What is NABERSNZ?
The NABERSNZ rating system is New Zealand’s benchmark for energy efficiency in commercial buildings, enabling property owners to measure and improve their building performance. NABERSNZ, adapted from Australia’s highly successful NABERS system, has played a pivotal role in driving sustainability and reducing energy consumption across New Zealand’s commercial property sector.
Bueno Analytics has a proven history of working with NABERS, making us the ideal partner for NABERSNZ-certified buildings. Our cutting-edge NABERS Tracker and Building Optimisation platform are tailored to help property owners not only meet NABERSNZ standards but excel in achieving top energy ratings.
NABERSNZ is licensed to the Energy Efficiency and Conservation Authority (EECA) and is administered by the New Zealand Green Building Council (NZGBC). Ratings are carried out by trained assessors.
A Brief History of NABERSNZ
NABERSNZ was launched in 2013 and is administered by the Energy Efficiency and Conservation Authority (EECA). EECA recognised the growing need for New Zealand’s commercial property sector to embrace energy-efficient practices. By adapting the NABERS framework, NABERSNZ provides a reliable method for measuring base building energy use across office spaces, setting a foundation for greater transparency and efficiency.
Commercial buildings use 21 percent of New Zealand’s electricity, costing business $800 million every year. On average, building energy performance could be improved by 20-25 percent.
Under the Government’s Carbon Neutral Programme, NABERSNZ ratings are required on buildings where over 2,000m2 is leased by Government agencies.
Since its inception, NABERSNZ has helped drive improvements in building performance through:
- Accurate benchmarking and independent ratings.
- Encouraging actionable steps for reducing energy use.
- Offering financial support, such as grants for HVAC optimisation, through the EECA.
EECA: A Win-Win for New Zealand’s Commercial Property Sector
The EECA HVAC Optimisation Grant is an initiative by New Zealand’s government, demonstrating strong leadership in supporting the NABERSNZ program and reducing carbon emissions from commercial properties. This funding is a unique opportunity for property owners to take actionable steps in HVAC system optimisation—a critical area responsible for a significant portion of a building’s energy use.
The grant offers substantial financial support, helping to remove barriers to investment in energy-saving projects:
- EECA may fund up to 40% of the cost of implementing a continuous commissioning system, with a maximum grant amount of $100,000.
- Eligibility requires the site to have energy systems consuming a minimum of $150,000 of energy per year, ensuring significant opportunities for energy and cost reductions.
This program highlights the EECA’s commitment to bridging the gap between sustainability goals and practical solutions, helping businesses get their energy optimisation projects ‘over the line’ while contributing to the fight against climate change.
How Bueno Analytics Helps Unlock These Savings
Bueno Analytics plays a pivotal role in supporting businesses to fully leverage EECA grants and achieve NABERSNZ success.
Our advanced Fault Detection and Diagnostics (FDD) and HVAC Optimisation solutions help property owners:
- Identify Inefficiencies: Using near real-time monitoring (every 5 minutes), we pinpoint faults, leaks, and inefficiencies that cause energy wastage.
- Optimise HVAC Systems: Continuous commissioning ensures systems operate at peak efficiency, delivering long-term energy savings and reducing carbon emissions.
- Achieve NABERSNZ Goals: By addressing issues proactively, we help clients improve their NABERSNZ ratings and demonstrate measurable progress in sustainability.
The Impact: Tangible Savings and Sustainability
- Significant Cost Savings: Optimising HVAC systems can result in up to 20% reductions in energy use, leading to lower annual operating costs. For sites consuming $150,000 of energy per year, this translates to savings of $30,000 or more annually.
- Carbon Emission Reduction: Improved energy efficiency directly reduces greenhouse gas emissions, helping businesses align with national and global climate targets.
The EECA grant, combined with Bueno’s proven expertise, makes investing in energy optimisation a no-brainer for property owners. This collaboration showcases how government funding, innovative technology, and industry action can align to create a more sustainable, cost-effective future for New Zealand’s commercial property sector.
How Bueno’s NABERS Tracker Drives Building Rating Success
At Bueno Analytics, we provide advanced tools that go beyond monitoring energy consumption—we empower property owners to achieve and maintain top-tier ratings in global building performance rating systems, including NABERS, GRESB, WELL, Green Star, and Energy Star.
Our NABERS Tracker is a core solution designed specifically to track, project, and optimise NABERS ratings, setting us apart in the building analytics industry.
How the NABERS Tracker Works
The NABERS Tracker enables property managers and sustainability teams to:
- Predict Monthly NABERS Ratings:
- Bueno’s platform continuously processes operational data, generating monthly NABERS projections.
- Clients can see real-time NABERS performance estimates—showing what their rating would be if an audit were conducted today.
- Early Issue Detection:
- Predictive Monitoring identifies potential performance deviations early, allowing asset managers to take immediate corrective actions.
- This proactive approach prevents performance slippage and ensures NABERS compliance over time.
- Customised Reporting & Insights:
- Clients receive monthly reports tailored to NABERS, showing detailed energy, water, and emissions metrics.
- In addition to the NABERS Tracking report there are a large list of operation, energy, optimisation reports & dashboards available.
- Reports can be customised for individual needs.
Achieving 6-Star NABERS Ratings
Bueno Analytics’ Building Rating System Reports provide more than just tracking—we help improve NABERS ratings through actionable recommendations. On average, our clients see up to a ½-star improvement in their NABERS rating within the first year. This translates to:
- Lower Operational Costs: Reduced energy consumption through optimised systems.
- Reduced Carbon Emissions: Direct contributions toward net-zero targets.
- Increased Asset Value: Improved ratings boost property desirability and investor confidence.
Beyond Tracking: The Optimisation Module
Tracking is only half the equation—Bueno’s Optimisation Module turns insights into action. By integrating predictive analytics and advanced diagnostics, the Optimisation Module works alongside the NABERS Tracker to:
Identify Performance Gaps: Pinpoint operational inefficiencies in systems like HVAC, lighting, and water management.
Generate Corrective Actions: Recommend custom performance adjustments to meet sustainability goals.
Provide Continuous Improvement: Deliver an ongoing roadmap for building performance upgrades, ensuring consistent rating improvements.
