Sustainable Design Assessment
Energy Assess delivers pragmatic Sustainable Design Assessment reports (SDA) that satisfy council requirements and keep projects moving in Victoria. For most residential developments with 3–9 dwellings and commercial projects of 500–1,000m² an SDA is mandatory for planning approval, and our Melbourne-based team ensures the process is clear, fast, and cost-effective while aligning with NatHERS and other regulatory requirements.
We translate planning needs into actionable design outcomes so builders, architects, developers, and homeowners can secure approvals, control costs, and deliver comfortable, efficient buildings. We structure every Sustainable Design Assessment report to your council’s template and evidence standards for a smooth assessment process.
What your Sustainable Design Assessment covers
We begin every project with a thorough review of your architectural plans and specifications. Our Sustainable Design Assessment framework covers a number of key performance areas, including:
- Energy Efficiency: We analyse building orientation, insulation, glazing performance, and shading to minimise energy consumption for heating and cooling.
- Water Conservation: Our evaluation includes strategies for efficient water fixtures, rainwater harvesting, and water-sensitive landscaping to reduce mains water usage.
- Indoor Environment Quality (IEQ): We assess factors like access to natural light, ventilation, and the use of low-toxicity materials to create healthier and more comfortable indoor spaces for future occupants.
- Stormwater Management: We analyse the proposed methods for stormwater treatment and runoff reduction, ensuring your project positively contributes to the local water cycle.
Leveraging Industry-Standard Tools for Success
To deliver a robust and defensible Sustainable Design Assessment, our process incorporates industry-leading tools like the Built Environment Sustainability Scorecard (BESS). BESS provides a standardised method for assessing the sustainability performance of a project against a broad range of benchmarks.
As part of your SDA report, the Energy Assess team may conduct a preliminary energy report or generate a NatHERS certificate (Nationwide House Energy Rating Scheme). These detailed reports are vital when we assess a building’s thermal performance, providing concrete evidence that your design meets the specific energy efficiency targets required by the planning permit. Our approach ensures that every claim in your report is backed by credible, verifiable data.
Practical, Cost-effective Recommendations
We focus on solutions that work the first time. We pride ourselves on being able to identify the most cost-effective measures to meet council’s targets with minimal rework – prioritising fabric improvements and passive design before proposing higher-cost systems. Our advice is in plain English with clear actions, product or specification guidance where appropriate, and a documented pathway to compliance. Expect quicker council feedback, fewer RFIs, and a smoother road to your planning permit.
