Chapters 4 to 6: the assessor fixes the sector and sub-sector, then the rated area as gross floor area to the chosen measurement standard (else GLA, GLAR or NLA), commercial car parks by all floor levels, aquatic centres with indoor and outdoor pool surface entered separately, verified by survey, lease, scaled plans, site measurement or planning documents, unverified areas going to potential error. The assessor answers the premises-type questions (24/7 operation, seasonality, whether HVAC is on the meter for part buildings) and the sector questions (for example cleanrooms in laboratories, custody cells in police stations, refrigeration in food retail), with evidence for each answer.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
