Alternative transport measures not applicable to the project - KBCN0965
It is acknowledged that certain alternative transport measures may be considered not applicable to the project under assessment, due to building type, scope of refurbishment, etc.
Upon provision of clear justification for the exclusions, in such instances, in order to ensure a fair assessment, an alternative calculation method has been introduced.
This method is only applicable where there are less than six measures deemed to be appropriate and in all other instances the methodology outlined in the manual applies.
The Assessor will:
- Identify the number of measures applicable to the assessment;
- Determine the number of measures that have been complied with;
- Determine the percentage of measures achieved, and based on this, the proportion of credits achieved.
Please see the worked example below, where the Assessor:
The number of credits achieved is proportioned to the percentage of compliant measures against the total number of measures applicable to the project.
- Deems that five alternative transport measures are appropriate for the project;
- Demonstrates compliance with three of these measures;
- Determines the percentage of compliance, ie 60% (three out of five measures). This results in the awarding of 60% of the three credits available to this assessment, ie 1.8, which, to ensure robustness, will be rounded down to the nearest whole number, with a final one credit achieved.
Car sharing - KBCN0878
This measure will generally be unavailable to speculative projects.
To fully implement the car sharing option, the building occupants need to be known and signed up to a car sharing scheme in-line with the criteria.
Community transport schemes in rural areas - KBCN00013
In rural areas, where scheduled public services are insufficient to gain credits via the calculation of the Accessibility Index, community transport schemes, including 'on-demand services', can be used to achieve the 'dedicated bus service' option. In such cases evidence must be provided to demonstrate:
- It serves a rural area
- It is available to all potential users
- The service is established at the time of the assessment being submitted
- The service is of an appropriate scale for the community it serves
Content reworded to highlight the availability of the on-demand service to all potential users. 24/04/2017
Compliant wheelchair and buggy storage facilities - KBCN1200
In sheltered housing or care homes and supported living facilities assessments, compliant wheelchair and buggy storage facilities are those that meet the following:
- Charging points for electric buggies (at least two) provided within the
- Storage area must be secure yet easily accessible
- Lighting of the storage facility must be compliant with the external (or
internal where relevant) lighting criteria defined in BREEAM Issue Hea 01
Visual comfort. The lighting must be controlled to avoid operation during
daylight hours, where there is sufficient daylight in or around the facility.
- Where access to and from the building main entrance needs to be tightly
controlled for the safety/security of residents, and it can be demonstrated
that compliance with points 2 and 3 above impact on this (e.g. where
residents include those with mental health problems), these two items can
be excluded from the compliance requirements.
Cycle spaces – Minimum and maximum requirements - KBCN0637
These remain applicable where the 50% reduction allowed for building locations with a high level of public transport accessibility is in effect.
This means that, for instance, a large retail will still need to provide at least ten customer cycle storage spaces and could meet compliance with a maximum of fifty.
18.05.2017 Previous KBCN on large retail adapted to include any minimum requirement for cycle storage spaces.
Cycle spaces – Compliant types of storage - KBCN0257
Due to the number of different types of cycle storage facility available and the variation in site conditions, BREEAM New Construction is less prescriptive about the dimensions and type of cycle parking which can be used to demonstrate compliance. The Assessor is expected to exercise their professional judgement to determine whether the cycle parking spaces meet the aims of the Issue and the requirements listed in the compliance notes.
BREEAM is used to certify buildings, not products. Cycle parking systems cannot, therefore, be considered inherently 'BREEAM compliant'. These must be assessed in context with reference to their location and the intended user profile.
Cycle spaces – Folding bicycles and scooters - KBCN00024
The provision of cycle storage that is only suitable for folding bicycles or scooters is not compliant.
Providing reduced storage space for folding bicycles or scooters in place of compliant cycle storage may limit future travel options
14 03 2018 Wording clarified and reference to scooters included.
Cycle spaces – Prominent location - KBCN00053
The requirement to provide cycle storage facilities in a prominent location on site, within view of building users, is intended to encourage use through advertising their presence to building users. Providing these facilities inside the assessed building, such as in the basement, may be compliant so long as there is prominent signage to indicate their location to all building users.
Cycle spaces – Provision for extensions - KBCN0707
When assessing an extension to a building, partial refurbishment or a stand-alone building, which extends an existing facility to be occupied by the same building users (such as a classroom block in an existing school), a site-wide approach should be used to determine the number of new, compliant cycle spaces required.
In such instances a stand-alone approach cannot generally ensure that the new cycle spaces for the assessed extension would be dedicated and available to the occupants of the assessed extension, refurbishment or building. This can only be used where it can be demonstrated that the use of the new cycle storage can be effectively restricted to only those using the assessed extension, either by effective positioning and or management.
