Sound Testing to ECO Homes Standard
Eco Homes is a Housing Corporation initiative run by the Building Research
Establishment which has Eco points available for sound insulation performance
detailed in the "Health & Well Being" section of the document.
The
credits are awarded on a sliding scale and depend on the amount of testing
carried out i.e. 20% in order to achieve 1 credit or 30% for 2 credits
& above and also the performance of the sound insulation itself over
the full test sample i.e. ADE 2003 performance standard for 1 or 2 credits,
ADE 2003 performance standard +/- 3dB for 3 credits, ADE 2003 performance
standard +/- 5dB for 4 credits.
The
Guidance - 2005 / Issue 1.1 March 2005. Up to 7.52% of the total
Eco Homes credits can be achieved by proof of performance testing demonstrating
higher levels of sound insulation are present in the build construction
of the development. See of the Eco Homes "Rating Prediction Checklist".
This
is very important as Housing Corporation funding will be linked to the
performance of the property, with the "Very Good" standard being
brought in as the standard to be achieved starting in the 2nd Quarter
2006. NOTE: Robust Details have no status under the Eco Home banner and
all sound insulation testing has to be carried out by Accredited
companies.
Service
is designed to assess the sound insulation performance of a building prior
to conversion to allow only the areas which require sound insulation treatment
to be identified and the amount of treatment to be specified. This service
can also be tailored with a test room to allow proof of performance testing
to be carried out on sound insulation systems before they are globally
applied in a property.

Assessment Criteria
Credits are awarded for achieving higher standards of sound insulation
than those given in Approved Document E of the Building Regulations and
demonstrating it by either using post-completion testing (called pre-completion
testing in Approved Document E and in the text) or Robust Details as follows:
