Mechanical Extract Ventilation Are you constantly fixed or… demand controlled?
MEV with constant airflow During the day In the morning High energy losses Exhausted airflow remains high No variation of airflow
MEV with constant airflow In the evening After work No variation of airflow
MEV with constant airflow At night High energy losses
MEV with demand controlled airflow
MEV with demand controlled airflow During the day In the morning Extracted airflow decreases High energy savings Adjustment of airflowto reduced humidity High energy savingsall day long
MEV with demand controlled airflow After work High energy consumption during a short period of time Adjustment of airflows based on humidity in each room Extracted airflowboosted with human activity
MEV with demand controlled airflow After work High energy consumption during a short period of time
MEV with demand controlled airflow In the evening Airflows andenergy consumption still vary with occupants’ activity
MEV with demand controlled airflow Shower Airflows andenergy consumption still vary with occupants’ activity
MEV with demand controlled airflow At night Extracted airflow and energy consumptionslow down …and increases slightlyin the bedroom Airflow decreases inempty rooms when pollutants are extracted… High energy savingsall night long
MEV with demand controlled airflow At night High energy savingsall night long