Cycle spaces – Provision for regular, large visitor numbers - KBCN0546
Where there are large numbers of visitors on a regular basis, provision of cycle storage for visitors should be based on the maximum number at any given time.
This is to ensure that at peak times enough cycle storage is provided.
Cycle spaces – Similar buildings assessments - KBCN0570
Where cycle storage and/or facilities are provided for individual units, a site-wide approach cannot be used to include all units. If, however, these are a shared facility, provided in a suitably-located communal area, this may be acceptable.
When assessing using the 'similar buildings' approach, each of the similar buildings has to be assessed separately and credits have to be awarded, based on the worst performing building.
14 03 2018 Clarified to account for suitable shared facilities
Cycle spaces – Small retail – multiple units - KBCN0187
In a development of multiple small retail units, to achieve credit, 10 compliant cycle storage spaces in total are required where it can be shown that these are accessible to all units. However, where such developments consist of multiple units over a large area or are separated by barriers such as roads, the assessor should ensure that the provision is both adequate and conveniently located for all units.
The 50% reduction allowed for building locations with a high level of public transport accessibility is not applicable in this case.
17/11/2016 Note related to the 50% reduction added.
14/03/2018 Note added regarding multiple units over a large area or separated by barriers.
Cycle spaces and facilities – Rounding calculations - KBCN0445
The calculation for the required cycle spaces and facilities must always be rounded up. If the calculation works out as 5.3 cycle spaces, 6 cycle spaces must be provided.
To determine the requirements for developments with multiple types of building user, calculate the requirement for each user group separately (rounding up to the determine the number of spaces) and then add the number of cycle spaces for each user group together.
04/10/2018 Wording amended to clarify the correct calculation method for developments with multiple user groups.
Cycle Storage – Electric cycle charging stations - KBCN1238
Electric charging stations can be considered as compliant, provided they also meet the criteria for cycle storage spaces.
However, where these are dedicated spaces, (ie they are not available for non-electric cycles), these should not constitute more than 10% of the provision required for compliance.
Cyclists’ facilities – Adequately sized lockers - KBCN0961
The requirement for adequately sized lockers is so that cyclists have a dedicated space to store their cycling equipment and clothes. It is not compliant for the space requirement to be met by providing two or more inadequately-sized lockers for each cyclist.
Requiring cyclists to separate their equipment into different lockers/storage spaces could create a barrier to uptake of commuting by bicycle.
Cyclists’ facilities – Combining different facilities - KBCN0683
Cyclists' facilities can be combined, provided that all relevant compliance requirements are met. For example, compliant showers can be combined with compliant lockers in one room, subject to the principle below.
For combined facilities to count as multiple facilities, they must be capable of being used independently of each other at the same time with reference to any space requirements, access, gender and privacy issues.
Cyclists’ facilities – Matching additional cycle spaces - KBCN00093
Where more than the minimum number of compliant cycle spaces required for BREEAM compliance is provided, it is not necessary to also provide more than the minimum number of showers/lockers/changing facilities.
Cyclists’ facilities – Provision of only one shower - KBCN0566
Where only one shower is provided, this needs to cater for users of both genders.
For a changing facility to count as an additional amenity, it must be capable of being used independently of any showers, otherwise it could not be considered as two facilities.
A shower which is a mixed gender facility must be capable of being used privately. As such, it requires adequate private changing space associated with it.
Amended to provide further clarification and to add the general principle.
Cyclists’ facilities – Shell only/shell & core assessments - KBCN0882
Cycle parking must be provided as part of the base-build for all assessment types.
Where compliance is sought for additional cyclists’ facilities, the developer should provide all aspects of the installation which fall within the scope of their work and facilitate the future completion of any aspects which do not.
For shell & core assessments, if additional facilities, such as showers and drying space, are not provided in core areas and internal walls are not provided to tenanted areas, these must be indicated on design drawings and all relevant services provided. This would include capped-off supplies and electrical points as necessary in order to facilitate the completion of the compliant facilities by the tenant.
The developer should do as much as they can, within the scope of their work, to facilitate the future installation of compliant facilities and should not do anything which would make future installation more onerous.
25/05/2018 - Wording amended to clarify the intent.
Cyclists’ facilities – Shower provision for male and female users - KBCN0536
Where a deviation from the guidance for a 50:50 split can be fully justified, (for example, based on actual occupancy data from a similar development of the same building type) this can be deemed as compliant by the assessor.
If such justification cannot be provided but design teams wish to provide a flexible arrangement for showers to suit the anticipated building occupancy, providing unisex showers accessible to all building users would be acceptable.
Cyclists’ facilities – Visitors - KBCN00014
Where the cycle spaces requirement is based on the number of staff plus visitors, customers or patients, the number of cyclist facilities required to demonstrate compliance is based on the number of cycle spaces for staff only.
