ENE 08 - Energy Efficient Equipment

Assessing equipment to be provided later by the tenant/occupier - KBCN0609

The efficiency of equipment to be provided as part of a subsequent fit-out falls outside the scope of this Issue. Likewise, in a fully fitted but speculative office, where an unknown future tenant will be providing, for example, their own computers, these computers are to be excluded from the assessment. Compliance must be demonstrated by the equipment fitted/installed within the scope of the development being assessed and, unless specifically stated otherwise, the use of commitments or legally-binding agreements is not accepted to demonstrate compliance for final certification within this BREEAM Scheme.

24/02/2017 CN amended to incorporate KBCN0701

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.

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.

---

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.

Display lighting - KBCN00097

The display lighting listed in the table includes internal lighting only. External lighting is covered in issue Ene 03.

Kitchen and catering facilities – CIBSE TM50 (2021) - KBCN1474

The BREEAM guidance refers to TM50: Energy efficiency in commercial kitchens. The BREEAM guidance refers to TM50: Energy efficiency in commercial kitchens. The 2009 version has now been superseded by TM50 (2021). The updated version may be used to demonstrate compliance, however a number of the relevant section numbers have changed. These relate to the current BREEAM guidance, which is based on TM50 (2009) as follows:

	TM50 (2009)	TM50 (2021)
1	Section 8 – Drainage and kitchen waste removal	Section 9
2	Section 9 – Energy controls – specifically controls relevant to appliances	Section 8
3	Section 11 - Appliance specification – excluding fabrication or utensil specifications	Section 13
4	Section 12 – Refrigeration	Section 14
5	Section 13 – Ware-washing: dishwashers and glasswashers	Section 15
6	Section 14 – Cooking appliance selection	Section 16
7	Section 15 – Water temperatures, taps, faucets and water-saving controls	Section 10

17 Nov 2021 - Re-formatted and applicability to BREEAM International schemes confirmed

New EU energy labels - KBCN1445

Background

In recent years, the market for domestic-scale appliances has seen excellent progress, with increasingly energy-efficient products becoming widely available. Consequently, the A-rated category was extended over time to include A+, A++, and A+++ ratings. Meanwhile, the lower ratings, such as E, F and G have become increasingly rare. It was clear that an adjustment to a new, simpler set of ratings was required.

Statutory Changes

From 1^st March 2021, the European Commission requires new, updated energy labels of A to G for dishwashers, washing machines, fridges and electronic displays. Lamps will require the new ratings from 1^st September 2021 and requirements for re-labelling tumble dryers are yet to be confirmed. This means:

• A+ to A+++ will transition mainly to C through to F
• A and B will initially apply to very few products
• G ratings will be phased out, with F ratings to follow

Changes for BREEAM and HQM

As a result of the introduction of the new EU ratings and in order to maintain the original intent of the BREEAM criteria, the approach for our schemes has had to change. It is not possible to establish direct equivalence between the old and new energy labels, therefore the updated approach will be to recognise the best-performing 25% of each appliance type, based on a comprehensive market sample. The table below shows how this translates into the new EU Energy Labels for different appliance types.

Appliance type	Rating required
Fridges, fridge-freezers, freezers	E
Washing machines	B
Dishwashers	D
Washer-dryers	D - D

  This approach will ensure that BREEAM continues to drive the energy efficiency of appliances by demonstrating a meaningful reduction in energy consumption. Note that these new requirements will be reviewed from time to time and may be subject to change. Where assessments have already specified (and can procure) products bearing the old labels, it is acceptable to follow the previous criteria. However, where products bear the new label and for all assessments registered after 31/05/2021, the new criteria must be met.  

17 Apr 2023 - Applicability to NC2013 confirmed.
21 Mar 2022 - Confirmation added that washer-dryers require a D rating for both cycles
23 Nov 2021 - Reference to 'freezers' added to appliance types
12 May 2021 - Guidance updated and applicability to HQM One and BREEAM NOR confirmed

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.
