ECBC Compliance

What is ECBC?

Building Energy Efficiency Certificates for commercial property

A Building Energy Efficiency Certificate (ECBC) is a mandatory requirement under the Building Energy Efficiency Disclosure (BEED) Act 2010 for commercial office buildings of 1,000 m² or more that are being sold, leased or subleased in Australia. A valid ECBC must be publicly registered on the Building Energy Efficiency Register (BEER) before a property can be marketed.

We manage the full ECBC process — from NABERS Energy rating to Tenancy Lighting Assessment — ensuring your certificate is accurate, compliant and registered without delay.

ECBC compliance assessment for commercial office building

ECBC Accredited Assessor

What's included

A complete ECBC compliance service

We handle every component of the ECBC — from energy data collection through to certificate registration on the BEER — so your property transaction isn't held up.

01

NABERS Energy rating

A current NABERS Energy rating (base building or whole building) is a core component of every ECBC. We are accredited NABERS assessors and manage the full rating process — collecting energy consumption data, verifying occupancy details and submitting the rating to the NABERS National Administrator.

02

Tenancy Lighting Assessment (TLA)

Every ECBC requires a Tenancy Lighting Assessment — a survey of the lighting installed in the building's tenancy areas, benchmarked against the maximum power density allowed under the BEED Act. We conduct the TLA on-site and prepare the required documentation for inclusion in the certificate.

03

BEER registration

Once the NABERS rating and TLA are complete, we compile and submit the ECBC to the Building Energy Efficiency Register (BEER) — the publicly accessible national register maintained by the Department of Climate Change, Energy, the Environment and Water. We confirm registration and provide you with the certificate details for your records.

04

Certificate renewal

ECBCs are valid for 12 months. If you hold an existing certificate approaching expiry — or if your property is to be re-listed or re-leased — we manage the renewal process, updating the NABERS rating and TLA as required and re-registering on the BEER ahead of your deadline.

05

Disclosure obligation advice

We advise on whether your building and transaction trigger disclosure obligations under the BEED Act — including coverage thresholds, exemptions and timing requirements — so you understand your obligations before going to market.

How it works

From data collection to registered certificate

A structured process built around your transaction timeline — we work to your settlement or lease dates.

01

Scope & eligibility check

We confirm whether your building and transaction are covered by the BEED Act, identify the correct NABERS rating type and establish the data collection period required.

02

Energy data collection

We collect 12 months of energy consumption data from your utility provider and building management system, verifying metering boundaries and occupancy figures.

03

On-site Tenancy Lighting Assessment

We conduct the TLA survey, recording installed lighting type, wattage and area coverage across all tenancy spaces in the building.

04

NABERS rating & ECBC registration

The NABERS rating is submitted and confirmed. We then compile the full ECBC and register it on the BEER — sending you confirmation of the certificate number and star rating.

FAQs

Common questions about ECBC compliance

Which buildings require a ECBC?

The BEED Act applies to commercial office buildings with a net lettable area of 1,000 m² or more that are being sold, leased or subleased. Mixed-use buildings are assessed on their office component. Some transactions are exempt — including leases of less than 12 months and buildings in certain remote locations. We can confirm whether your property and transaction are covered.

How long is a ECBC valid for?

A ECBC is valid for 12 months from the date it is registered on the Building Energy Efficiency Register. If a valid ECBC is already on the register for your building, it can be used for the transaction — but if it has expired, a new certificate must be obtained before the property can be advertised.

What NABERS star rating is required for a ECBC?

There is no minimum star rating required to obtain a ECBC — the certificate records whatever rating the building achieves. However, a low rating may affect market perceptions, and prospective tenants or buyers can view the registered rating publicly on the BEER. We can advise on practical steps to improve your building's rating ahead of a transaction.

How long does the ECBC process take?

Typically 3–4 weeks from the start of energy data collection to certificate registration, assuming data is readily available. If energy billing data needs to be requested from a utility provider, allow additional time. We recommend engaging us at least 6 weeks before your intended marketing date.

Can you help if we're the tenant, not the building owner?

Yes. Where a subtenant is subleasing space of 1,000 m² or more, a ECBC may also be required for the sublease. We can advise on obligations for both landlords and tenants and coordinate data collection with building management on your behalf.
