Full or Partial sub-metering - KBCN1203

Fully sub-metered

For an asset to be considered as fully sub-metered both heating and cooling consumption must be sub-metered for each tenant.

Partially sub-metered

For an asset to be partially sub-metered, the asset must have at least one tenant that has both heating and cooling consumption sub-metered. An area cannot be considered either fully or partially sub-metered where only one of heating or cooling is sub-metered.

Heating and cooling provided through one system - KBCN1204

Where heating and cooling is provided through the same system and it is not possible to separate the consumption related to each, then one sub-meter covering the system can be considered to be fully sub-metered.
