The 2018 Liveable Cities Conference is being held next month over 16 – 17 July at the Pullman Melbourne on the Park.
Now in its 11th year, this Conference will continue to explore the liveability of our metropolitan and regional urban centres.
Mr Paul Bannister, Director, Innovation and Sustainability at Energy Action joins us at the conference to discuss ‘NABERS – Rating energy and water efficiency for Apartment Buildings’.
The NABERS program is well known for its work in the commercial sector, with energy and water ratings for offices, shopping centres and hotel, and energy ratings for data centres. However, although it does have a rating system for homes, it has not been focused on the residential sector.
Apartment buildings represent a significant opportunity for energy and water efficiency and in many ways actually resemble the commercial sector in terms of the presence of “base building” services that are provided to occupants that are metered separately from the balance of energy use within the individual apartments. However, the diversity of services provided varies widely both within apartment buildings of comparable size and more systematically with the scale of building. These factors create unique challenges in the creation of benchmarks for this sector.
In this paper, the characteristics of the apartment sector are reviewed based on a data set of over 250 buildings in New South Wales, Victoria, Queensland and Western Australia. Factors demonstrated to have significant impact include the number of apartments, the degree to which air-conditioning is provided centrally, the presence and servicing of the car park, the presence and servicing of a swimming pool, and the presence of lifts and gyms.
The application of NABERS style benchmarks for energy and water to this sector is presented, showing the structure of the ratings and the results from application to the data set. Benchmarks are then used to calculate NABERS-style ratings for energy and water. The sample distribution of ratings is shown to be a good match to expectation. The paper concludes with a review of the next stages in rating application and development.
Dr Paul Bannister is an international expert in the field of energy efficiency with over 25 years’ experience in the energy efficiency sector. He is the primary author of the NABERS Energy and water tools for office buildings, hotels, shopping centres, apartments and hospitals, and of the NABERS Energy tool for data centres. He has recently also completed a major review of Section J (Energy Efficiency) of the Australian Building Code. Paul has over 100 publications on energy related topics.
