Acceptable alternative strategies to sub-metering by floor plate

An alternative sub-metering strategy, not based on a by-floor-plate basis, would be acceptable provided that:

– it provides an equivalent, or more useful level of detail than sub-metering by floor plate.
– it divides the assessment in a logical manner which provides useful information to building management re: energy use.
– the approach does not conflict with requirements for sub-metering other functional areas.

The intent of sub-metering by floor plate is to allow a large homogenous function (such as office space) to be split up into smaller areas that will allow building management to monitor, identify and influence areas of high energy use. Β Alternatives that also meet this intent are also acceptable.
