Metered Baseline Methods

This page provides information about three of the Metered Baseline Methods

About this method

The Metered Baseline Method (MBM) compares energy consumption before and after an energy savings project is implemented.  In this method, the term ‘energy’ may refer to electricity, gas, or both.

A number of diļ¬€erent methods can be used to calculate energy savings as part of the MBM:

  • Baseline per unit of output - used when consumption is strongly linked to output (eg, aluminium smelting)
  • Baseline unaffected by output - used where consumption is not linked to output (eg, hotels, schools and swimming pools)
  • Normalised baseline - used where explainable variation needs to be accounted for in the baseline (e.g weather dependent HVAC and refrigeration)
  • NABERS baseline - used for commercial buildings (see the separate NABERS page for more information) 
  • Aggregated metered baseline - uses statistical methods to calculate energy savings (see separate aggregated metered baseline page for more information)

Template Nomination Form

The Energy Savings Scheme Rule of 2009 allows an original energy saver to nominate an Accredited Certificate Provider as the energy saver in relation to the implementation of a recognised energy saving activity at a particular site. Such a nomination must be in the form and manner approved by the Scheme Administrator. Templates for nomination forms can be found on the Templates page.
