Sustainable design

Depending on the size of development proposed, either a Sustainable Design Assessment (SDA) or a Sustainability Management Plan (SMP) is required. (Refer to Table 1 above). A Stormwater Management Assessment (SMA) can be submitted in response to stormwater management (WSUD) requirements.

Sustainable Design Assessment (SDA)

An SDA is a simple sustainability assessment of a proposed building at the planning stage that demonstrates best practice in ESD performance. The content demonstrates how your proposed development addresses the 10 sustainable building categories.

Our Sustainable Design Assessment template (DOCX 132 KB) provides an indication of the information you need to submit.

Sustainability Management Plan (SMP)

An SMP is a detailed sustainability assessment of a proposed building at the planning stage that demonstrates best practice in ESD performance. The content demonstrates how your proposed development address the 10 sustainable building categories.

Preparation of a Sustainability Management Plan will generally require the engagement of a sustainability consultant.

Stormwater Management Assessment (SMA)

An SMA addresses the Water Sensitive Urban Design requirements of the Stormwater Management Policy, Clause 22.12 of the Port Phillip Planning Scheme. This can either be a stand-alone report or it can be included within an SDA or SMP.

The SMA content will include a:

• description of proposed stormwater treatment devices
• stormwater quality report using the STORM or MUSIC tools
• stormwater site layout plan showing catchment area, treatment devices and any permeable surfaces
• maintenance program for the treatment devices
• stormwater construction site management plan.

Stormwater management during construction should address these key considerations:

• protection measures for stormwater drains surrounding the site
• direction of roof run-off to drains and bunded areas
• location of wash-down areas on site
• stockpile protection such as using tarps
• use of rumble strips at site vehicle access points to keep mud off roads
• litter containment measures on site.

Our Compliance Guidelines for Clause 22.12 Stormwater Management (PDF 1.5MB) explains how to put together the SMA and contains useful examples such as site management plans and design detail drawings.

ESD Implementation Report

The ESD Implementation Report is submitted to Council as the development is nearing completion, prior to occupancy. The report demonstrates how the ESD features have been implemented on site, providing evidence that the commitments in the endorsed Sustainable Design Assessment (SDA) or endorsed Sustainability Management Plan (SMP) have been met.

Our template ESD Implementation Report (DOCX 157 KB) can be used for this purpose. It is based on the Built Environment Sustainability Scorecard (BESS) but can be adapted to suit the method of assessment in your SDA/SMP. For assistance with this template, please contact our Sustainable Design Advisors.

A report from an ESD assessment tool should be appended to your main ESD report. These tools provide an assessment of your proposal against an established rating system.

Some ESD assessment tools assess a broad range of ESD categories, while others focus only on a single component of ESD, such as stormwater quality or energy efficiency.

A more detailed overview is provided in our ESD Tools Factsheet (PDF 486 KB).

Built Environment Sustainability Scorecard (BESS)

The Built Environment Sustainability Scorecard (BESS) is an online ESD assessment tool purpose-built for the planning application stage. It assesses nine ESD categories and is suitable for almost all development types including:

• single dwellings
• dwelling extensions
• multi-dwellings
• non-residential
• mixed use.

A BESS score of 50 per cent indicates a 'Pass', while a score of 70 per cent or greater indicates 'Excellence'.

There are four mandatory categories which must be passed:

• energy
• water
• stormwater
• indoor environmental quality.

Additional score points can be gained from other categories including:

• waste
• transport
• urban ecology
• management

Green Factor

Green Factor is a green infrastructure assessment tool that is free to use and available for most development types and scales.

A Green Factor assessment considers the different types of green infrastructure within a development proposal, such as trees in ground, on-structure planters and vegetation, green facades and green roofs.

The tool takes account of the environmental benefits, such as urban cooling and habitat creation, and broader social benefits. The resulting score indicates a site’s proposed green factor. During our current trial of the Green Factor tool, while there is no mandatory requirement, the following scores are recommended as demonstrating a reasonable outcome for urban greening:

On the Green Factor Tool website, click ‘Start Assessing New Site’ button and it will take you to the ‘Locate your site page’ where you can select the City of Port Phillip from ‘Select a Local Government Area’ drop down list.

From there you can click the ‘Start Assessment’ tab and begin your Green Factor Tool assessment.

BESS Innovation Credit

Council will consider 1 Innovation credit for developments which integrate the Green Factor tool assessment with their planning submission. Under the Innovation category provide the following information:

Green Star

Green Star is the Green Building Council of Australia’s certification system. Their Design and As Built rating tool assesses a broad range of ESD categories and is suitable for assessing large-scale developments. Reliance on operational commitments to gain a Green Star benchmarked rating will not be accepted at planning stage.

STORM

STORM assesses stormwater quality outcomes for small to medium-scale developments, as part of an SMA. It's available online for free and managed by Melbourne Water. A minimum score of 100 per cent is required to demonstrate best practice stormwater management.

MUSIC

MUSIC is a detailed stormwater modelling software that is available for purchase from eWater. It's suitable for assessing stormwater treatment for medium to large-scale developments.

FirstRate5

FirstRate5 assesses residential energy efficiency for the building envelope only.

The software is most commonly used in Victoria to demonstrate compliance with the National Construction Code of Australia (NCC) energy efficiency requirements for residential buildings. It uses the Nationwide House Energy Rating Scheme (NatHERS) protocol, however, a 6-Star FirstRate energy rating does not reflect best practice energy efficiency for ESD.

A building’s orientation, glazing proportions and construction materials largely impact the rating. Many designers now use energy rating tools as design tools rather than as compliance tools.

We strongly recommended conducting a preliminary assessment before lodging your drawings for a planning permit. This can reduce the likelihood of having to apply to amend your planning permit if a later energy rating shows that you have to change the building design to meet minimum NCC standards.

An energy rating will have to be completed for most new dwellings and some extensions at the building permit stage at the latest.

Before submitting your application:

• consider sustainable design early and discuss it at your pre-application meeting
• access ESD advice for free by contacting our Sustainable Design team
• prepare your plans and ESD documents
• make clear commitments in your documentation and avoid vague language such as 'where practical' and 'as appropriate'
• ensure the design details on your plans are consistent with the ESD commitments in your documentation.

When submitting:

• Council’s Planning team will make a preliminary assessment
• Council’s Sustainable Design officer reviews your application
• the Sustainable Design officer will either confirm the submission is acceptable, or require sustainable design improvements.

Once a planning assessment outcome has been reached, ensure:

• The agreed ESD initiatives are reflected in the details on your endorsed plans and in your endorsed documentation such as the Sustainability Management Plan.
• An ESD Implementation Report (DOCX 157 KB) demonstrating how your ESD initiatives have been implemented is submitted to us upon completion of your development.

Our expectations for sustainable developments can be found in two stages:

• Planning stage: during design or planning you must demonstrate how your development's design addresses the 10 sustainable building categories.
• Building stage: during compliance and building you must provide an ESD Implementation Report to demonstrate how the ESD features of the design were successfully incorporated into the built outcome.

Planning stage

To demonstrate best practice in environmentally sustainable design, your development should incorporate the initiatives listed under each of the 10 sustainable building categories.

Note, a 'pass' score in BESS is a required element of an SDA and SMP, but the development must also achieve all the objectives under Clause 22.13 of the Port Phillip Planning Scheme.

Building stage

Your planning permit will include a condition that requires you to submit an ESD Implementation Report demonstrating how the ESD features of the design were successfully incorporated into the built outcome.

An acceptable ESD Implementation Report will be endorsed as part of your planning approval prior to building occupancy. The ESD Implementation Report will be written by the same author of the endorsed ESD documentation or a similarly qualified person who has been involved in the building stage of the project, such as an ESD consultant, architect or project manager.

The report will contain:

• a summary of the ESD initiatives that were approved during application
• details of where these initiatives have been installed in the building
• evidence of installation or implementation.

The report will contain a variety of evidence relative to the development type. This could include:

• energy ratings for apartments
• receipts for materials and fittings
• product specifications such as WELS ratings for taps
• photos of implemented initiatives, such as renewable energy systems, external shading to windows and installed rainwater tanks.

