Scottish Government DMEV Research

Anderson Bell + Christie were commissioned by Scottish Government Building Standards Division as part of a team led by MEARU to research Decentralised Mechanical Extract Ventilation.

This research established if new build dwellings fitted with dMEVs in moisture producing rooms, coupled with a reduced area of trickle ventilation in apartments of 2,500 mm2, can maintain satisfactory IAQ throughout the habitable rooms of dwellings.

The findings would suggest that whilst there are some situations where a dMEV system can assist with the ventilation provision of modern airtight homes, the ability to act as a whole house system is limited, particularly in larger more complex layouts, and where ventilation loads are high.

Issues to consider therefore include:
