How is the rating calculated?
Shopping centres are an assembly of
variety shops, common areas, major stores and car parks, and are not homogenous. NABERS calculates a custom benchmark for each
shopping centre based on national performance data.
Energy:
The energy use of the shopping centre over 12 months is converted to
greenhouse gas emissions and divided by the area, to calculate the emissions
per m2. This figure is
compared to a predicted greenhouse gas emissions per m2 for an
average shopping centre with the same attributes and climatic conditions. The NABERS rating reflects whether the
shopping centre is performing more or less efficiently than the predicted
market average.
Water:
The water use of the shopping centre over 12 months is divided by
the area to calculate the kilolitres per m2. This figure is compared to predicted
kilolitres per m2 for an average shopping centre with the same
attributes and climatic conditions. The
rating reflects whether the shopping centre is performing more or less
efficiently than the predicted market average.
