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.
