CN1 is applicable to more projects than simply Part 1 only assessments (as stated in the Technical Manual). It states where a Part 1 only assessment cannot demonstrate full compliance with the criteria defined in the relevant tables, 1 credit is available (unless multi-residential) where an SQA completes the tasks listed within CN1.
Instead of being relevant to Part 1 assessments only, this text is actually relevant to any assessments which include Part 1, and do not include Part 4.
This covers the following combinations of Parts:
- Part 1 only assessments;
- Part 1 and Part 2 assessments;
- Part 1 and Part 3 assessments;
- Part 1, Part 2 and Part 3 assessments.
Please note: In relation to projects which are not multi-residential, one credit is available where the project demonstrates compliance through CN1 for ‘indoor ambient noise and sound insulation’, and one credit available where the project demonstrates compliance through CN1 for ‘reverberation times’.
