CETEC conducted NABERS Indoor Environment rating on this building

NABERS Ratings

NABERS is a performance-based rating system for existing buildings and tenancies.  NABERS provides four environmental rating tools

  • NABERS Energy
  • NABERS Water
  • NABERS Waste
  • NABERS Indoor Environment

NABERS rates a building on the basis of its measured operational impacts on the environment, and provides a simple indication of how well you are managing these environmental impacts compared with your peers and neighbours.

Effective and relevant measurement is very important when dealing with the health of your staff and other occupants of your building/s. It becomes critical to have true data when facing sustainability issues such as limited physical and labour resources, regulations, public credibility and productivity assessment. CETEC can offer NABERS ratings for the above in any one of the following options:

  • Indicative NABERS ratings
  • Compliant NABERS ratings
  • Supportive NABERS/ IEQ field and laboratory measurements
  • Wellbeing and productivity studies


CETEC strongly endorses the NABERS rating system since it is a stepping stone for you to improve your benchmarking, maintenance, wellbeing and productivity management.
