1.2, 1.3, 3.2 and 3.3: every NABERS energy and water rating complies with the Metering and Consumption Rules and Rulings current on the day of lodgement (unless the National Administrator approves otherwise in writing or a Commitment Agreement fixes an earlier version). Acceptable data follows the same three-tier hierarchy as the building Rules (assessor-obtained, disinterested third party, interested party), estimates are capped at 5 % of the rating's emissions or water, alternative methods need prior approval, and data is entered into the rating input form as it appears at source, without rounding.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
