About the tenancy lighting assessment

A tenancy lighting assessment is an important part 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 The CBD Tenancy Lighting Assessment for Offices Rules Version 3.0.

The tenancy lighting assessment measures the power density of lighting in office areas and describes the capacity of the lighting control systems. The assessment covers installed lighting and, where relevant, any proposed lighting systems. It is based on a methodical survey of the general office lighting system that can reasonably expected to be left in place after the tenant leaves and the fitout is removed.

A tenancy lighting assessment is certified for 5 years. 

The front page of the BEEC summarises the results of the assessment and compares the building with other buildings that were issued a BEEC within a specified year.

More details on the performance of each space in the building are in Part 2 of the BEEC. The 'functional spaces' are the smaller of each floor or each tenant suite. 

 

Modifying a tenancy lighting assessment

A building owner may engage an assessor to modify a tenancy lighting assessment to show any lighting upgrades that occur during the 5 year certification period. A modified tenancy lighting assessment retains its original expiry date. When a tenancy lighting assessment is modified, the building owner can engage an assessor to modify as many or as few spaces as they wish.
