarce materials
and incorporating materials with recycled content and low
embodied energy. This approach is also discussed in the Zero
Waste section of this document.
As a greenfield site, buildings within the ACTC will not have the
opportunity to reuse existing materials on-site. Instead the focus
of construction and material strategies will be at the building level
- to minimise embodied energy, increase recycled content and
ensure that materials are sustainably sourced and minimise waste
through efficient use.
Materials specification includes defining principles for the
selection of construction products. Sustainability principles
include preferences for reused, recycled, low embodied-energy,
and low toxicity materials as well as the use of materials from
sustainable sources.
Case Study
One Brighton, a development in the city of Brighton, south
of London, was delivered using the 10 principles of One
Planet Living created by BioRegional and included a focus on
sustainable materials specification. The project realised in some
cases it would be necessary to work extensively with suppliers
and sub-contractors to seamlessly incorporate new materials and
techniques into the building, and to do so cost-effectively.
Through rigorous research and careful negotiation, the project
was able to be delivered within a conventional construction
budget while incorporating a range of highly innovative materials
and construction techniques. Amongst other things, the site
achieved 49% (by weight) recycled materials, used 100% certified
sustainable timber products, minimised use of PVC and stipulated
use of low-VOC materials.

Sustainable consumption
Introduction
Building a sustainable development is just the beginning. Once the
development is occupied, there are many everyday decisions that
will affect the ongoing environmental outcomes achieved.
36% of Victoria’s ecological footprint is related to goods and
services, and a further 28% is due to food consumption. Through
minor changes to daily purchasing and consumption habits,
consumers can significantly cut their ecological footprint, and in
doing so support local traders and producers.
Key sustainable consumption concepts
Armstrong Creek Town Centre Context
Access to sustainable goods and services by exercising
control over the type of retail and/or commercial services available
within or used by the development (by the developer itself or
through the owners corporation) assists tenants and residents in
making sustainable decisions and purchases.
The ACTC, as a centre that will support a large residential and
business population, has good opportunity to develop sustainable
consumption behaviours based on economies of scale.
Green contracts require providers of services such as
cleaning, gardening and maintenance to deliver their services in
accordance with the environmental and social objectives of the
development. For example, the cleaning contract may require the
use of low toxicity or garden safe cleaning products.
Green leases require retail or commercial tenants to deliver their
products or services in accordance with the environmental and
social objectives of the development. These requirements typically
address the internal operations of the tenant, such as energy and
water use, and the products or services provided by the tenant,
such as a requirement for cafes to supply fair trade coffee or use
recyclable take away containers.
Buying groups can be established to facilitate the purchase of
environmentally and socially responsible products and services
such as low impact groceries, bicycle equipment and garden
safe cleaning products. By establishing these groups (typically
via an owners corporation), it can be easier for the occupiers
to purchase products and services that are consistent with the
environmental and social objectives of the development.
A medium term focus for a Place and Sustainability Manager will
be to facilitate awareness about the voluntary actions residents
and businesses can take to practice sustainable consumption.
Case Study
The 60L building in Melbourne was created as a showcase for
the future of sustainable office development, and ensuring that
the design and technology features were also coupled with
sustainable operations was a key focus.
The use of ‘green leases’ has been a key way of ensuring this,
with all tenants in the building required to enter into a green
lease that requires their ongoing commitment and support of the
building’s sustainability features. The lease also requires tenants
to make sustainable decisions when undertaking fit-outs or
renovations within their tenancy.
These conditions foster a culture of shared responsibility for
the building’s sustainability, which sees tenants collaborating to
achieve the best outcome for the building as a whole.

