2018 changes to New Zealand Standard 4243: Energy Efficiency - Large Buildings Part 2: Lighting will effect those responsible for lighting in new builds, fit-outs or major refurbishments of large buildings.


Ecopoint was proud to represent the New Zealand Property Council on the New Zealand Standards Committee review of the above standard, providing lighting technology and project-solution expertise. We worked alongside representatives ranging from IESANZ, EMANZ, Core Logic, MBIE, EECA, BRANZ, Massey University and the Council of New Zealand Universities.

As a result of the review, Standards New Zealand announced in early 2018 that the recommended changes would be adopted and NZS 4243 has now been updated.



The review focused on improving the base level of lighting energy efficiency in large buildings. The Standard has been updated to require that the efficiency benefits from new solid-state lighting technologies are included in new buildings.

  • The Standard details new Lighting Power Density Limits (LPDLs). For all our customers dealing with large, commercial buildings, this means that consent could be declined if the new limits are exceeded.
  • The definitions of the types of building spaces that the LPDLs apply to have been increased from 13 to 31 different spaces, making it easier to quickly find the benchmark/limit for the specific space you are lighting.
  • Decorative lighting that doesn't contribute to the general lighting in the area is exempt from the LPDL.
