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.
17-Jan-2024 - Scheme applicability updated.
03-Nov-2020 - Issue 2.0 of UK RFO technical manual updated with new CN detailing the above.
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.
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.
07/12/2021 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 – PIR detection systems - KBCN0335
The aim of the Health & Wellbeing category is to recognise ways to benefit occupants through giving them control of their lighting environment. Without manual overrides, presence or absence detection lighting controls (such as PIR detection systems) are not compliant with the criteria.
BREEAM recognises the energy efficiency benefits of detection systems in buildings through the Energy category. In some cases, the design team may have to prioritise one particular lighting strategy to the detriment of achieving a credit elsewhere.
17 09 2024 Updated to apply to BIU Part 1 - Lighting Controls
28 04 2021 Wording amended to include absence detection systems.
18 09 2017 Wording amended to clarify the meaning.
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.
