NABERS Energy & Water Ratings

A rating you can stand behind.

Accredited NABERS Energy and Water assessments for office buildings, led directly by Jarrad and Raf and supported by practical metering and data expertise.[3]

Robust, thoroughly validated submissions.

NABERS Energy and Water for Offices ratings must be performed by a NABERS Accredited Assessor and follow the current rules for gathering, interpreting and using data.[1]

Office ratings use real operational data collected over 12 months.[2] A NABERS rating benchmarks your building’s performance, while our services can highlight where further investigation or improvement may be worthwhile.

Indicative projection

See the direction before certification.

Where sufficient data is available, Taktet can use monitored consumption trends and assessor knowledge to provide an indicative projection of rating direction and compare current consumption with prior periods.

Important: any projection is an estimate only—not a certified NABERS rating or a guarantee of the final result. NABERS states that calculator results are indicative and cannot be promoted or published as official ratings.[5]
