Mechanical ventilation with heat recovery in new homes: final report

Ventilation and indoor air quality task group (Zero Carbon Hub)

Over the past three years, the VIAQ Task Group has been reviewing the health implications that can be associated with poor indoor air quality, against a background of new homes becoming much more airtight. Specifically we have reviewed current practice in relation to mechanical ventilation with heat recovery (MVHR) and evidence from homes in which it has been installed. This is the final report of the VIAQ task group, providing evidence to support the interim report published by the Zero Carbon Hub in January 2012.
