Sustainability Assessment Plan

Our Sustainability Assessment Plan (SAP) refers to the inclusion of key environmental performance considerations at Development Approval stage in order to meet planning requirements set by State and Local Government. This Plan acts as your guide to achieving more sustainable building outcomes for the long-term benefit of occupants, and differentiates your product and brand from the competition. Importantly, the developer and local council know exactly ‘what’ Environmentally Sustainable Development (ESD) considerations are included and ‘how’ they will be delivered.

Ideally suited to multi-unit residential development, our Sustainability Assessment Plan (SAP) can also be used for smaller developments to help guide decision makers and local council, ensuring all parties are ‘on the same page’.

Our Plan is an affordable, simple, yet effective sustainability assessment of your proposed design to support your planning application by showing how you intend to address Key Sustainable Building Categories – meeting and/or exceeding requirements.

While Council’s Planning Scheme outlines general sustainable design requirements, we encourage you to strive for best practice, creativity and innovation.

Changes Effecting New Development

Design WA – State Planning Policy 7.3 – Residential Design Codes Volume 2 – Apartments

Introduced on 24 May 2019, all applications for multi-unit development approval in Western Australia (R40+) now need to demonstrate achievement of design objectives for all 10 Design Elements under Design WA. This new policy is a performance-based policy.

While addressing the Acceptable Outcomes is likely to achieve the Objectives, they are not a deemed-to-comply pathway and the proposal will be assessed in context of the entire design solution to ensure the Objectives are achieved. Proposals may also satisfy the Objectives via alternative means or solutions. (Source: Design WA)

Local Government Planning Policy

Each Local Government has their own Environmentally Sustainable Development (ESD) requirements that complement or improve upon the Western Australian Planning Commission ‘Design WA’ Policy. Not all Councils have the same Planning Policy for the built-form so it pays to research and collaborate with them to ensure you make the right choices using our experience, first time round. This is part of our service.

Example, the City of Vincent Built Form Policy 1.8 requires that at a minimum the Global Warming Potential (GWP) of the development over its lifetime is to be reduced by 50% or more when compared to the average Australian code-compliant equivalent building built at the same time, and Water use of the development over its lifetime be reduced by 25% or more.

How We Help You

We assess the opportunities for your development, combined with a Life Cycle Assessment (required by many Local Councils as a measurement of performance) to demonstrate how your project meets Council standards for sustainable design. We provide a description of how the project intends to respond to each of the 10 categories, demonstrated through building and landscape design drawings.

What is Life Cycle Design

A Life Cycle Assessment (LCA) seeks to quantify and improve design and optimise building performance according to international standards ISO14044 and EN15978 calculation method. LCA is a method used to determine the real cost and environmental impact of a product over its life and accounts for impacts and costs from cradle to grave. LCA of the built form involves quantifying the total “Embodied” and “Operational” impacts over the design life of the building.

This life cycle design approach compares the life cycle impacts of design options to a chosen benchmark. Recommendations are made to reduce the impacts of the design while balancing the trade off between embedded and operational impacts.

CP Collaborative – 10 ESD Categories

1.0 Indoor Environment Quality

Objective: to achieve a healthy indoor environment quality for the wellbeing of building occupants.

Examples of design decisions: daylight/ thermal comfort/ natural ventilation/ VOC’s.

2.0 Energy Efficiency & GHG Reductions

Objective: to ensure the efficient use of energy, to reduce total operating greenhouse emissions and to reduce energy peak demand.

Examples of design decisions: thermal performance (NatHERS)/ Life Cycle Assessment/ Hot Water/ Appliances/ Lighting/ Renewables (Solar)/ Behavioural Management

3.0 Water Efficiency

Objective: to ensure the efficient use of water, to reduce total operating potable water use and to encourage the appropriate use of alternative water sources.

Examples of design decisions: use efficient fixtures and fittings/ avoid the use of mains water for landscape irrigation/ re–use water (e.g. greywater)/ water-wise specie choice

4.0 Building Materials (Built Form)

Objective: to minimise the environmental impacts of materials used by encouraging the use of materials with a favourable lifecycle assessment:

Examples of design decisions: embodied energy of materials/ use of materials with recycled content/ future recyclability of materials.

5.0 Transport

Objective: to minimise car dependency and to ensure that the built environment is designed to promote the use of public transport, walking and cycling.

Examples of design decisions: providing convenient and secure bike storage/ providing access to showers and lockers at work/ Sustainable Transport and travel plan options for residents and visitors/ EV recharge stations

6.0 Waste Management

Objective: to ensure waste avoidance reuse and recycling during the construction and operation stages of development.

Examples of design decisions: preparation of a construction Waste Management Plan/ adoption of a demolition and construction material recycling target/ preparation of an operation Waste Management Plan through Residential Waste Avoidance and Minimisation Plan (RWAM).

7.0 Urban Ecology

Objective: to protect and enhance biodiversity and to encourage the planting of indigenous and edible vegetation.

Examples of design decisions: maintaining / enhancing the site’s ecological value/ creating resident amenity/ encourage biodiversity areas/ productive gardens/ education planning.

8.0 Sustainable Lifestyle: Green Living Program

Objective: to encourage and empower residents within the development to live sustainable lifestyles.

Examples of design decisions: Green Living Program/ Sustainability management committee.

9.0 Construction and Building Management

Objectives: to encourage a holistic and integrated design and construction process and ongoing high performance.

Examples of design decisions: Building Users Guide that explains a building’s sustainable design principles/ preparation of operational Environmental Management Plan.

10.0 Community

Objectives: To ensure the project adequately supports ongoing community cohesion and resilience as a socially sustainable community.

Examples: Community Engagement/ Quality pubic realm/ connected communities/ safe & accessible living design/ Internet.
