What is dMEV ventilation?

dMEV stands for decentralised Mechanical Extract Ventilation. It is a whole house ventilation methodology which consists of continuously running extract fans and background ventilators. Fans are located in every wet room and kitchen, running continuously at low trickle speeds to draw moisture-laden air out of the home.

Do you need trickle vents with dMEV?

“Where fresh air from the trickle ventilator(s) will be short-circuited by the dMEV unit, the wet area should not be fitted with trickle ventilators. Background ventilation should be made available by providing at least an 8mm undercut to the door that the wet area is accessed from, e.g. an en-suite off a bedroom.

Does PIV reduce humidity?

A PIV system can lower the humidity in the house, which can also prevent dust mite populations from thriving. As warm air rises, lofts are often comparatively warm spaces, and as this air is moved by the fresh air coming in, it can have a slight but significant impact on the temperature of the house.

What is positive input ventilation?

Positive Input Ventilation (PIV) is an energy efficient method of pushing out and replacing stale unhealthy air with drier fresh air by gently introducing filtered air into the home and increasing the circulation of fresh air around the property and improving the indoor air quality (IAQ).

What’s the difference between MVHR and MEV?

MVHR allows the recovery of a substantial part of the heat extracted by the ventilation thanks to a heat exchanger, while humidity sensitive MEV (or, more generally, a demand-controlled system) automatically reduces the rate of air renewal in order to limit heat loss as soon as the home is less occupied (which is …
