Information correct as of 23rdJuly 2024. Please see kb.breeam.com for the latest compliance information.

Counterbalancing ratio fixed - KBCN0327

The requirement to analyse the counterbalancing ratio can be omitted if the project team can provide a statement confirming that it has been set by the manufacturer due to existing standards and to maximise efficiency. The remaining criteria must be met.

Escalators or moving walks – variable speed drive - KBCN1621

The requirements refer to 'a load sensing device that synchronises motor output to passenger demand through a variable speed drive'. The intent is that the inverter must operate full-time to moderate output based on passenger demand.

Evacuation lifts - KBCN0437

Evacuation lifts, which will be used during an emergency only, can be excluded from the relevant BREEAM criteria. However, if these lifts are used during the normal operation of the building, then they still need to be assessed.

Extending a lift shaft - KBCN0802

Where the scope of works regarding a lift only includes extending the lift shaft to other floors, then assessment of this lift is not appropriate.  Where changes are made to the lift system, then assessment is required. Where changes to lift systems are made, these lifts need to be included in the assessment to encourage specification of energy efficient transport systems.

Lifts with speeds 0.15m/s or less - KBCN1146

Lifts with speeds 0.15m/s or less fall outside the scope of ISO 25745 and can, therefore, be excluded from the assessment of this Issue. This applies, for example, to lifts in single dwellings or those installed in other low-rise buildings, specifically for the use of persons with impaired mobility.

New build extension using existing lifts - KBCN0444

Where the assessment is only of a new build extension (and not the existing building), lifts present in the existing building fall outside the scope of Ene 06 and do not need to be assessed. The applies only when the lifts are not being renewed or undergoing a major refurbishment.

Only lifts in building are for persons with impaired mobility - KBCN1330

Where the only lifts, escalators or moving walkways in the assessed development are for persons with imparied mobility with speeds no greater than 0.15m/s, and there are no lifts which fall within the scope of the criteria, the Issue should be filtered out of the assessment. Credits cannot be awarded by default.

Regenerative drives – requirement for specification - KBCN1253

Requirements for the specification of a regenerative drive for lift installations are subject to an analysis of resultant energy savings. However, where it can be demonstrated that this is not financially viable, accounting for payback over the service life of the installation, this option can be discounted. Please also refer to other scheme-specific guidance relating to this requirement.

Scope of the criteria for lifts – Small service lifts (dumbwaiters) - KBCN1589

Small service lifts, of the type typically used to transport prepared food and crockery in restaurants (sometimes referred to as 'dumbwaiters'), fall outside the scope of this assessment issue.

Simplified transport analysis - KBCN0562

Where a single lift is provided in a low rise building for the purpose of providing disabled access only; or where a goods lift is selected based on the size of the goods it is intended to carry, a simplified transport analysis can be provided in the form of a written statement from the appropriate member of the design team.

Transportation analysis carried out by the lift manufacturer - KBCN0232

BREEAM recognises that lift manufacturers / suppliers are often engaged to provide such specialist advice. Where the assessor is satisfied that the analysis has been carried out correctly, the analysis can be submitted as compliant evidence.
