(2) how many schools have been found to be non-compliant with Building Bulletin 93 for acoustic conditions (a) in 2008 and (b) since Building Bulletin 93 came into force.
(3) how many schools have been tested for the quality of acoustics (a) in 2008 and (b) since Building Bulletin 93 came into force.
The Department does not have any figures for the numbers of schools that have adopted alternative performance standards, as permitted by Clause 1.2.1 of BB93. However many new schools use Clause 1.2.1 to inform some minor aspects of the acoustic design.
All new school designs and major refurbishments are required to comply with the Building Regulations Part E on Acoustics. This quotes BB93 as the normal means of compliance. Checks for compliance with Building Regulations are made by Local Building Control Bodies and records on the levels of non-compliant schools are not held centrally.
BB93 recommends that the client requires acoustic performance tests to be conducted but testing is not required for Building Regulations compliance.
