5.16 Environmentally Sustainable Development
Sustainability is a core consideration in the development of Walk Up Village and the scheme
has been designed to meet or surpass a series of rigorous environmental benchmarks, in doing
so providing tangible benefits to tenants and the wider community and ensuring the scheme’s
impact on the environment is minimised. International Environmental and Sustainable Design
Engineer Atelier Ten has developed a Sustainable Management Plan (SMP) which details the
proposal’s approach to sustainability and is summarised below.
Sustainable Management
The project uses the Green Star 5 Star Design & As-Built v1.2 standards as a quality
assurance methodology to deliver a design that represents excellence in sustainability. All
key environmental building systems will follow Green Star best practice guidelines regarding
design, commissioning and testing.
The project has adopted specific, best practice environmental management procedures
which will be implemented during construction and operational performance targets to
minimise greenhouse gas emissions, potable water consumption, waste and improve indoor
environmental quality. The project has been designed to facilitate easy, careful management
of energy and water consumption for its end users. The project will aspire to achieve a high
NABERS rating (consistent with all of Molonglo’s projects) for office areas and implement a
smart metering system that makes visible and helps minimise the running costs and impacts.
Energy & Greenhouse Gas Emissions
Robust, simple and easy to operate passive systems will minimise the energy requirements of
ventilation, heating and cooling. Passive systems include supplemental natural ventilation, solar
shading provided by the concrete finned facade, high-performance building fabric and glazing,
and slab edges capped with insulation to avoid thermal bridging and allowing for the utilisation
of exposed internal finishes for thermal benefits. High efficiency heating and cooling systems
and LED lighting throughout will further minimise energy use.
A photovoltaic (PV) array utilises the north-facing sawtooth roof profiles and will support
onsite energy generation with its output providing a significant contribution towards base
building energy demands without drawing from the grid. Almost all weekend energy
requirements can be supported by the PV array alone. The building will incorporate allowances
to transition to a ‘gas-free’ servicing strategy in the future, to be implemented once the national
electrical grid is de-carbonised below the emissions of onsite gas usage.

Indoor Environmental Quality
The project will provide a high-quality indoor environment above and beyond that defined
by Green Star best practice benchmarks, supported by high levels of mechanical fresh air
supply and air flow, and openable windows for personal comfort. Façade performance has
been modelled and optimised to balance annual thermal energy requirements, good daylight
penetration, solar heat gain, glare and views out across the city. The project will achieve
excellent levels of indoor daylight provision and will meet the minimum daylight provisions of
WELL standards if future developments enclose the building on neighbouring plots.
Water Management
The project utilises rainwater harvesting for irrigation to all garden areas and will comply
with Water Sensitive Urban Design objectives set out in the City of Yarra planning scheme. A
6,000L irrigation tank stores rainfall and raingardens will attenuate storm water runoff. Garden
spaces will utilise low maintenance and drought resistant species where possible to reduce
water demand, and cooling systems will incorporate air-cooled condensers rather that cooling
towers to significantly reduce the use of potable water.
Materials Management
Material selection and sourcing within the development will be undertaken with sustainable
development principles in mind. This will include the use of low-carbon cement substitutes and
recycled aggregates wherever possible, certified sustainable and responsible sourcing of timber
and other products, and a waste-to-landfill target during construction of under 10%. Materials
will be chosen to age and patinate allowing for longevity.
Land Use & Ecology
The project re-uses an existing brown-field site and will provide significant ecological benefits.
Native or locally adapted plant species will promote biodiversity and will be grown in all
garden spaces. Generous soil trenches throughout will support dense plant coverage that will
considerably improve the ecology of the site by creating an improved habitat for birds and
insects.
The thermal mass of soil trenches will moderate the indoor environmental quality of adjacent
tenancies and will reduce the urban heat island effect when combined with the use of high-
albedo (light coloured) external surfaces. Similar green roofscapes have been shown to reduce
surface temperatures by 15 - 20 oC on hot days.
Sustainable Community
A vibrant, active and healthy community will be created through the dynamic tenancy strategy,
supported by street level activation and publicly accessible vertical circulation through the
garden stair ravine. Carefully designed garden spaces are distributed throughout the scheme
and will be publicly accessible, providing restorative outdoor areas that nurture community
interaction, health and wellbeing, and encourage meaningful contact with nature.
Transport and Access
One Mile Grid’s Green Travel Plan (outlined in chapter 2.5 Transport Connections) concludes
that the site is extremely well connected and consequently suggests a sustainable transport
strategy for the building summarised below.
Car Parking and Vehicular Access
Primary access will be provided by the laneway along the site’s southern boundary, linking
to a one-lane ramp and single-level basement, widened to provide for two-way traffic at the
interface with Rupert Street.
The basement will accommodate 40 parking spaces, including three accessible spaces, two
spaces dedicated for electric vehicle charging, and two additional spaces for use exclusively by
on-site share cars, supplied and managed by the operator.
Pedestrian and Cycle Access
Primary pedestrian access to the site will be provided from the Rupert Street frontage, via the
garden stair ravine which extends vertically through the building. Cycling facilities, including
parking and end-of-trip facilities are also accessed from the ravine.
Bicycle Parking
A total of 218 bicycle parking spaces are to be provided on the ground floor and mezzanine,
and will be made available to employees and visitors of the use. These will be supplemented
by 12 shower and changing rooms and associated lockers on the ground floor for staff as well
as bike maintenance and a cycle coffee culture similar to the applicant’s Godspeed Bicycle Co.
project in Canberra.
Loading & Waste Collection
All loading and waste collection needs will be accommodated within a dedicated secure
and safe loading dock, accessed from Rupert Street. The loading dock has been designed to
facilitate access vehicles up to 8.8 metres length (medium rigid vehicles).

5.18 Conclusion
Walk Up Village will be a new kind of building that combines a radical mix of cultural, social
and commercial uses with generous open space. It has been designed following extensive
research, public and professional consultation and a thorough review of strategic and economic
policy aims.
The building’s design has emerged from an understanding of the historic and emerging
architecture of Collingwood, aspiring to help the areas retain its diverse community and
importance as a creative and productive centre.
The proposal has a unique model that integrates public landscape with workspace, commerce
and charitable activity to grow a sustainable community. Its architecture responds to this model
with proposals that build upon the fine-grained urban scale of Collingwood and the everyday
materiality of its streets and buildings. It is carefully massed to respect its neighbours, both
current and future, whilst delivering meaningful community benefit and opening its borders;
improving the public realm and welcoming the broadest constituency.
