2.0 Errata

Greenfield/Brownfield site – Definition - KBCN1259

For the purposes of this Issue, the following definitions apply: Greenfield site A site which has never been built on, includes minimal development or which has been substantially cleared of all buildings and associated fixed surface infrastructure* and has subsequently remained undisturbed for five years or more. * Typically, the site includes less than 5% residual development by area. This supersedes the definition of 'Greenfield' for this Issue in the technical manual. Brownfield site Any site which does not fall within the above definition of 'Greenfield site'

Manual errata – up to V6 – prediction of operational energy consumption and minimum standards - KBCN1602

The technical manual refers to ‘4 credits for prediction of operational energy consumption’ as one of the requirements for achieving either Excellent or Outstanding minimum standards. This reference to 4 credits is incorrect, and will be removed in a future update. This is to make it clear that the requirement for Simple Buildings is for achieving the 'Prediction of operational energy consumption' criteria, not achieving four credits.

08-Nov-2023 - Title updated. Wording clarified.
26-Jun-2023 - This errata KBCN separated from KBCN1336.

Proposed development – definition for use in assessment - KBCN1255

The correct definition to use for the assessment of LE01 is 'Proposed development'. The definition of 'Development footprint' will be removed and Criterion 1 clarified in the next re-issue of the technical manual.

Robust Details – Testing requirements - KBCN1251

For self-contained dwellings, which form part of a Multi-residential assessment, compliance can be demonstrated where the use of constructions for all relevant building elements have been registered with and assessed and approved by Robust Details Limited (RDL) and found to achieve the performance standards required for the number of credits sought. Robust Details (RDs) are construction solutions that provide an alternative to pre-completion sound insulation testing as a method of complying with Requirements E1 of Approved Document E (2003 Edition) of the Building Regulations (England and Wales), DOE Technical Booklet G - Sound 2012 (Northern Ireland) and Technical Handbook Section 5 - Noise, 2013 (Scotland). The relevant plots on a development must be registered with RDL and built in accordance with the RD specification. To give a reasonable level of assurance that these details will achieve the required minimum standards, RDL carry out random inspections during construction and random sound insulation tests after construction. A Robust Detail is deemed to be approved for BREEAM (Multi-residential building) credits only when it achieves a specified performance level as assessed by RDL. Robust Details can only be used in relation to assessment for new build dwellings and cannot be used to assess the performance of construction details in rooms for residential purposes or material change of use.

Table 7.3 AI and number of points achieved - KBCN1362

The header for the table should read:

• First column: “Points required for projects with AI < 25”
• Second column: “Points required for projects with AI ≥ 25 < 40”
• Third column: “Points required for projects with AI ≥ 40”

Therefore, please ignore the text in the second column “(urban centre)”. For example, a project with an AI of 30 that achieves 4 points for implementing options in Table 7.4 would be awarded 6 credits.
