Tenancy lighting assessment rules
The Tenancy Lighting Assessment (TLA) measures the power density of the general lighting system in office areas and describes the capacity of installed lighting control systems. The assessment covers both installed and proposed lighting, where applicable. It is based on a methodical survey of the general office lighting that can be reasonably expected to be left in place after the tenant leaves and the tenancy fitout is removed.
A tenancy lighting assessment is an important component of a Building Energy Efficiency Certificate (BEEC) required under the Commercial Building Disclosure (CBD) Program.
The assessment is carried out by a CBD Accredited Assessor using the CBD Tenancy Lighting Assessment for Offices Rules (the Rules).
The CBD Tenancy Lighting Assessment for Offices Rules version 4.1 are now in effect.

Modifying a tenancy lighting assessment
A tenancy lighting assessment is certified for 5 years. During this period, a building owner may engage an Accredited Assessor to modify a certified assessment to show any lighting upgrades that occur. A modified tenancy lighting assessment retains its original expiry date. When a tenancy lighting assessment is modified, the building owner can choose to modify as many or as few spaces as they wish.
If an Accredited Assessor is asked to modify an assessment that they submitted originally, the assessment will be readily available to modify through the assessor portal.
However, if a different Accredited Assessor completed the original assessment, any subsequent Accredited Assessors will need to contact the CBD operations team to confirm that they have the building owner's permission to modify the assessment. The CBD operations team will then release the assessment for modification through the assessor portal.