Visitors, customers or patients would not be expected to have access to showers and lockers within a building.
Demand-based bus services in AI calculation - KBCN1338
Demand-based bus services operated by public transport providers can be included in the calculation of the Accessibility Index. The project team will need to determine an average number of stops per hour to allow input into the AI tool.
Education – Boarding schools - KBCN00089
The number of cycle spaces and facilities should be calculated based on the number of day pupils and boarders and these should be available to pupils and staff as appropriate.
For boarders, the cycle storage and cyclists' facilities requirement may depend upon a number of factors, such as the age of the pupils/students, distance of the residential accommodation from the school buildings and the school’s policy on cycling. Therefore, the assessor is required to calculate the appropriate number of cycle storage spaces and facilities for pupils and staff based on the relevant criteria.
Calculations, justification and supporting evidence should be provided in the assessment report.
14 03 2018 - Heading and wording clarified and amended to remove requirement for assessors to submit a technical query prior to certification.
Education – Different age ranges and/or non-acute SEN - KBCN0224
For a combined school campus the number of cycle storage spaces and compliant facilities will need to be calculated individually for each user-group of the building; e.g. the number of facilities for nursery schools, primary schools and secondary schools should be calculated as per the criteria defined for each of these education types and totalled.
Where this includes non-acute SEN facilities and the unusual structure of the classes prevents standard assessment, the assessor should use their judgement to determine whether to apply the pre-school criteria or base on the total number of staff and students.
While within the scoring and reporting tool the dominant education building type category will be selected, calculations need to be provided as supporting evidence, with the assessor's comments/notes used to clarify the calculation used to demonstrate compliance.
14 03 2018 - clarified and key information incorporated from KBCN0424
Education – Secondary schools - KBCN0119
Cycle parking spaces may be shared between students and staff, and are calculated based on the total number of staff and students as per the technical guidance.
Compliance for students can be based on the provision of compliant lockers only based on the following logic:
• Where secondary schools have sports facilities, compliance shall be based on the provision of compliant lockers only. The provision of showers or changing spaces is assumed to be included with the sports facilities are do not need to be assessed.
• Where secondary schools do not have sports facilities, cyclist facilities are assessed as per the technical guidance.
Secondary schools will, in almost all cases, will already have sports facilities including enough showers and adequate changing facilities to meet the BREEAM requirements by default. For most students however, the most important facility is likely to be adequate locker storage rather than showers or changing facilities.
Separate shower and changing facilities must be provided for staff. Locker facilities may be shared with students if appropriate, but staff lockers should be suitably located in relation to the other staff facilities.
The number of showers for staff should be based on the total number of staff and one shower for every 100 staff*, subject to a minimum of one shower being provided.
*This is based on 1 cycle storage space per 10 staff, and 1 shower per 10 cycle storage spaces.
10 03 2020 Further clarification of the intent
14 03 2018 Heading and wording clarified
Electric recharging stations availability - KBCN1128
This option requires the number of electric vehicle recharging stations (EVCS) to be based on a percentage of the total car parking for the building.
To meet compliance, the recharging stations must be available to all building users, customers and visitors.
Where on-site parking is limited to special user-groups, such as disabled, car share, car pool or visitors only, compliance can be met where the required percentage of EVCS is provided for those users, with a minimum of one EVCS, per user-group provided for on site.
02 06 2020 updated to clarify how this applies where the only on-site car parking is for special user groups.
Electric vehicle charging spaces (EVCS) – Priority spaces - KBCN1429
The current criteria for EVCS do not address provision for priority spaces, such as those allocated to disabled use and car sharing.
The assessor and design team should, therefore, take a pragmatic approach to this and, where the overall number of required EVCS permits, an appropriate proportion of these should be provided for priority spaces. This will not be deemed as 'double-counting' as the number of EVCS required should be considered independently of other requirements.
The intent is that electric vehicle charging spaces are available to all building users (where possible).
Electric vehicle charging stations - KBCN0684
As per the 'Alternative transport measures' criteria, the percentage requirement for electric charging stations should be based on the total car parking capacity for the building.
Where the assessment covers only part of a building or development this must be based on the total car parking capacity unless the parking for the assessed development is clearly segregated and available only for the use of its building users.
23 03 17 Reference to car sharing spaces removed. See also KBCN0282
Electric vehicle charging stations – shell & core assessments - KBCN1247
For shell & core and partially-fitted residential developments, compliance can be demonstrated by installing all the necessary infrastructure, (i.e. capacity in the connection to the local electricity distribution network and distribution board, as well as sub-surface ductwork to receive cabling to parking spaces), to enable the simple installation and activation of charging points at a future date.
