Capability Statement

The Building Energy Efficiency Certificate (BEEC) consists of two parts which enables an assessment to be carried out. The first part of a BEEC assessment contains a National Australian Built Environment Rating System (NABERS) Energy rating and the second part consists of a Tenancy Lighting Assessment (TLA). 



What is a BEEC?

A Building Energy Efficiency Certificate (BEEC) details the power efficiency rating of a building through the use of two assessment tools, which are:
  • NABERS Energy star ratings
  • A CBD Tenancy Lighting Assessment (TLA)
Once approved, BEECs are made publicly accessible through the Building Energy Efficiency Register. Building owners can also use BEEC in promoting the energy efficiency of their building to prospective buyers and tenants.
A BEEC is required for the sale, lease and sublease of all commercial buildings over 1,000 square metres. The NABERS Energy star rating from the BEEC is also required in any advertising used for the sale, lease and sublease of a building.

Expiration period of a BEEC

A BEEC is valid for up to 365 days and consists of a:

  • Certified NABERS Energy for offices rating which is valid for up to 365 days
  • Certified TLA which is valid for five years

As such, although the TLA is valid for five years, the BEEC and NABERS Energy for offices rating will need to be renewed on an annual basis. 


How is a BEEC Assessed?


BEEC is assessed through a series of steps as outlined below:

  1. Check if the building has an existing BEEC by searching the building’s name and/or location on the Building Energy Efficiency Register.
  2. Contact a CBD accredited assessor to discuss a fee.
  3. Gather relevant information such as lease documents and electricity bills that occurred within the last 12 months.
  4. Wait for the CBD assessor to perform the NABERS Energy rating assessment and the Tenancy Lighting Assessment.
  5. The CBD assessor will submit the BEEC application. The details of the application include the name of the assessor, the accreditation number, the building owner’s details, as well as valid NABERS and TLA certification.
  6. Once the BEEC application is approved by the Australian Government Department of the Environment and Energy, a copy of the BEEC will be sent to the CBD assessor, as well as the certificate being added to the Building Energy Efficiency Register.

So what is a NABERS Energy rating and what is a TLA?


NABERS Energy star ratings:

A NABERS Energy rating assessment is the first part of a BEEC and is one of the two mandatory components required in receiving one. To supply a NABERS Energy star rating, our assessors compare your building's performance to benchmarks set by actual building performance data. NABERS Energy star ratings through BEEC include a star rating as well as an additional rating based on the building’s annual levels of energy consumption and greenhouse gas emissions.The NABERS rating for offices are a base building rating which includes areas that are managed by the building owner such as the building’s central services. If a base building rating cannot be determined because the utility measure cannot differentiate between base building energy and tenancy energy use, an overall building rating may be used instead.


Tenancy Lighting Assessment (TLA):
The second part of a BEEC assessment includes a TLA. By working out the power density of the electrical infrastructure within the building, our assessors are able to measure the Nominal Lighting Power Density of a building's lighting system once a tenant leaves and then provide performance comments if appropriate.
A TLA consists of two main components:
  • An assessment of the Nominal Lighting Power Density (NLPD). This measures the power density of the installed general lighting system and is calculated for each tenancy space (expressed in W/m^2). The result garnered here is then graded from "Excellent" to "Very Poor". The lower the NLPD, the better the grade will be.
  • An assessment of the Lighting Control System (where applicable). Each system will be assessed for each functional space and will be graded from "Good" to "Poor".
Why are both necessary?

In conjunction with one another, the NABERS Energy star rating and TLA are both tools which ultimately serve to ensure that the energy efficiency of a building is accurately measured and made known to potential buyers in the event that the building is offered for sale, lease or sublease.


Cost and Timing Commitments

Ultimately, the cost and time associated with obtaining a BEEC is dependent on the complexity and scale of the project itself, and will be discussed between the building owner/lessor and the CBD accredited assessor. In saying this, costs can vary greatly and range anywhere between $2000 and $13,000.
