What is a NABERS Energy Rating


NABERS (National Australian Built Environment Rating System) is a quick, dependable, and comprehensive sustainability measuring framework used in a variety of building types, including hotels, shopping centers, apartments, offices, data centers, and more.


NABERS Energy Rating


A NABERS star rating is used to analyse a buildings energy efficiency and carbon footprint. NABERS Energy ratings are the only independent tool, which based on real-world energy data, and provides a clear benchmarked star rating comparison of a buildings cost and emissions performance over a 12 month period against all other buildings of the same type.


Benchmarking accounts for changes in climate zone, whether your keeping cool sipping a cocktail on your airconditioned apartment overlooking that tropical beach or warming yourself with a cup of tea by a snow covered mountainside, a star rating accounts for these changes in how your building performs.


A NABERS Energy rating gives you an accurate picture of how you're doing and can be used as a KPI for your energy-saving goals over time.


A NABERS Energy Base Building Apartment Rating considers the entire property area which includes lighting, power and heating, ventilation and air-conditioning across:

  • Common areas

  • Stairwells

  • Lifts and lobby areas

  • Car Parks

Key Features in DeHavilland Apartments


DeHavilland Apartments at 12 The Crescent is the only 6-star NABERS Energy rated apartment building in WA. Only six other buildings have reached this highest possible 6 star rating; and, all of these are located within NSW.


The NABERS 6 star rating independently benchmarks DeHavilland as having the lowest carbon emissions of any apartment building in WA.


Energy efficient building design


The apartments are built using timber, including the majority of the structure and the floorplates. Concrete construction is responsible for around 35% of global carbon emissions. In DeHavilland Apartments, fly ash was added to the ground floor and air blown concrete sheets were used above the structural timber on each floor which has a 90% lower carbon footprint than traditional concrete.

DeHavilland Apartments are built at a lower cost (~7% savings) and six months faster than a traditional build without high-quality sustainable building practices.


Building Features Include

  • Smart lighting with sensors and LED's

  • Car Stackers in open car park

  • Smart lift solutions



Integrated Solar and Battery system


Element47 designed and delivered the renewable energy system which included 19kW of solar PV and 30kWh of modular SENEC batteries. The system was designed to save the 9 residential, 1 commercial and common area 30% and is achieving this in operation with the average residence saving $432 per annum.




This top-performance outcome was achieved with the help of a 15kW inverter/19kW solar panel system of onsite renewable energy generation supplemented by a 30kWh SENEC battery bank which in combination contributed over 60% of the common area’s total electricity consumption of 6,232kWh. The 60% renewable energy component is excludable in rated energy for the NABERS assessment.


Smart Electricity Meters


Element47 leveraged off of the Stantec building services engineers delivered design,

and implemented the embedded network smart metering using some of the existing SATEC meters.

The SATEC electricity meters were installed the building site main switchboard and are connected to Power Ledger via Element47's Power Ledger Ready turn key solution. The excess solar energy is stored in the SENEC three phase cluster of batteries and the smart meters enable the trading of the grid and renewable electricity equitably through our Power Ledger platform.


Peer-to-Peer (P2P) Trading


Element47 chose to partner with Power Ledger to bring innovation to DeHavilland Apartments assisting it win the 2021 Innovation and technology category at the recent WA Apartment Advocacy Awards.


Real time data is captured every 15 mins through the smart meters and traded in the Element47 Power ledger online platform. Through SENEC battery control and Power Ledger trading platforms, Element47 tracks the energy usage and analyses the buildings grid independent capability against it's projected target.


DeHavilland Apartments is the worlds first independently certified energy efficiency and sustainability rating from a P2P Blockchain trading platform.


Conclusion


Element47 is committed to provide sustainable energy solutions to reduce CO2 emissions and costs.


CO2 concentrations in the atmosphere have risen by a startling 43 percent since the start of the Industrial Revolution and we are on a trajectory according to the IPCC to hit catastrophic warming of 3 degrees. Carbon dioxide emissions from human activity total 29 billion tones per year, with the majority of this coming from the burning of fossil fuels for energy.
