ACOUSTIC test engineers have hit back at claims that introducing robust detail compliance methods for new energy efficiency regulations would trim developers' costs.
They claimed that on large housing developments contractors would be better off carrying out air leakage tests to check compliance to Approved Document Part L of the building regulations rather than using standardised building methods under the robust details scheme.
James Mitchell, managing director of Ipswich-based testing engineer Construction Performance Consulting, said: 'On sites with a large number of units it is more economical to carry out air leakage tests.
Using testing to prove compliance will, for most building sites, be inexpensive compared against the project value.' Mr Mitchell said: 'There are a host of added benef its of using air leakage testing.'
