ENE 16 - Monitoring tenanted areas

Centralised air handling units (AHU) - KBCN0941

The requirements of the:

• Second sub-metering credit (New Construction).
• Issue (BREEAM In-Use).

do not apply to centralised AHUs, where it is not technically feasible to sub-meter energy use by separate functional, tenanted or floor areas. The credit(s) will be assessed based on the remaining applicable energy uses.

06-Mar-2024 - Scheme applicability extended to V6.

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.

Single tenant - KBCN1640

Where the assessment area is only occupied by a single tenant, the issue is not filtered out. All relevant credits apply. The criteria is designed to recognise efforts between the asset owner and tenants to coordinate sustainability policies and resource monitoring. This principle is not affected by having a single tenant, even if they might act in the role of a managing occupier.

Sub-metering using non-intrusive load monitoring (NILM) systems - KBCN1710

Non-intrusive load monitoring (NILM) systems cannot be used to demonstrate compliance for the sub-metering credits within BREEAM. Hardware-based sub-meters must be installed. NILM systems are generally retrofit systems which can be easily removed and are not integral to the building or installed building services.
