Refrigeration (see CN3) for kitchen and catering facilities should be assessed here, not in Ene 05 Energy efficient cold storage.
Energy efficient white goods scheme and equivalent rating scheme (Category reference F) Energy rating certifications other than the EU labelling scheme will be accepted, providing the energy efficiency performance is equivalent to the EU labelling scheme. This can be any internationally recognised energy efficiency labelling scheme for white goods or a national scheme developed for use in the country of assessment, for example Energy Label (in the EU), Energy Star (in the USA), The Appliance Energy Rating Scheme (in Australia), etc. A statement confirming that the scheme is nationally recognised and can be regarded as equivalent to the EU labelling scheme is required for use. Large-scale equipment in Healthcare (Category reference G) This includes commercial-scale catering and laundry equipment, and all other equipment with connected electrical loads in excess of 10kW rated input power. All medical equipment can be exempted from complying with the criteria.

Compliance notes

Ref	Terms	Description
Shell and core
CN1	Applicable assessment criteria	This issue is not applicable.
Simple buildings
CN2	Applicable assessment criteria	Criteria 1 and 2; ‘Ref B Swimming pool’ from Table 28 are not applicable. All other criteria relevant to the building type and function apply.
General
CN3	Refrigeration equipment	Ref H in the Checklists and tables section apply to the following refrigeration equipment (where present): Air cooled condensing units Cellar cooling Commercial service cabinets Curtains/blinds for refrigerated display cabinets Refrigeration compressors Refrigeration system controls Refrigerated display cabinets.
CN3.1	A meaningful reduction in unregulated energy demand	BREEAM does not specify a level or percentage that defines a meaningful reduction in unregulated energy demand. The project team must justify how they have determined or judged a meaningful reduction from the unregulated energy demand and the assessor must be satisfied that this is an appropriate justification.
CN3.2	Cold storage	The criteria do apply to commercial kitchen refrigeration but not to other commercial or industrial sized refrigeration and storage systems. These systems are covered within the scope of Ene 05 Energy efficient cold storage and should be removed from the list of unregulated loads with respect to this issue.
CN3.3	Lifts, escalators and moving walks	This issue does not apply to lifts, escalators and moving walkways. These systems are covered within the scope of Ene 06 Energy efficient transportation systems and should be removed from the list of unregulated loads with respect to this issue.
CN3.4	Laboratory systems	This issue does not apply to laboratory ducted fume cupboards. These systems are covered within the scope of Ene 07 Energy efficient laboratory systems and should be removed from the list of unregulated loads with respect to this issue.
CN3.5	Reuse of equipment	Reuse of electrical equipment does not comply by default, as it may not be the most energy efficient option. However, the credit could be awarded if either of the following criteria are demonstrated: The existing electrical appliances meet the criteria for inclusion on the Enhanced Capital Allowance Scheme Energy Technology Product List6Enhanced Capital Allowance scheme, http://www.eca.gov.uk. Reusing the old equipment would, over the course of its life, be a more energy efficient option than specifying new equipment.
Building specific
CN4	Healthcare Large-scale equipment See criterion 1 and Ref G.	This includes commercial-scale catering and laundry equipment and all other equipment with connected electrical loads in excess of 10kW rated input power.

Methodology

Estimating annual unregulated energy consumption

A method should be used that estimates actual energy use, based on expected equipment loads and hours of operation. The energy uses may be estimated by using simple hand calculations, benchmark data or by the methods described in CIBSE TM54: Evaluating operational energy performance of buildings at the design stage7TM54: Evaluating operational energy performance of buildings at the design stage. CIBSE. 2013.

Estimating a significant proportion of annual unregulated energy consumption

This methodology is used to estimate which energy uses make-up a significant proportion of the unregulated energy uses and so detailed calculations are not required. The approach should focus on identifying the larger energy uses that should be included and the small energy uses that can be excluded. As a guide, energy uses making up at least 90% of the estimated total annual energy consumption should typically be included (this is a statutory requirement in Wales, Northern Ireland and England – see Ene 02 Other information).

Evidence

Criteria	Interim design stage	Final post construction stage
All	One or more of the appropriate evidence types listed in The BREEAM evidential requirements section can be used to demonstrate compliance with these criteria.

Additional information

Relevant definitions

Data centre: For the purpose of this BREEAM issue, the term ‘data centres’ includes all buildings, facilities and rooms which contain enterprise servers, server communication equipment, cooling equipment and power equipment, and may provide some form of data service (e.g. large-scale mission critical facilities all the way down to small server rooms located in office buildings).
Government’s Buying Standards: A website listing minimum and best practice standards for equipment being procured for projects.
IT-intensive areas: These include computer areas where more than one computer per 5m² is provided, e.g. training suites, design studios, libraries’ IT areas and other areas with a high density of computing devices.
Office equipment: Computer monitors, desktop computers, scanners, photocopiers, printers, workstations etc.
Regulated energy: Refer to BREEAM issue Ene 01 Reduction of energy use and carbon emissions.
Unregulated energy: Building energy consumption resulting from a system or process that is not ‘controlled’, i.e. energy consumption from systems in the building on which the Building Regulations do not impose a requirement. This may include energy consumption from operational-related equipment, e.g. computers, servers, printers, laptops, mobile fume cupboards, cooking, audio-visual equipment and other appliances etc. Unlike the definition for Ene 01 Reduction of energy use and carbon emissions, for this issue, it does not include energy consumption from systems integral to the building and its operation, e.g. commercial/industrial refrigeration systems; lifts, escalators and other transportation systems; and ducted fume cupboards; because they are already assessed separately in issues Ene 05, Ene 06 and Ene 07 respectively.
White goods and small power equipment: Domestic appliances for example washing machines, fridges, freezers, fridge-freezers, tumble dryers, washer-dryers, air movement fans/heaters, etc.
