The challenges of achieving a high NABERS IE rating
Obtaining a NABERS IE rating requires data from three parameters; thermal comfort, air quality and acoustic comfort. Thermal comfort data requires 12 months of continuous data from temperature sensors. It also requires a minimum of 90% annual sample data for each sensor. The problem arises when this data export is incomplete, possibly due to a faulty sensor, resulting in the final building score being penalised after-the-fact.
Lack of visibility
Temperature sensors in the majority of commercial buildings are only periodically checked as part of routine maintenance schedules. This means building owners and operators have very little visibility into whether sensors are working correctly. This is particularly important for NABERS IE as each nominated sensor needs to provide valid data for a minimum of 90% of the annual working days.
Manual data extraction
Exporting temperature sensor data in commercial buildings is often performed manually, which makes it time-consuming and expensive. An external contractor is usually hired for this purpose.
No margin for error
The data is extracted once a year because the NABERS IE rating lasts for 12 months, leaving no margin for error. If any of the temperature data is found to be incomplete due to faulty sensors during the assessment, it is too late to make any corrections and the NABRES IE rating will be significantly impacted.

PEAK data helps avoid drop in NABERS IE rating
NABERS IE score
In Sydney, a prominent commercial office building was being inspected for its latest NABERS Indoor Environment (IE) score. During the assessment, a built environment assessor identified a critical issue. Three sensors on Level 7 were malfunctioning, showing stagnant data below 21°C between October and December 2022. This sensor failure risked the building's coveted NABERS IE rating, threatening to drop it from an exceptional 6 stars to a 5.5 star rating.
PEAK Platform monitoring
Fortunately, CIM's PEAK Platform had been monitoring zone temperature data at the property since November 2021. The Facilities Manager swiftly stepped in to provide the assessors with this alternative dataset from the functional sensors on Level 7, ensuring the accuracy and integrity of the NABERS assessment.
The value of data
Thanks to the availability of data and continuous monitoring enabled through the PEAK Platform, the assessors were able to use the alternative sensor data to validate the building's thermal comfort scores. This intervention directly led to the building retaining its prestigious 6-star NABERS Indoor Environment rating, a testament to our software's capabilities in safeguarding sustainability standards.
PEAK transforms compliance monitoring for NABERS IE
A leading facilities management company oversees a prestigious portfolio of commercial properties, valued well into the billions. The renowned portfolio offers close to 300,000 square meters of premium office accommodation. The properties are renowned for their superior indoor environment and sustainability standards, attracting global companies as anchor tenants.
Critical NABERS IE rating
A critical aspect of maintaining the portfolio’s premium IE standing has been the management of over 4,700 temperature sensors, essential for tenant comfort, compliance and assessment. Historically, the process of monitoring these sensors has been highly reactive, manual and riskily relying on yearly data exports to assess compliance. Such a process is known to identify malfunctioning sensors after-the-fact, rendering the requisite temperature data unavailable to NABERS IE assessors.
The deployment of CIM’s PEAK Platform has transformed this reactive maintenance approach in favour of data-driven maintenance (DDM), as continuous monitoring and advanced AI-powered analytics now guide maintenance decisions. For our client, the process supports their delivery of an exceptional tenant experience, and ensures their NABERS IE ratings remain industry-leading. This has improved their ability to attract premium anchor tenants while avoiding penalties for failing to meet minimum lease requirements as they relate to IE ratings.
