Request a quoteThe Green Building Council of Australia (GBCA) is the nation's authority on sustainable buildings, developing and operating the Green Star rating system: Australia's leading framework for the design, construction, and operation of sustainable buildings and communities.
Ark Resources has been a member of the GBCA and an accredited Green Star professional practice for over 15 years. Over that time, our team has delivered Green Star assessments and certifications across a wide range of commercial and residential projects, helping clients achieve measurable sustainability outcomes that are independently verified.
Vincent Logarzo is a technical expert to the GBCA under the Green Star Homes Rating tool, contributing to the initial cost-benefit analysis of this standard. This direct involvement reflects the depth of technical knowledge Ark Resources brings to every Green Star engagement.

The Green Building Council of Australia is the nation's authority on sustainable buildings, operating the Green Star rating system. Green Star certifications recognise buildings and communities that are designed, built, and operated to the highest sustainability standards.

Energy Modelling Services →Residential Credits
NatHERS Thermal Performance
NatHERS star band ratings for residential projects seeking Green Star Homes certification across all dwelling types.
NatHERS Services →NABERS Embodied Carbon Rating
All new Green Star Buildings registrations now require higher quality and scrutiny on embodied carbon. Like LCA, an independent peer review process governs its delivery, utilising the NABERS Embodied Carbon Rating rules.
We see these changes as a real inflection point toward a more sustainable and transparent built environment.
Our team includes two NABERS embodied carbon assessors, providing:
Independent peer review over embodied carbon reports prepared by your design team
Design team member providing advice over material selections and scenarios combining your trade partners proposed materials
A NABERS Embodied Carbon rating is an independently audited, certified metric you can use directly in project marketing, ESG disclosures, GRESB reporting, and investor communications. Unlike design stage estimates, it is a verified number that holds up to scrutiny, giving your sustainability claims a level of credibility that resonates with institutional investors, government procurement panels, and future tenants.
Green Star FAQs
What is Green Star and who administers it?
Green Star is Australia's leading green building rating system, administered by the Green Building Council of Australia (GBCA). It provides independent third-party certification of a building's sustainability performance across categories including energy, water, indoor environment quality, materials, transport and innovation. Green Star ratings range from 4 Star (Best Practice) to 6 Star (World Leadership).
Which Green Star rating tool should I use?
The appropriate Green Star tool depends on your building type and project stage. Green Star Buildings applies to most new commercial, residential and mixed-use buildings. Green Star Performance applies to existing buildings in operation. Ark Resources can advise on the most suitable pathway for your project.
How early should I engage a Green Star consultant?
As early as possible, ideally at concept design stage. Green Star credits influence design decisions around orientation, glazing, materials, systems and contractor selection. Early engagement allows Ark Resources to maximise your achievable rating without costly late-stage design changes. We can also assist with target rating analysis during feasibility.
What does Ark Resources do as a Green Star consultant?
Ark Resources provides end-to-end Green Star consulting: target rating analysis, credit strategy, documentation coordination, GBCA submission preparation, and post-registration credit management. We work closely with your architect, services engineers and contractor to gather and verify credit evidence throughout the project lifecycle.
What changed in the latest Green Star Buildings version?
The latest Green Star Buildings version introduced updated requirements including mandatory electrification pathways, embodied carbon reporting, enhanced indoor environment quality requirements, and revised energy and water targets. Ark Resources can provide a gap analysis comparing your current design against the latest requirements.

Our Green Star team includes three Green Star Accredited Professionals covering rating strategy, technical modelling and certification management across all project types.
