Assessing industrial spaces – exemptions - KBCN0734

The thermal comfort criteria do not apply to the operational or storage areas typically found in industrial assets or other similar asset types. The criteria is still be applied to the other parts of the asset as appropriate. Operational and storage areas often have function-related thermal requirements determined by operational or storage needs. These functional requirements override the needs of any occupants.

Control of glare from sunlight – hotel rooms - KBCN1087

The primary function attributed to hotel rooms is that of a bedroom and as such, lighting and resultant glare are not considered to be problematic for these spaces. The only exception to this is where designated additional office space is provided. In these circumstances it is the role of the assessor to determine if individual spaces should be determined as ‘relevant building areas’ in accordance with guidance provided. Glare control criteria apply to building areas where lighting and resultant glare could be problematic for users.

01 Nov 2023 Applicability to BIU V6 Commercial confirmed
This KBCN aligns with KBCN0666 from UKNC 2014

Glare control – alternative measures - KBCN0139

Alternative forms of glare control to those listed in the guidance can potentially be accepted, if it can be justified to the BREEAM assessor that the proposed system will effectively eliminate disabling glare and the assessor accepts this.

Indoor and/or outdoor space – Shopping Centers - KBCN1143

The Shopping Center requirements for this issue only apply to retail assets comprising of: 

1. A minimum of 15 stores 

or 

1. A floor area of at least 121,000ft2 

N.B. When carrying out the assessment of common areas only, the criteria apply to the whole building rather than just the common areas.

Indoor and/or outdoor space – Shopping centres - KBCN1143

The Shopping centre requirements for this issue only apply to retail assets comprising of:

1. A minimum of 20 stores
2. A floor area of at least 37,000m²

N.B. When carrying out the assessment of common areas only, the criteria apply to the whole building rather than just the common areas.

Intakes and exhausts closer than stated in criteria - KBCN0120

If the location of the building’s air intakes and exhausts are closer than given in the manual, compliance can be achieved where they are designed in accordance with BS EN 13779:20071 Annex A2.  If the location of the building’s air intakes and exhausts are closer than given in the Technical Manual, it may be feasible to demonstrate compliance with the BREEAM criteria using alternative methods [eg wind tunnel studies, computational fluid dynamics (CFD) modelling]. If the alternative method demonstrates that the proposed location of intakes and extracts prevents recirculation of exhaust air under typical wind conditions, then the credit may be awarded, providing all other compliance requirements are met. If this cannot be achieved and the distance requirement is not met, then the credit must be withheld.

Intakes and exhausts closer than stated in criteria - KBCN0120

If the location of the building’s air intakes and exhausts are closer than given in the manual, compliance can be achieved where they are designed in accordance with BS EN 13779:20071 Annex A2. If the required distance between intakes and extracts is not achieved through design, it may be feasible to demonstrate compliance with the BREEAM criteria using CFD modelling. If CFD modelling demonstrates that the proposed location of intakes and extracts prevents recirculation of exhaust air under typical wind conditions, then the credit may be awarded, providing all other compliance requirements are met. If this cannot be achieved and the distance requirement is not met, then the credit must be withheld.

Internal lighting levels where computer screens are used - KBCN0283

For areas where computer screens are regularly used projects can specify 300 lux, as referenced in CIBSE Lighting Guide 7, rather than the levels prescribed in the standard EN 12464:2011.

07 Dec 2021 Applicability to BIU V6 Commercial confirmed.

Non-specific levels of performance within local legislation - KBCN1152

In areas where the local legislation does not specifically outline the exact requirements related to inclusivity of access, it is often difficult for asset owners to demonstrate how they exceed the legal requirements. Therefore these assets can demonstrate compliance by providing evidence that the asset meets all of the following: The asset has features within which ensure that persons which are less able-bodied, are able to utilise the same facilities as all other building users. These include:

• Access to the asset entrance
• Horizontal and vertical (where relevant) circulation within the asset (this should be considered for normal operation, as well as emergency evacuation situations)
• Appropriate use of building functions
• Appropriate use of building controls (specification of suitable controls, switches etc.)
• Sanitary accommodation, including toilets, showers, changing facilities etc.

Alongside this, the Assessor must provide confirmation of the exact legislation which is applicable to the asset, and provide a short statement outlining the requirements within it.

Occupant control – spaces requiring user controls - KBCN0170

This guidance is intended to clarify the types of area for which user controls are required or would be considered beneficial. Zoning is required in all areas of the asset where specified in the assessment criteria. Please refer to the specific requirements of the applicable BREEAM standard to interpret this guidance appropriately. User controls required Spaces where users are expected to have independent control over their environment.

• Owned spaces: small rooms for a few people. For instance, cellular offices, owned spaces in residential assets.
• Temporarily owned spaces: where occupants expect to operate the environmental controls while they are there. For instance, meeting rooms and hotel bedrooms.
• Shared spaces. For instance, multi-occupied areas such as open-plan offices or workshops.

User controls not required Spaces where users are not expected to have independent control over their environment.

• Managed spaces: where environmental control is expected to be centrally managed. For instance, atria, circulation areas, concourses, entrance halls, function halls, restaurants, libraries, and shops.
• Occasionally visited spaces. For instance, storerooms, bookstacks in libraries, aisles of warehouses, toilets.

14-Dec-2022 - KBCN applicability updated to include BIU. Wording clarified, and amended for compatibility with BIU criteria.

Zoning and occupant control – access to lighting controls - KBCN00032

The relevant areas for the criteria apply only to areas where users are expected to have control. For instance, this means that areas intended for the general public, or a shop floor would not be expected to have lighting controls. The general principle which applies to user access to general environmental controls (heating, cooling, ventilation) may also apply to access to lighting controls. See KBCN0170. However, the the exact approach may differ between the two types of systems and assessor judgement must be used to determine compliance. In all cases zoning is required in all areas of the asset where specified in the assessment criteria. Please refer to the specific requirements of the applicable BREEAM standard to interpret this guidance appropriately.

14-Dec-2022 - KBCN applicability updated to include BIU. Wording updated. Link to KBCN0170 created.

Zoning and occupant control – whiteboards and display screens - KBCN1433

Whiteboards and display screens in dedicated teaching or presentation spaces require separate zoning and control for lighting, as specified in the criteria. Lighting around whiteboards and display screens which are typically found in general office areas, meeting rooms, or in other generic spaces do not require separate zoning and control to meet the criteria. In such cases, the assessor should provide justification. Whiteboards and display screens in dedicated teaching / presentation spaces are likely to be used frequently, and require appropriate zoning and control. An increasing number of offices and meeting rooms now include display screens - however separate zoning and control may not be appropriate.
