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.
Bristol Transport Access Level (BrisTAL) - KBCN1426
The Bristol Transport Access Level (BrisTAL) method provides a way of measuring the level of public transport connectivity within the city of Bristol. It is derived from the Public Transport Accessibility Level (PTAL) approach used by Transport for London. As such, the ‘Access Index (AI)’ output from BrisTAL can be used as evidence of compliance against the BREEAM and HQM Accessibility Index requirements. Please note that project teams must ensure that they use the latest version of BrisTAL, which is available here: https://maps.bristol.gov.uk/pinpoint/
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
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.
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.
Greater Manchester Accessibility Level (GMAL) - KBCN1394
The Greater Manchester Accessibility Levels (GMAL) method has been created to provide a way of measuring the density of public transport provision at any location within the Greater Manchester region. It is derived from the Public Transport Accessibility Level (PTAL) approach used by Transport for London. As such, the Greater Manchester Accessibility Index (GMAI) scores generated by the GMAL method can be used as evidence of compliance against the BREEAM and HQM Accessibility Index requirements. Please note that project teams must ensure that they use the latest version of the GMAL dataset, which is available from the data.gov.uk website (https://data.gov.uk/dataset/d9dfbf0a-3cd7-4b12-a39f-0ec717423ee4/gm-accessibility-levels-gmal
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
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
PTAL report supporting evidence - KBCN0230
For developments in Greater London where a Public Transport Accessibility Level (PTAL) report is provided, this report does not need to be supplemented by additional evidence to demonstrate compliance with criteria. The assessor should be satisfied that the PTAL report is current and accurately relates to the assessed site.
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.
Total credits available - KBCN00095
The number of credits available is determined by building type, as detailed in the table. Where the maximum score for the Accessibility Index (AI) is not achieved, additional credits can be awarded up to that maximum for the Alternative transport measures listed in the following table.
This approach is intended to recognise the relative importance of sustainable transport solutions to different building types.
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.
