Changes to CCS – January 2022 - KBCN1500

UKNC2011, UKNC2014, RFO2014 and Domestic Refurbishment 2014 schemes: In response to the 2022 changes to the structure and scoring in the CCS, the adjusted points for credits are as follows for each of the three new sections (Community, Environment, and Workforce): One credit requires a minimum of 9 points per section and 27 overall. Two credits require a minimum of 11 points per section and 35 overall. Exemplary credit requires a minimum of 13 points per section and 39 overall. UKNC2018, UKNCV6, HQM ONE and HQM V6 schemes and UKNCR V6.1: No changes have been made to the criteria or the requirement to demonstrate compliance with items g, p and q for the exemplary credit. GN33 has been updated to demonstrate the mapping of the updated CCS to these schemes, see KBCN1215. For assessments not following CSS, the criteria remain unchanged. More information on the changes to the CCS scheme are outlined on the CCS website.

Construction Energy Use & Construction Water Use – Weekly reporting - KBCN1387

03 Detailed monitoring and reporting Crit 3 Conduct the monitoring and reporting of data in crit 2 on a weekly basis. The reason to ask for data recorded on a weekly basis, is to collect much more granular data which can be potentially overlaid with the project plan. By undertaking this it would enable the construction team to better understand the most energy intensive processes which could be targeted with energy efficiency measures.

Contractor not yet appointed at the design stage – Site waste management - KBCN000002

Where the contractor has not been engaged at the design stage certification, it is acceptable to award the credits based on a commitment. This commitment must be from a suitable member of the design team, and must detail the targets and criteria which must be met. Evidence must also confirm that the details in the commitment will form part of the contractual requirements. Note: This does not apply to the requirement for a pre-demolition/pre-refurbishment audit, which must be undertaken at Concept Design Stage.

Evidence for ’04 Detailed monitoring and reporting’ at design stage - KBCN1232

The evidence requirements associated with ‘04 Detailed monitoring and reporting’ for Design Stage in both the 'Construction Water and Energy Use' are incorrectly formatted and should appear in the Post-Construction Stage column. For design stage evidence requirements, please refer to KBCN1231 'Design Stage evidence requirements when a contractor has not been appointed'

GN33 – Evidence requirement clarification - KBCN1157

In Guidance Note 33 (GN33), BREEAM recognised responsible construction schemes are mapped against the 'Responsible construction management' criteria within the manual, in order to determine the degree of comparability. Table 2 in GN33 provides a mapping of the recognised schemes, the relevant scores and the BREEAM items ‘a-s’ which are achieved. Where items in the table have been 'ticked', the only evidence that is required is confirmation of the formal certification under the relevant scheme, in addition to the evaluation report. No further information is required to achieve these items. Where an item in the table has been 'crossed', this means that either, the responsible construction scheme does not demonstrate compliance with that BREEAM item, or that the score achieved is not high enough to confirm compliance with the item. Where a cross exists against an item, additional evidence will be required to demonstrate compliance with those items, (where credits are sought).
