(credits building type dependent)
To encourage change of use projects to consider the provision of car parking in order to promote the use of alternative means of transport other than the private car to and from the building, thereby helping to reduce transport-related emissions and traffic congestion associated with the building's operation.
The following is required to demonstrate compliance:
Up to two credits - Car parking capacity
- The building's car parking capacity is compared to the maximum car parking capacity benchmarks in Table 39 and the relevant number of credits awarded.
For most building types, except those where stated, the benchmarks vary according to the building's public transport Accessibility Index (AI determined in accordance with BREEAM issue Tra 01 Sustainable transport solutions). Therefore, for these building types the AI must be determined prior to assessing this issue. This is required to ensure that the building’s car parking capacity is relative to the building's accessibility to the public transport network.
Checklists and tables
|Building's Accessibility Index||< 4||≥ 4 - < 8||≥ 8|
Max. parking capacity
1 space per x building users, where x is:
|Office, industrial, student residences and key worker accommodation||3||4||5||1|
|Sheltered housing, care homes and supported living facility||4||5||6||1|
|University and further education||15||20||25||1|
|Hotels and other short-stay accommodation||3||4||5||1|
|Preschool, schools, colleges and retail,||Issue not assessed for these building types|
|Applicable assessment criteria|
|Parts: 1, 2, 3 and 4||
This issue is only applicable when the building is undergoing a change of use, as a result of the refurbishment works.
Parking spaces set aside for the following building users can be excluded provided these spaces are dedicated for that use, i.e. sized accordingly with the appropriate signage or markings:
In the case of excluding car share spaces, the future building occupier will need to confirm they have an enforceable car share policy.
|Parking shared with other buildings||
Where the assessed building forms part of a wider site, e.g. campus, business park, hospital, and parking is not designated to individual buildings, then the assessor has two options:
|Criteria||Interim design stage||Final post-construction stage|
One or more of the appropriate evidence types listed in 4.0 The BREEAM evidential requirements section can be used to demonstrate compliance with these criteria.
|All||Where relevant, a completed copy of Tra 01 calculator confirming the building's Accessibility Index.||As per interim design stage.|
- Accessibility Index
- Refer to Tra 01 Sustainable transport solutions.
- Building users
- Where the term building users is referenced in this BREEAM issue it refers to the following, where relevant to the building type:
- Staff (who will work within the building)
- Students (who will access the building for work or study during a typical academic term time or semester day)
- Residents (who will reside permanently or for a short period of time in the building).
- Care homes
- For the purpose of BREEAM, care homes are defined as buildings with residential accommodation and meals, and have residents that require a level of personal care such as eating, cleaning and a level of medical care.
- Change of use project
- A change of use project is where there is a change in the purposes for which, or in the circumstances in which, a building is used. For example where the building becomes a hotel, where previously it was an office or where the building was previously a commercial building and is now a education building etc.
- Sheltered housing
- Sheltered housing can be defined as self-contained accommodation, usually with an emergency alarm system, communal facilities and a resident warden.

Notes for Table 40 of default occupancy rates:
- The net floor area for each function must be multiplied by the equivalent occupant density to determine an overall occupancy for the function area.
- Not all potential building areas are listed, only those required to reflect estimated building occupancy for the building type. For example, an office building may have a canteen but it will be the staff that predominantly uses the canteen. The office staff numbers will be estimated using the default occupancy rate for the office area; therefore to include the canteen would result in double counting of occupancy.
- If a building type is not listed, occupancy rates for a similar building type or function area may be used.
- The above occupancy rates have been sourced from the activity database of the UK Simplified Building Energy Model (SBEM).