• Appropriate external shading to all windows receiving direct sunlight
• Adequate daylight to all habitable rooms including commercial spaces
• Effective natural ventilation including operable windows in all habitable rooms
• Low toxicity products used such as low VOC paints and adhesives

Our stormwater drains to Port Phillip Bay. As the intensity of urbanisation in our suburbs increases, so does the level of pollutants and debris in the water that reaches the bay.

WSUD minimises the impact of development on our waterways and water resources. Our Stormwater Management Policy at Clause 22.12 of the Planning Scheme requires planning applications to demonstrate how the proposed development incorporates best practice WSUD by submitting a Stormwater Management Assessment (SMA).

A rainwater tank that collects stormwater run-off from the roof and connects to toilets for flushing is a common WSUD measure for small-scale developments.

Other typical stormwater management features include raingardens (PDF 1.4 MB), porous paving (PDF 1.6 MB) and a mixture of different features on a single site.

Green walls and roofs, under the Urban Ecology sustainable building category, can also contribute to stormwater management.

Addressing the on-going maintenance of a stormwater treatment system is an application requirement.

Council has produced maintenance manuals for the three most common types of domestic stormwater management, which are free for applicants to use and submit for endorsement:

• Rainwater Tank Maintenance Manual (PDF 500 KB)
• Raingarden Maintenance Manual (PDF 1.4 MB)
• Porous Paving Maintenance Manuall (PDF 1.7 MB)

Managing stormwater run-off during construction is another important requirement of an SMA under Clause 22.12. To address these matters in your WSUD response:

• include a table detailing which measures will be implemented
• provide a simple site layout plan indicating where the measures will be located such as in Compliance Guidelines - page 28, Appendix C4, Figure 6, (PDF 1.2 MB) of the Planning Scheme. 

For more information, see Keeping Our Stormwater Clean: A Builder’s Guide.  This template Stormwater Site Management Plan can be used for your submission.

Specific Sustainable Design requirements for the Fishermans Bend Urban Renewal Area (FBURA) are written into the schedule to the Capital City Zone (CCZ1) and in the Fishermans Bend Urban Renewal Area local planning policy (Clause 22.15) of the Port Phillip Planning Scheme.

The requirements include:

• conditional requirements for all developments to achieve a certified Green Star rating.
• conditional rainwater tank and third pipe requirements.
• energy efficiency to exceed NCC by 20 per cent.
• renewable energy generation included on each site.
• a 70 per cent total site area comprising elements to reduce the urban heat island effect.
• building design for flood and sea level rise resilience.
• food and green waste collection opportunities included in each proposal.
• landscape design to incorporate flood mitigation and WSUD.
• provision of deep soil planting areas and green facades/rooftop planting.

These requirements apply in addition to the ESD and WSUD requirements applicable to the entire municipality (refer to Port Phillip Planning Scheme Clauses 22.12 and 22.13 respectively).

Developments in FBURA are required to register with the Green Building Council of Australia prior to commencement of development. A certified Green Star Design and As Built rating is required to be achieved within 12 months of building occupation.

Achieving a Green Star certified rating is a conditional requirement, dependent on building scale:

10 or more dwellings or 5,000m² or greater floor space = 5 star Design and As Built rating

All other buildings and works greater than 50m² = 4 star Design and As Built rating

At the planning application stage, an SMP should demonstrate how the relevant Green Star rating will be achieved, with a 10 per cent points buffer included, to provide contingency for unforeseen changes.

Refer to Innovative Sustainable Design for Large-Scale Developments (PDF 563 KB) for innovation considerations in FBURA.

Development Requirements

As Australia’s largest urban renewal project, Fishermans Bend presents a significant opportunity to achieve integrated water management outcomes in both the public and private realm.

All developments need to deliver:

• Provision of recycled water supply via third pipe for all non-potable water uses
• Rainwater capture from 100 per cent suitable roof areas including podiums
• Fit for purpose stormwater treatment for end uses
• Integration of green infrastructure

Collectively, the integrated water management components of a development reduce potable water demand, reduce peak stormwater flow for flood mitigation, improve stormwater quality and reduce urban heat island effect.

Case Studies

Case studies have been developed to assist planning applicants in responding to these requirements based on hypothetical development scenarios for common development typologies.

They provide a preferred and typical pathway to achieve the required integrated water management outcomes and policy compliance in the Fishermans Bend Urban Renewal Area.
