A tenancy lighting assessment is an important component of a Building Energy Efficiency Certificate (BEEC) required under the Commercial Building Disclosure (CBD) Program.
The tenancy lighting assessment measures the power density of the installed general lighting system of affected buildings. It does this by working out the Nominal Lighting Power Density (NLPD) of the relevant functional space in the building as well as the capacity of installed lighting control systems. It may also include a performance comment if appropriate. The assessment covers installed lighting and, where relevant, also proposed lighting systems. It is based on a methodical survey of the general lighting system reasonably expected to be left in place after the tenant leaves and the tenancy fitout is removed.
Lighting assessments are done by CBD accredited assessors using the following important documents:
- CBD Tenancy Lighting Assessment for Offices Rules Version 2 —This sets out the legislated methods and standards that CBD accredited assessors must use to do a valid lighting assessment for a BEEC. For a CBD Tenancy Lighting Assessment to be valid under the Buildings Energy Efficiency Disclosure Act 2010 (BEED Act), it must be done in accordance with these Rules.
- CBD Tenancy Lighting Assessment training slides and worked examples (applies to 'Version 1' of the TLA Rules only)—These are slides and worked examples for prospective CBD assessors to bring to lighting assessment training sessions. CBD assessors who have completed their training may use these resources to assist with onsite assessments or as a refresher when required.
