© Aereco 2010 Constant MEV KW In the morning During the day No variation of airflow Exhausted airflow remains high High energy losses MEV with constant airflow

© Aereco 2010 Constant MEV KW After work In the evening No variation of airflow MEV with constant airflow

© Aereco 2010 Constant MEV KW At night MEV with constant airflow High energy losses

© Aereco 2010 MEV with demand controlled airflow

© Aereco 2010 Savings Aereco MEV KW Constant MEV KW In the morning During the day MEV with demand controlled airflow Extracted airflow decreases Adjustment of airflow to reduced humidity High energy savings all day long High energy savings

© Aereco 2010 Savings Aereco MEV KW Constant MEV KW After work MEV with demand controlled airflow Adjustment of airflows based on humidity in each room Extracted airflow boosted with human activity High energy consumption during a short period of time