15/11/2019 Incorrect reference to pre-installation of 'cabling' removed.
Future transport nodes - KBCN0966
Where a transport node is currently inactive but will become active soon after project completion, it can be included when calculating the existing AI.
To demonstrate this, confirmation of the start of service date and service frequency from the appropriate public transport authority or company will be required.
Hotels and other short stay accommodation – cycle storage unit of measure - KBCN0676
The unit of measure for the calculation of compliant cycle storage spaces is 10 staff and 10 visitors or beds.
The technical manual currently mistakenly refers to 1 staff and 1 visitors or beds.
N.B. It is permissible to calculate the cycle spaces based on the number of bedrooms rather than the number of beds.
23/07/2018 Wording added to include clarification on what to base the calculation of cycle spaces on.
Technical manual to be updated accordingly in next re-issue.
No data for AI at Design Stage - KBCN0551
If there is insufficient data for a future transport service to include this in the calculation of the AI at the Design Stage, it should not be accounted for.
If at Post Construction stage the data is available, this can be incorporated.
Whilst certain Design Stage requirements can be based on commitments to achieve a certain performance, this must be based on verifiable data.
16/04/18 Wording amended to clarify that this applies to future services and to allow applicability to UK NC 2018
Number of credits available - KBCN0749
In Issues 1.0 - 1.3, there is a publication error within the assessment criteria, which states the following:
“Note: up to a maximum of five credits are available from a combination of the following Accessibility Index and alternative transport measures criteria.”
The above is incorrect.
There are up to a total of 8 credits available for Tra01 (building type dependent) in this scheme:
Accessibility Index’ - up to 5 credits
‘Alternative transport measures’ - up to 3 credits
This will be corrected in the next manual re-issue
Occupancy calculation – Buildings with shift patterns - KBCN0431
In buildings with shift patterns, as shifts may overlap, the building users calculation should be based on the maximum occupancy of the building at any given time.
On-demand public bus services - KBCN1404
These can be recognised as follows:
This is limited to genuine on-demand bus services, which are operated as public transport with multiple pick-up and drop-off points and does not extend to private hire, taxi or other similar operations.
- The location of the transport node should be determined as the nearest available pick-up point to the assessed building
- The frequency of the service should be considered as the published maximum wait time (or actual average wait time, if the service is established and this data is available)
- Such services, whilst they may serve multiple destinations, should be considered as a single route
- It must be demonstrated that information on the availability and how to access the service is made available to building users
Park and Ride Schemes - KBCN0754
'Park and ride' bus services run from one or more car parks to a city centre or other destination to allow travellers to park their car at a convenient location and complete their journey by bus. These generally stop at transport nodes en route to allow passengers to board or alight.
Provided the service meets the aim of the Issue with reference to the guidance, they can be considered for this Issue in the same way as any other bus service.
Priority spaces for car sharers calculation - KBCN0282
The calculation of priority spaces for car sharers should account only for the car parking capacity that is dedicated to the staff working in the building, without considering the spaces for customers or visitors.
As such, car sharing spaces should be clearly segregated from customer/visitor parking areas.
23/03/2017 note added clarifying requirement for segregation
Safe pedestrian routes: definition, measurement and verification - KBCN0238
Safe pedestrian routes include pavements and safe crossing points or, where provided, dedicated controlled crossing points. A safe crossing point could also be a tactile crossing that drops to the level of the road, which could be used by wheelchair users. An element of assessor judgement is required and if in doubt, their justification of safe crossing points should be provided.
For measuring the distance, for example, you could measure a safe pedestrian route along a pavement, across a road at a safe point and along the pavement on the other side. The distance should not be measured diagonally across a road along the most direct route.
In terms of evidence, Google Maps may be used, provided that the scale is appropriate and clearly indicated. In order to demonstrate that the route is ‘safe’, ‘Streetview’ may be acceptable for Design Stage evidence, however this should be verified by the assessor’s site inspection and photographs of any key areas for the Post Construction Review. The assessor's site inspection is an important aspect of the assessment of this issue as it must confirm that the Google Maps and Streetview information is current, and may help to identify safe crossing points or hazards which may not be apparent from a desktop study.
The purpose of requiring ‘safe pedestrian routes’ is to ensure that there are suitable pavements and that distances are not measured using the shortest route, ignoring safety issues. If a pedestrian crossing or crossing island is available to assist crossing busy road, the route and distance should account for this.
Tram services - KBCN000004
Tram services are classified as train services when assessing transport accessibility.
Vehicle (re)charging stations/points - KBCN0934
For BREEAM purposes, a vehicle charging station is a facility that is dedicated to charging vehicles. Provision of a mains-powered electrical socket will not be deemed compliant.
