Durable and resilient features – Features not present - KBCN1547

The requirements of Rsl 04 aim to minimize the frequency of building component replacement.  Options D, E and F relate to specific features that are vulnerable to damage through the building's operation. Therefore, if it can be demonstrated that an asset does not include any such features, this requirement can be considered met, because there is nothing to protect. Evidence confirming the above must be referenced and provided in the assessment. It is unlikely that Option C will not apply in a commercial asset. However, if an assessor believes this to be the case, they should contact BREEAM Technical with full details and justification.

20 Oct 2023 - Applicability to BIU V6 Residential removed - Options can be filtered out where not applicable.
14 Dec 2022 - Updated to include Options D and E, in addition to the reference to Option F.

Evidence of no risk – Use of Approved Standards and Weightings List - KBCN0959

The current BREEAM International Non-Domestic New Construction Approved Standards and Weightings List (ASWL) can be used as evidence to demonstrate that a country has ‘no risk’ to all natural hazards apart from flooding (which is considered within POL 02 of BREEAM In-Use 2015 and Rsl 01 of BREEAM In-Use Version 6). Any country which has a weighting of 0% for Hazards within the current ASWL can provide this to BRE Global as evidence. As flooding is not included within the Hazard section of the ASWL, it must be evidenced separately. Therefore, in order to achieve maximum credits within MAT 05 or Rsl 03, the assessment must also provide evidence that the asset is in a ‘low or zero flood risk area’ under the requirements of POL 02 (BREEAM In-Use 2015) or Rsl 01 (BREEAM In-Use Version 6). Note: BREEAM In-Use International Assessors who are not BREEAM International Non-Domestic New Construction Assessors, will be unable to access the ASWL. In this instance please send a technical query to BRE Global outlining the country which the asset is located, and BRE Global can confirm the current weighting for that country. This KBCN does not apply to BIU assessments under BREEAM NOR or BREEAM SE

29-Nov-2023 Clarification - N/A BREEAM NOR/SE 
01-Oct-2022 Updated to apply to BREEAM In-Use Version 6
16-Aug-2016 Amended to clarify situations where there is no access to the ASWL

Flood risk – use of flood maps only in FRA - KBCN1524

Answer option E (Commercial) or F (Residential) If a flood risk assessment considers flooding from rivers and seas only, flood risk is zero / low, and the following requirements are met:

• There are local or national flood maps available covering these sources of flooding.
• The maps are accurate, up to date, and have sufficient detail to clearly identify flood risk for the asset.
• The maps are approved by local or national government, and based on robust data.

It is acceptable for the flood risk assessment to be carried out by a relevant member of the team. It does not require a competent individual (see manual definition) to do this. Most sources of flooding are site-specific and require specialist input and calculation to quantify. However, flood maps meeting the criteria above can provide an acceptable level of assurance of overall flood risk from rivers or seas without the need to engage a specialist. Answer option C Where the risk of flooding is medium or high, flood mitigation measures are required (criterion 3). These mitigation measures must be defined by either:

• A local authority (the measures must be relevant to the asset).
• Or a competent individual.

The FRA can still be produced by a relevant member of the team. Exemplary credit This option is only available if a site-specific FRA was carried out by a competent individual, and cannot be based only on flood maps that give an allowance for climate change. Example scenarios [accordion] [accordion_block title="Low / zero flood risk"] National flood maps cover flooding from rivers and seas. The flood risk from these sources is zero / low. The compliant FRA can be produced by a relevant member of the team. [/accordion_block] [accordion_block title="Medium / high flood risk"] National flood maps cover flooding from rivers and seas. The flood risk from these sources is medium / high. Flood mitigation measures are required. The local authority provides some general flood mitigation measures for the area, but these are not relevant to the assessed asset. Instead, a competent individual is consulted on relevant flood mitigation measures for the asset - their recommendations are recorded in the FRA. The compliant FRA can be produced by a relevant member of the team. [/accordion_block] [/accordion]

Intruder alarms – Requirement for these to be audible when activated - KBCN1597

Where it is justified by the security consultant, project team or building management that a 'silent' intruder alarm system is more suited to the asset’s overall security strategy, this can be considered as meeting the Definition in our guidance.

Risk assessment – flooding is the only natural hazard - KBCN1552

Where:

• Flooding is the only natural hazard identified and,
• The flood risk assessment (FRA) from Rsl 01 is used as evidence for this issue,

then Answer D ('the asset is in an area where no risks exist') is only available where the FRA shows zero or low flood risk from all sources of flooding. Assessing flood risk from rivers and seas only does not cover all risks.