Sustainable food
Introduction
28% of Victoria’s ecological footprint is due to food consumption,
more than residential energy use and transport combined.
While awareness of the need to conserve water and reduce
energy use is prevalent, the environmental impact associated
with the production, processing, packaging, storage, transport
and disposal of food are less well known. However through
minor changes to daily food purchasing habits, consumers can
significantly reduce this impact.
Key concepts for water consumption
Armstrong Creek Town Centre Context
On-site food production can be encouraged through the
provision of garden allotments or planter boxes on balconies.
The staging of the town centre, with dedicated PT infrastructure
and residential development likely to be delivered in the medium
term, offers significant scope for on-site food production in the
short to medium term, with encouragement of a continual food
production role in conjunction with residential development.
Low impact food produces fewer environmental impacts
relative to other foods. The production process, packaging and
transportation will generally vary from product to product, but
generally, fresh foods and seasonal foods have a lower impact
than processed and packaged foods, while animal products have
a higher impact than non-animal based products.
Access to local fresh food amenities requires ensuring that
within the development or nearby there are sources of fresh food
that can be accessed by residents or tenants without the need for
private transportation.
Sustainable food waste management involves recovering
the valuable resources that are embodied in food waste, rather
than disposing of food waste to landfill. Options for sustainable
management of the organic waste stream are discussed in the
Zero Waste section.
A risk for the ACTC, will be to ensure that access to local fresh
food is not compromised by the land holder development mix of
primarily supermarket developers.
Case Study
In Australian cities a range of local produce delivery services are
emerging, such as CERES Fair Food, and small initiatives by
developers, such as delivery spaces or promotion, can support
residents making more sustainable food choices.

Introduction
The overall reduction of water use, and in particular potable water,
is the primary opportunity in developing a sustainable approach to
water.
Many measures, such as water efficient appliances and fittings,
are becoming common in new developments. These, combined
with minor behaviour changes, can make a significant difference
to our use of this limited resource.
Key concepts for water consumption
Armstrong Creek Town Centre Context
Water efficient appliances and fittings use less water
compared to similar products. Most appliances and fittings that
use water are now labelled according to the Water Efficiency
Labelling and Standards (WELS) scheme.
ACTC has the potential to promote highly efficient use of water
at the precinct scale. Whilst most appliances and fittings are
considered at the building level during detail design, at the
precinct level opportunities are available such as water efficient
landscaping and behaviour change strategies linked to specific
water targets.
Water efficient landscaping and gardens can reduce watering
and irrigation needs of individual households and the common
areas. This can include selection of indigenous and drought
tolerant plants, mulched garden beds rather than lawns and use
of subsurface irrigation and soil conditioners to reduce watering
needs.
Case Study
Regulation and changes in industry practice have meant that
new development in Victoria generally includes water-efficiency
fixtures such as taps and shower-heads. Other appliances,
such as washing machines and dish washers, can account for
a significant proportion of household water consumption and
represent another opportunity to reduce overall potable water
use.
Developer VicUrban (now Places Victoria) worked with Harvey
Norman to offer buyers at The Nicholson a discount on
appliances for their new apartment, with a focus on highly efficient
models. By providing an incentive for residents to choose high
efficiency appliances, VicUrban has been able to further influence
the ongoing sustainability of the project in a manner not normally
within the control of a developer.

part of its strategy to reduce
potable water consumption by
up to 40%.
Water efficient

Water reuse
Introduction
On-site water collection and reuse can significantly reduce potable
water consumption. Additionally, water reuse reduces demands
on centralised water treatment facilities, reticulated potable supply
and storm and sewage drains. It also reduces or avoids the need
for infrastructure upgrades, resulting in significant cost savings
over time.
Key concepts for water reuse
Armstrong Creek Town Centre Context
Rainwater usage requires the installation of tanks to collect water
runoff from roofs. Rainwater can be connected to toilets, laundry,
showers or garden watering systems, or can be accessed
manually via a tap for other outdoor uses such as car washing.
Treatment of rainwater for these uses is generally minimal.
The ACTC, as part of the larger Armstrong Creek Urban Growth
Area (ACUGA) will deliver best practice in water re-use through
mandated connection to third pipe (recycled water) reticulation.
Green roofs are partially or completely covered with vegetation.
The vegetation slows and reduces stormwater runoff. They can
also regulate internal building temperature by reducing heat
retention and acting as insulation.
Greywater is wastewater from washing machines, showers,
basins and taps (except the kitchen tap). Greywater can be reused outdoors as well as indoors for toilet flushing and clothes
washing.
Blackwater, or sewage, is wastewater from toilet fixtures. Reuse
of black water after on-site treatment is generally only permissible
outdoors for subsurface irrigation. On-site systems must be
approved by EPA Victoria.
Recycled water reticulation is the use of recycled water from
an off-site large scale water treatment facility. This requires two
sets of pipes - one for drinking water and one for recycled water
– to be connected to the development. The recycled water pipe
is connected to toilet, garden and outdoor uses. Due to the
requirement of an additional pipe this option is mainly suited to
greenfield sites.
The availability of Class A recycled water to the town centre
makes investment in other water reuse infrastructure (such as onsite grey water and black water recycling) largely redundant.
Case Study
Ecovillage at Currumbin, a residential subdivision close to the
Gold Coast, has established itself as a leader in many aspects
of sustainable water management. The site’s over arching aims
to become water self-sufficient and to be disconnected from
both water supply and sewerage networks have been achieved.
With around 70 houses now built and occupied, a combination
of highly efficient fixtures, appliances and landscaping, rainwater
collection and reuse and on-site blackwater treatment and reuse
has meant that residents avoid paying any of the standard water
authority supply and sewerage charges.

