Tra 04 – Maximum Car Parking Capacity

Information correct as of 14thNovember 2024. Please see kb.breeam.com for the latest compliance information.

No car parking provision - KBCN00059

Where the assessment criteria are applicable to a building that has no car parking spaces and where there are no parking spaces accessible to building users, the benchmarks can be considered to be met. If, however, parking is shared with other buildings or parking spaces are available on a campus-type site then the provision must still be assessed.          

Obligation to provide a minimum number of car parking spaces exceeding BREEAM requirements - KBCN0401

Where it can be demonstrated (by documentary evidence) an obligation to meet a ’minimum car parking requirement’ which exceeds the BREEAM benchmarks is imposed by the planning authority, as long as no more than the stipulated minimum spaces are provided, a single credit can be awarded.

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.

Occupancy rates – 24-hours consulting or treatment rooms - KBCN1258

The default occupancy rate for 24-hour consulting or treatment areas in hospitals and care homes is 0.07.
Published pending reissue of the technical manual UKNC2014/REISSUE UKNC2018/REISSUE
03.11.2021 Issue 2.0 of the UK RFO technical manual amended.

Parking integral to development’s use - KBCN1145

Dedicated on-site parking which is integral to the function of the development can be excluded from the calculation of parking capacity. Examples could include, but are not limited to: The spaces are only to be used for this purpose, and must have appropriate signage and / or markings.

Parking spaces with electric car recharging stations - KBCN00044

Electric car spaces should be included in the total number of car parking spaces calculation for maximum car parking capacity. Whilst electric cars provide benefits in terms of reduced emissions, they do not directly reduce congestion which is one of the aims of this issue.

Public car parks - KBCN00092

Any public car parks in the vicinity of the assessed building, for which the building owners/operator are not providing some form of subsidy or an agreement with the car park operators to provide priority spaces for building staff, can be excluded from the assessment.  

Retail/Industrial showroom assessments - KBCN1178

For Retail/Industrial showroom assessments, Tra 04 is not applicable as suggested in the Retail/Industrial Showroom Appendix. In order to remove the applicability of Tra 04 for this building type on BREEAM Projects, please select any of the retail types of buildings under Tra 03, so that credits under Tra 04 become unavailable. Regarding the assessment of Tra 03, please continue to refer to the ‘industrial’ building criteria of the BREEAM UK New Construction 2014 technical manual as per Retail/Industrial Showroom Appendix.

Rounding the number of parking spaces - KBCN0602

Where the calculated number of car parking spaces is a fraction of a whole number, this should be rounded down to the next whole number to assess the issue. Fewer parking spaces are preferable as the more sustainable solution.  

Temporary Car Parking - KBCN0751

The number of car parking spaces should be based on the permanent parking spaces provided specifically for the development once fully operational. Assessors should determine whether parking spaces should be considered 'permanent' or 'temporary', based on evidence provided by the design team.

Visitor car parking spaces for Other Buildings (Transport type 2) - KBCN0242

For developments such as hotels and visitor centres, which have a relatively small number of staff and large visitor numbers, the guest/visitor car parking spaces do not need to be assessed for this Issue where these are separate from the staff parking spaces. However, if the staff and visitor’s spaces are combined (and not clearly segregated) then all spaces must be accounted for within the calculation for maximum car parking capacity. The aim of this Issue, 'To encourage the use of alternative means of transport...' is intended to apply to those commuting to the building on a regular basis.
21 06 2017 Wording amended to clarify the type of building and building-user covered by this KBCN.
