The CBD Program Tenancy Lighting Assessment (TLA) for Offices Rules are defined and administered by the Department of Industry, Science Energy and Resources (CBD Administrator). The last major TLA Rules update (version 3.0) was published in early 2016, with additional minor updates (version 3.1 and an associated TLA Ruling) published in April 2020 to provide flexibility during the COVID pandemic.

The TLA Rules version 3.0 specified that TLAs were valid for five years. The first batch of five year TLAs that were certified under TLA Rules version 3.0 will begin to expire in September 2021. It is important to ensure that when TLAs for buildings are validated for another five years, the lighting assessments reflect current practice.

Feedback from stakeholders and CBD Accredited Assessors has highlighted the need for the TLA Rules to reflect shifts in the marketplace towards highly efficient LED lighting installations and updates to minimum lighting standards specified in the National Construction Code (NCC).

The CBD Administrator is now seeking stakeholder feedback on proposals to update the method of ranking Nominal Lighting Power Density (NLPD) levels in the TLA Rules. Please review the associated TLA Rules review consultation paper which outlines the proposals in detail.
