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 …
