Abbey Consultants – BREEAM Multi-Residency – Update

Following a number of related queries on acoustic testing frequencies required under HW11 (BREEAM Multi-residential 2006), the BRE have confirmed that the number of tests set in Table 2: Frequency of testing required refers to the number required for each type of test (i.e. airborne and/or impact sound insulation) to be conducted on each group or sub-group. The table does not give a total number of tests to be carried out on each group or sub-group.

For self contained dwellings,  Robust Details (RDs) are accepted as a method of compliance with Hea 21 (Multi-residential 2008) and can now be applied retrospectively to HW11 (Multi-residential 2006).  It should be noted that not all RD’s will demonstrate compliance with the performance levels required for Code/EcoHomes/Multi-residential credits as they have been designed to comply with the standards in Building Regulations.

The Robust Details scheme is not applicable in the assessment of constructions which fall into the categories of material changes of use or rooms for residential purposes.
