Tra 03a - Alternative modes of transport

Car sharing – aim and principles - KBCN1510

Aim The aim of this measure is that the asset’s management establishes, promotes and administers a process which encourages building users to share private car journeys to and from work, reducing the number of cars used for this purpose. Principles A car sharing group will, generally:

Be available to all building users who normally travel to work by private car.

A car sharing group is not:

A vehicle hire/loan scheme.
Intended to offset journeys which would otherwise have been made by public transport or active travel modes (e.g. walking or cycling).

The criteria do not prescribe what terms and conditions should be implemented and, whilst the above principles should generally be followed, specific arrangements may vary. Evidence and justification must always be provided to demonstrate that the above aim is met.

Car sharing – calculation of priority spaces - 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 spaces for customers or visitors. Car sharing spaces should be clearly segregated from customer / visitor parking areas.

21-Jul-2026 - Scheme applicability updated.
06-Sep-2023 - Title updated to align with naming protocol.
23-Mar-2017 - Note added clarifying requirement for segregation.

Car sharing – location of priority parking - KBCN0796

Priority spaces for car sharers need to be located in the nearest available parking area to the main building entrance or to an entrance regularly used by the car sharers. For refurbishment projects, this applies regardless of whether external works or changes to car parking areas are within the scope of works. Assigning and clearly marking out the location of priority parking spaces is a measure that can be taken by any project regardless of scope, provided there are suitable external parking areas.

21-Jul-2026 - Scheme applicability updated. Wording expanded to clarify how KBCN applies to refurbishment projects. Title updated for consistency.
22-Sep-2022 - Applied to UK NC 2018.

Car sharing – speculative projects - 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.

21-Jul-2026 - Scheme applicability updated. Title updated for clarity.

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. Where internal walls are within scope, a compliant changing area must be provided, however for lockers, compliance can be achieved by providing a design drawing showing that there is an adequately sized and suitably located space for the required number of compliant lockers. 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.

01 Oct 2024 - Addition paragraph added to clarify the approach for changing areas and lockers.
25 May 2018 - Wording amended to clarify the intent.

Electric Vehicle (EV) Charging – Shared Parking for New Buildings, Extensions, and Phased Developments - KBCN1827

The required number of EV charging points must be based on the total number of parking spaces that serve the assessed building. This total includes both existing spaces and any new spaces associated with the project. Where parking is shared across a wider site, the “associated” number of spaces refers to the amount of parking the assessed building is expected to rely on for its occupants. A proportional allocation calculation must be used to determine this number. Example: If a project sits on a site with 1,000 shared spaces but the new building’s occupancy requires only 100 spaces, the EV requirement is calculated based on 100 spaces, not the full 1,000.

General Requirements
- Defining the parking that counts. Use a proportional allocation method to determine how many spaces in a shared car park are associated with the project.
- Short-stay exclusion: Short-stay spaces with a maximum stay of 15 minutes (e.g., pick-up/drop-off bays) are excluded from the EV calculation.
- EV Charging points location: EV charging points should be installed as close as possible to the building’s main entrance to ensure convenient access for the building users.
- Existing infrastructure: Existing EV charging points in a shared car park can only be counted when:
  - They exceed the BREEAM requirement for the buildings they were originally installed to serve,
  - They meet current BREEAM requirements, and
  - They form part of the new project’s allocated parking.
- No “legacy” exclusions: Existing parking spaces cannot be excluded simply because they predate the BREEAM assessment. If the spaces serve the assessed building, they are in scope.
- Operational policy. It is recommended, but not mandatory, that building management implement operational measures (e.g., signage, permits, digital access controls) to help ensure that EV spaces are used by the intended building users.
New Buildings on a Site or Extensions
- Calculation basis for new buildings or extensions, EV requirements must be based on the total parking demand associated with the project, including both existing associated spaces and any new spaces created.
- Proportional allocation formula
  - Determine the project’s share of the total site parking using either GIA or occupancy.
  - Allocated project parking = Total site parking × (Project GIA ÷ Total GIA), OR
  - Allocated project parking = Total site parking × (Project occupancy ÷ Total occupancy)
Phased Development
- Current Phase: The EV calculation should be based on the parking demand of the phase under assessment, including the existing infrastructure and any new parking spaces delivered in that phase.
- Existing Infrastructure: EV charging provision installed in previous phases may count towards compliance where it meets the required threshold for the current phase
- Future Phases: Provisions in future phases may be counted only if secured by a legally binding commitment (such as a signed contract or planning obligation) with a confirmed delivery timeline.

Electric vehicle charging stations – Requirement to demonstrate that electric vehicles have lower CO2 emissions - KBCN1622

This requirement is now considered obsolete and it is no longer a requirement where compliant electric vehicle charging points are installed.

Electric vehicle charging stations – Short-term visitor spaces - KBCN1735

Where it can be demonstrated that parking spaces for visitors will only be used for short-term parking (a maximum of 15 minutes), these spaces can be excluded from the calculation for EV spaces. This exclusion will typically apply to certain types of retail outlet, where visitors are, for example, collecting or dropping off orders. However, other situations can be considered, where justified.