Rainwater
collection and
reuse
‘Fit for use’ water – Rainwater
can replace potable water in
many applications, including
toilet flushing, clothes washing
and irrigation.
Water balance – Capture
and usage levels must
be determined to ensure
the appropriate level of
infrastructure provision, given
the availability of 3rd pipe
reticulation.
Planning tools
• PSP and design guidelines to mandate 3rd
pipe connection to all buildings.
• Design Guidelines or Sustainability Rating
Tools to mandate rainwater collection and
tank capacity where appropriate. Refer to
STORM tool for guidance on appropriate
tank sizing.
Council leadership
• Council to determine feasibility of communal
rainwater collection from assets to augment
supply to swimming pool.
Large commercial buildings,
in particular (eg supermarkets
and restricted retail) will have
significant rain harvesting
potential.
On-site
Greywater
treatment and
usage
Reusing treated grey water for
toilet flushing can save around
50L of potable water and about
90L for washing machines in
an average household per day.
Context: Since introduction of
water restrictions, greywater
has become commonly reused
by individual dwellings (often
without treatment) for garden
watering hence has high
community acceptance levels.
Not applicable to ACTC
Blackwater
treatment and
usage
Treatment and usage of
blackwater can offset water
used for all toilet flushing and
landscape irrigation.
In the 60 L building,
blackwater is successively
treated by sedimentation
and digestion, bio-filtration,
and then clarification, after
which it undergoes a separate
two-stage filtration and UV
sterilisation process.
Context – Benefit of on-site
grey-water treatment may
be reduced by availability of
Class A recycled water which
recycles grey-water on a
commercial scale.
Not applicable to ACTC
Recycled water
reticulation
(third pipe)
A ‘third pipe’ system provides
for the optimal use of recycled
water from on-site, near-site
or large recycling facilities, and
can replace potable water for
the majority of toilet flushing
and irrigation needs, and may
be suitable for laundry use.
Context – well supported
by previous studies for the
Armstrong Creek, with capacity
to upgrade the existing Black
Rock facility as part of the
overall Armstrong Creek
growth area development
Suitability – Particularly
suitable for medium and higher
density applications where
limited rain and storm water
collection opportunities exist.
Detail design - Need to ensure
that recycled water does not
compromise warranties on
water products.
Planning tools
• PSP and design guidelines to mandate 3rd
pipe connection to all buildings.
• Design guidelines to mandate connections
of 3rd pipe to all fittings / appliance where
non-potable water is deemed appropriate.

Stormwater management
Introduction
Stormwater negatively impacts on receiving environments by
transporting gross pollutants, suspended solids, nutrients and
heavy metals to waterways. It can also cause localised flooding
and other environmental damage.
A combination of various techniques can be utilised to achieve
improved stormwater management.
Key concepts for stormwater management
Armstrong Creek Town Centre Context
Infiltration trenches, swales and litter traps collect and
filter stormwater by diverting water through vegetated filtration
systems. These systems are typically used on the side of
the roads and footpaths and can be retrofitted to existing
developments.
Dense urban centres can create significant storm water runoff due to highly impermeable surfaces such as car parks and
building roofs.
Bio-retention systems, or rain gardens, are landscape features
that collect the rain and slow down its movement. These can
be created using vegetated or paved areas, or a combination of
both.
Porous surfaces allow for stormwater to seep into the ground
gradually, reducing the volume of water flowing into drainage
systems, resulting in less drainage blockages during heavy
rainfall.
Constructed wetlands, streams and lakes can be used to
capture excess stormwater. Infiltration swales and bio-retention
systems are often connected to such areas either using existing
topology or conventional piping.
Rainwater tanks assist in reducing stormwater runoff volumes
during rainfall events, by providing temporary storage and delayed
release, and can reduce incidence of localised flooding.
Green roofs are partially or completely covered with vegetation.
The vegetation slows and reduces stormwater runoff. They also
regulate internal building temperature by reducing heat retention
and acting as insulation. This benefit is discussed in the Zero
Carbon section.
The strategy for ACTC includes a commitment to retain
stormwater back to pre-development levels and to use a series
of above ground and below ground retention basins / tanks and
WSUD treatments to treat and retain stormwater flows. Further,
the PSP will set caps on impervious surfaces to increase natural
stormwater seepage.
Case Study
The Coburg stormwater harvesting project - to be delivered
in Melbourne’s inner-north as part of the urban regeneration
project The Coburg Initiative - is a partnership project between
Yarra Valley Water, Moreland City Council and Melbourne Water.
The project will harvest stormwater from two existing drains,
transferring the water to a large underground tank before treating
the water on-site and distributing it around the precinct for use for
flushing toilets, washing clothes and irrigating open space.
The project will have a major impact on the water use of the
current and future development of the precinct and is expected
to save up to 213 million litres of drinking water each year
and significantly reduce pollution of the nearby Merri Creek
by reducing nutrients, litter and flow volumes associated with
stormwater runoff.

