08. Energy efficient equipment – Above Green

(2 credits available)

Aim

To recognise and encourage a reduction in the building's unregulated energy load through the use of energy efficient equipment to ensure optimum performance and energy savings in operation.

Assessment criteria

The following is required to demonstrate compliance:

Two credits

Identify the building's Equipment energy and estimate its contribution to the total annual equipment energy consumption of the building, assuming a typical or standard specification.

Identify the systems or processes that use a significant proportion of the total annual equipment energy consumption of the development and its operation.

Demonstrate a meaningful reduction in the total annual equipment energy consumption of the building. See Table 32

Table 32 contains solutions deemed to satisfy compliance for common examples of significant contributors to equipment energy consumption, for a number of different building types or functions.

Temperature set points are not less than 24°C, as measured at the inlet of the equipment in the rack.
E	IT-intensive operating areas	Uses a natural ventilation and cooling strategy as standard, with forced ventilation only to be used when the internal temperature exceeds 20°C and active cooling only when the internal temperature exceeds 22°C. There is a mechanism to achieve automatic power down of equipment when not in use, including overnight.
F	Residential areas with domestic-scale appliances (individual and communal facilities)	Domestic-scale appliances have the following ratings (or better) under a national or international energy efficient white goods scheme equivalent to the EU Energy Efficiency Labelling Scheme, where provided: Fridges, fridge-freezers: A+ rating Washing machines: A rating Washer-dryers, tumble dryers: B rating OR If appliances will be purchased during occupation by the tenant or owner, information on the appropriate energy efficient white goods scheme must be provided to all residential areas of the building. Note: Any white goods available to purchase from the developer must be compliant with criteria F1 to F3 above. If criterion F4 was chosen to demonstrate compliance, only one of the two available credits could be awarded.
G	Kitchen and catering facilities	The project has incorporated at least two thirds of the energy efficiency measures outlined in the section summaries of each of the following sections of CIBSE Guide TM502 (except as specified): Section 8 (Drainage and kitchen waste removal) Section 9 (Energy controls - specifically controls relevant to appliances) Section 11 (Appliance specification - not fabrication or utensil specifications) Section 12 (Refrigeration) Section 13 (Warewashing: dishwashers and glasswashers) Section 14 (Cooking appliance selection) Section 15 (Water temperatures, taps, faucets and water saving controls). Refrigeration for kitchen and catering facilities should be assessed here, not in Ene 05 Energy efficient cold storage.
H	Display lighting	Display lighting shall have a minimum luminaire efficacy of ≥ 60 luminaire lumens per circuit Watt. Display lighting shall also be controlled by a time switch to prevent operation after midnight except where the area is open to the public.
I	Overhead warm air heaters (e.g. air curtains)	In all cases where overhead warm air heaters are used, they are to be controlled using automatic temperature control. Where the units supply multiple areas then these shall be controlled by zone temperature sensors.
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.

CN1.3	Part 4: Interior design	Criteria 1 to 3 are applicable
General
CN2	Refrigeration equipment	The criteria in Small power, plug-in equipment apply to the following refrigeration equipment (where present): Air-cooled condensing units Cellar cooling Commercial service cabinets Curtains or blinds for refrigerated display cabinets Refrigeration compressors Refrigeration system controls Refrigerated display cabinets.
CN2.1	A meaningful reduction in equipment energy demand	BREEAM does not specify a level or percentage that defines a meaningful reduction in equipment energy demand. The project team must justify how they have determined or judged a meaningful reduction from the equipment energy demand and the assessor must be satisfied that this is an appropriate justification.
CN2.2	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 Equipment energy loads with respect to this issue.
CN2.3	Lifts, escalators and moving walks	This issue does not apply to lifts, escalators and moving walks. These systems are covered within the scope of Ene 06 Energy efficient transport systems and should be removed from the list of equipment energy loads with respect to this issue.
CN2.4	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 equipment energy loads with respect to this issue.
CN2.5	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 the following criterion is demonstrated: Reusing the old equipment would, over the course of its life, be a more energy efficient option than specifying new equipment.
CN2.6	Speculative projects	Where the project is speculative and there are no unregulated energy demands including any of the equipment listed in Table 32

Methodology

Estimating annual equipment 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 stage3.

Estimating a significant proportion of annual equipment energy consumption

This methodology is used to estimate which energy uses make up a significant proportion of the equipment 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.

Evidence

Criteria	Interim design stage	Final post-construction stage
All	One or more of the appropriate evidence types listed in 4.0 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 centre' 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).
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.
Equipment energy: Building energy consumption resulting from systems or processes within the building, other than Service energy. This may include energy consumption from systems integral to the building and its operation, e.g. lifts, escalators, refrigeration systems, ducted fume cupboards; or energy consumption from operational-related equipment, e.g. servers, printers, computers, mobile fume cupboards, cooking and other appliances.
White goods and small power equipment: Domestic appliances, for example washing machines, fridges, freezers, fridge-freezers, tumble dryers, washer-dryers, air movement fans or heaters, etc.
