What’s new in this version?

• A new chapter on generated energy and captured water, which replaces the On-site Renewable Electricity Generation (OREG) Ruling.
• The rules for the Renewable Energy Indicator (REI).
• A definition of the difference between Utility Metering systems and Non-utility Metering systems.
• Treatment of metering consumption data from both types of systems.
• Validation of non-utility Metering systems.
• Small end use estimation.
• Treatment of batch supplied energy and water sources.

Application of the Rules

The Metering and Consumption Rules should be read in conjunction with the sector-specific Energy and Water Rules listed below: 

• Apartment Buildings Rules
• Hotels Rules
• Office Buildings Rules
• Residential Aged Care & Retirement Living Rules
• Shopping Centre Rules

As NABERS develop Energy and Water Rules for new sectors, these updates will be referenced in future versions of the Metering and Consumption Rules.