Sustainable Environmental
urban
performance
development
Introduction
Being able to measure environmental performance against key
indicators assists greatly in ensuring that a vision for environmental
sustainability can be delivered on the ground. Sustainability
rating tools are the key mechanism for measuring environmental
performance in buildings and precincts.
Sustainability rating tools
Sustainable ratings tools:
• Comprise a number of categories of environmental impact
• Set standards to measure the sustainability of a building or
precinct across defined categories
• Often target specific development types (e.g. residential
developments or precincts) or particular categories (e.g.
water), however it is common for different tools to evaluate
the same key indicators
• Present results in terms of a rating or a score that measures
a building’s level of sustainability.
Compliance with a particular tool is a simple way to indicate
targets, as tools have targets built into them. The use of
tools avoids the need for Council to undertake independent
research to identify and to justify their own targets, however
delivery of a precinct over an extended timeframe will need
to be flexible enough to change as standards improve and to
build in resilience for yet to be developed tools to be used to
demonstrate compliance with objectives.
An analysis of the current suite of available sustainability ratings
tools is outlined below. The analysis relies heavily on research
undertaken to support the MAV Planning for Sustainable
Buildings Guide.

Based primarily on the concept
of ecological footprinting,
the aim of the framework
is to provide a broad range
assessment of existing or
future buildings or communities
against the ten one planet
principles:
• Zero Carbon
• Zero Waste
• Sustainable Transport
• Sustainable Materials
• Local and sustainable food
• Sustainable Water
• Land Use and Wildlife
• Culture and Community
• Equity and Local Economy
• Health and happiness
The principles provide a
framework for examination of
sustainability challenges and
assist in the development of
action plans to live within a fair
share of the Earth’s resources.
Projects that develop a
detailed One Planet Action
Plan, outlining measures and
committments in line with
the ‘One Planet Common
International Targets to 2020’,
can apply for endorsement.
This involves assessment by
an approved representative
of BioRegional and final
endorsement by BioRegional’s
One Planet Steering Group.
•
• Formal endorsement is reserved
for those projects demonstrating
true international best practice,
so committments to achieve
endorsement can be significant.
• Logistically difficult to apply
across multiple landowners with
differing commitment levels to

