Homeowners say 'Oui' to controlled mechanical ventilation
In France, 90% of new homes are fitted with a controlled mechanical ventilation (CMV) system, which enables them to meet heating regulations that specify the minimum flow rate for air extracted from buildings.
Several French manufacturers are now specializing in the design and manufacture of CMV systems, and are continuously improving them. It could be a technology worth examining in the United States, where tight buildings and poor IAQ are gaining increasingly more attention.
