ENE 15 - Monitoring energy uses

Clarification – percentage of end uses - KBCN1650

This percentage is measured by the energy consumption (kWh) of significant energy uses, not by the number of end uses.

Combined system for heating / cooling and domestic hot water - KBCN0329

It is permissible to have combined metering for a shared on-site or district system that combines heating / cooling, and domestic hot water generation. In all cases, justification is provided in the QA report for the combined metering, and explains why it is not technically feasible to provide separate meters.

21-Sep-2022 Applicability of KBCN added to BIU V6. Amended to include district heating and cooling networks.

Erratum – up to V6 – methodology – no default energy assumptions - KBCN1630

The scope of the issue applies only to systems with significant energy use. The methodology section states that the online platform will calculate default values, and use this to indicate which systems are in scope. This is incorrect, as default values are not automatically calculated. The energy use of each system will need to be manually estimated. This can be done based on:

• Typical benchmark values, and / or,
• Estimates based on the capacity of equipment, and annual equivalent full load hours of use.