Council leadership
The City of Greater Geelong has been an important advocate for the development of the
Armstrong Creek Growth Area to be underpinned by strong principles of environmental
sustainability. As a critical part of this growth area, the Town Centre, moves closer to detailed
planning, design and delivery, Council’s leadership and advocacy will continue to be vital.
Opportunities exist for Council to lead by example. for example by committing to delivery
of best-practice sustainability measures in its own facilities at the site. However its role as a
facilitator will be just as vital.
Innovative sustainability measures are often challenging at the precinct scale. However, some of
the biggest challenges may be overcome by little more than a proactive facilitator to bringing a
number of key parties together. An exciting opportunity exists for the City of Greater Geelong to
proactively bring key stakeholders together and find ways to deliver a ‘showcase’ of sustainable
town centre development. This table summarises the key opportunities for Council to both lead
and facilitate innovative sustainable outcomes for the project.
Principle
Zero carbon
Zero waste
Summary of strategies
• All Council facilities to be delivered in line with best practice thermal performance.
• Consideration of innovative measures, such as green roofs and walls in the design of
Council facilities.
• Council to invest in advanced Building Management Systems (BMS) for its own assets and
assist in developing the business case for other commercial developers to follow their lead.
• All public realm lighting to be delivered in line with current best practice standards. Higher
upfront costs are offset by energy savings and lower maintenance costs.
• Develop a procurement strategy for public lighting that addresses current market and
regulatory opportunities and constraints.
• Utilise solar hot water systems in all Council facilities.
• Council facilities to incorporate PV systems wherever practical.
• Work with supermarket operators to undertake pre-feasibility study to determine likely
suitability of a small waste to energy facility in the town centre using waste from the
supermarkets.
• Facilitate the development a pre-feasibility study for a range of on-site energy generation
scenarios, including central services hub, multi building or single building approaches.
If strong business case, engage with potential 3rd party operators (Energy Services
Companies), and commit council facilities to connecting to a future network.
• Explore regulatory mechanisms to require connection of buildings to local micro-grid.
• Explore nearby renewable energy resources for potential sites for a ‘project attributable’
renewable energy installation.
• Explore opportunities to link with existing community groups with an interest in local
renewable energy projects.
• Power purchase agreement with key tenants and/or local ESCo may be critical to feasibility.
• Opportunity for CoGG to demonstrate willingness to develop detailed plans for green
procurement for large development.
• Precinct level waste management plan developed to map resource flows and identify
opportunities for recovery.
• Instigate business case study for precinct wide vacuum collection system.
• Where new below ground infrastructure is being laid, precinct-wide vacuum waste collection
may be feasible if coordinated with other infrastructure delivery.
• Instigate business case study for waste to energy plant.
• Consideration of new or upgraded to regional resource recovery centre to service Armstrong
Creek Growth Area.
• Investigate opportunities for non-standard recycling services within the ACTC. Strong
potential to be incorporated into a community building (e.g. community leisure centre).
• Council to investigate options for differential pricing of different waste types through
municipal collections

summary
Landowner leadership and stakeholder collaboration
The Armstrong Creek Town Centre Precinct Structure Plan and associated planning tools will
provide direction to guide the development of this new urban area. The planning framework
provides important certainty and clarity on key issues to the local government, land owners,
developers and other stakeholders. There are, however, a range of issues and opportunities that
are currently not suited to mandatory consideration through formal planning tools and processes.
A range of the most innovative sustainability opportunities that have strong potential for
implementation at Armstrong Creek Town Centre fall into this category. Successful delivery
of these opportunities, including exciting initiatives such as precinct-scale low carbon energy
generation, and new approaches to efficient waste management, will therefore be reliant on the
initiative and cooperation of land owners, key stakeholders and the City of Greater Geelong.
The table below summarises the key strategies to be undertaken by land owners and other key
stakeholders to capitalise on the broad range of opportunities to deliver leading environmental
sustainability outcomes at Armstrong Creek Town Centre.
Principle
Zero carbon
Summary of strategies
• Prominent buildings and early projects to set benchmark for high passive performance
standards. For the supermarkets, this could include the development of ‘showcase’ stores in
line with stated company aims of demonstrating leadership in sustainable operations.
• Potential to facilitate bulk-buy of energy efficient appliances for commercial and residential
fitouts to reduce the small cost increases over standard appliances. The Place Manger
would provide important support.
• Consider light coloured covering for large exposed car parks. Potential to be fitted with PV
and form short term electric vehicle charging stations.
• Consideration of use of green roofs and walls in suited developments. Early commercial
developments encouraged to explore opportunities to use these as design features and link
to branding strategy.
• Advanced BMS design and commissioning approaches strongly encouraged for retail and
commercial buildings.
• Require large roof area buildings to make unutilised roof space available for rent for
aggregated solar array (at reasonable rate).
• Commercial tenants may be attracted to a leasing approach, reducing upfront capital and
realising savings during ongoing operation.
• Micro wind turbines may be appropriate for roofs of retail and office buildings, work with key
developers to identify opportunity for demonstration installation.
• If strong business case is present, obtain commitment of supermarkets to work with a 3rd
party operator to provide waste to, and purchase energy from, an on-site waste to energy
plant.
• Work with key commercial operators to lock in power purchase arrangements, to provide
greatest degree of certainty on future demand.
• Aquatic centre precinct, early retail/office/supermarket development may be appropriate as
catalyst customers.
Zero waste
• Work with supermarkets and other key landowners to ensure future connection to a
precinct-wide collection system.
• Work with supermarkets and other key landowners to understand potential waste stream
that a waste to energy facility could process.
