1.2.5 Verify the appropriate operation of timers of the ventilation system

1.2.5 Verify the appropiate operation of timers of the ventilation system


Verify the correct operation of timers in terms of control system depending on the level of occupation of the building. For example: stop during evenings and holidays, change the mode of operation depending on the occupation level and change the programming between winter and summer.


  • The energy consumption reduction potential is considered from low to medium. With this measure, a reduction in ventilation losses over 50% can be obtained on a building in which the ventilation is turned on all day

  • Provide better air quality for the building occupants

  • Reduce HVAC operating costs



  • Operation and Maintenance (O&M) staff size, skill level, and budget need to be considered

Economic assessment

The cost is low or even zero, since most of the actions are for the improvement of the control of ventilation systems, although it will depend in each case on the type and age of the ventilation system.
