§ 02  ·  About

A Melbourne consultancy built around one idea: buildings that perform.

Based in Melbourne, Victoria, we're a building sustainability consultancy helping clients meet the National Construction Code while improving occupant comfort, running costs and long-term performance. We work with builders, architects, designers, developers, building surveyors and homeowners — providing practical advice and accurate assessments that support planning approvals and building permit applications.

Our mission

To provide accurate, practical and affordable sustainability consulting that helps create energy-efficient, compliant and environmentally responsible buildings — from single dwellings to multi-unit residential and commercial developments.

Using industry-recognised software including FirstRate5 and HERO, we prepare high-quality sustainability reports tailored to each project's requirements. Where a design doesn't hit the required rating, we come back with practical, cost-aware recommendations — not a rebuild.

§ 06  ·  FAQ

Frequently asked questions.

Straightforward answers to the questions we hear most from clients — before we get to the quote.

A NatHERS (Nationwide House Energy Rating Scheme) Energy Rating measures the thermal performance of a home — how efficiently it maintains comfortable indoor temperatures year-round — and demonstrates compliance with the energy efficiency requirements of the National Construction Code (NCC).
A rating is generally required when applying for a building permit for a new dwelling, or for alterations and additions that are subject to NCC energy efficiency requirements.
Typically: architectural plans, elevations, floor plans, sections, site plan, window and glazing schedules, and construction specifications for walls, roofs, floors and insulation.
Turnaround varies with project size and complexity. Most residential assessments are completed within a few business days once all required information has been received.
We provide practical recommendations to improve thermal performance — changes to glazing, insulation, shading, building materials or other design elements — keeping construction cost impact in mind.
Yes. We provide energy assessments for new homes, townhouses and apartments, as well as renovations, extensions and alterations where required.
An SDA is a report demonstrating how a development addresses sustainability objectives. Many Victorian councils require an SDA as part of the planning permit process for certain developments.
Projects throughout Victoria. We can assist clients remotely using electronic drawings and project documentation.
Pricing depends on project type, size and complexity. Send us your project details and we'll provide a competitive, obligation-free quotation.
Yes. We regularly work with builders, architects, building designers, draftspersons and building surveyors to ensure projects achieve compliance efficiently.
