Communal Laundry Facilities – Domestic or Commercial Washing Machines - KBCN0613

The table provided in the manual highlights the criteria for an appliance to be considered domestic or commercial. However, for multi-residential projects (or other building types containing laundry facilities), the BREEAM assessor should use their judgement to determine whether the appliance is commercial or domestic, and justification of the category selected must be provided. For instance, commercial and domestic sized washing machines can be defined based on load size or power rating.

Communal Laundry Facilities- Commercial Sized Tumble Dryers - KBCN0555

Tumble dryers should be taken in to account when calculating the total annual unregulated energy consumption of communal laundry facilities with commercial sized appliances.  Heat recovery from a commercial sized tumble dryer exhaust can be used as an alternative to the solutions listed within the Ene 08 credit issue provided it will achieve a meaningful reduction of energy demand, and justification can be given as to why  this method has been implemented over those recommended in the manual.  The list of equipment types and compliance requirements is not intended to be exhaustive, however where alternative solutions are proposed, the design team must provide justification and evidence as outlined above, to the satisfaction of the assessor.

Deemed to comply solutions – alternative proposals - KBCN1214

The solutions listed for each category in the Table are examples deemed to comply with the requirements, without further justification or calculations to demonstrate a meaningful reduction in unregulated energy consumption. If an alternative solution is proposed, justification and/or calculations are required to demonstrate this.

Measures in CIBSE TM50 for Kitchen and catering facilities - KBCN0663

The measures are listed in the section summaries (blue boxes) in the guide. The sections that follow each summary in the Guide are explanations of the measures. Therefore you can refer to these parts if you need further clarification about the measures. When considering which measures to target, first discount any energy efficiency measures which are not applicable to the project, or are specifically excluded in the criteria. Of the remaining measures, where the criteria requires that two thirds or more are to be achieved always round up any figures. For instance if there are five applicable measures in a section, four will need to be achieved. If there are only two, both will need to be achieved. Many measures in TM50 require consideration of what is the best option or specification. The intent of our criteria is to demonstrate that these measures have been considered by the relevant specialist and have informed the design and specification of the catering facilities, but energy savings do not need to be quantified. At design stage it is acceptable for a letter or document to be produced confirming how each measure has been considered along with justification for how this has informed the specification. Where the measures require training to be carried out, relevant training materials could be used as evidence. At post-construction stage, any type of general evidence deemed appropriate by the assessor would be sufficient to confirm the specified measures have been installed.

No unregulated energy consumption in the building - KBCN00066

Where there are no items, contributing to the unregulated (or equipment) energy consumption in the building, there is currently no mechanism to award credits. If, however, in this situation, significant contributors, not listed in the table, will be specified, the design team should justify how a meaningful reduction will be achieved for these contributors, in order to demonstrate compliance.
08/05/19 Wording amended to account for situations, where a meaningful reduction in unregulated energy can be demonstrated by other means.
18.05.2017 KBCN applicability removed for NC2011 and NC2013, for which compliance can be demonstrated via the three shell and core options, as per the technical manual.

Office equipment – mobile devices - KBCN00041

Mobile devices such as smartphones and tablets, which are generally used without connection to an electrical power source, should be excluded from the assessment of the energy efficient equipment issue. Devices which are not generally connected to an electrical power source when used are excluded from the 'office equipment' definition as they do not directly affect the unregulated energy consumption of the building.    

Re-used electrical equipment - KBCN0325

BREEAM does not currently recognise the reuse of electrical equipment as the most energy efficient option for compliance with this issue. If it can be demonstrated that such existing electrical appliances meet the criteria for inclusion in the relevant national or international energy efficient equipment schemes, these can be considered compliant. If new equipment is procured in addition to the re-use of the old equipment, the existing equipment may be excluded from this assessment. In these situations the assessor must be satisfied that the new equipment would make a meaningful reduction to overall unregulated energy consumption. This issue assesses the reduction of unregulated energy consumption in operation and does not currently assess embodied energy in the manufacture of equipment.
