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.
