What is Demand Control Ventilation & Why Use It?

The Varming Consulting Engineers Ltd. team is well versed in all established and emerging building design methods that have been applied on countless projects over the years. In this blog, we’re here to tell you about Demand Controlled Ventilation and what it’s designed to do in residential projects 

Demand Controlled Ventilation Explained

Essentially, Demand Controlled Ventilation (DCV) is a highly-controlled method of ventilation control that uses occupancy levels to determine the amount of fresh air that’s provided. This system is able to constantly monitor the quality of air inside the home, keeping an eye on metrics like levels of carbon dioxide (CO2), humidity (H2O), as well as harmful volatile organic compounds (VOCs).

DCV guides the air flow rates in line with these fluctuations, delivering increased flow when levels are high and reducing it when air quality is deemed to be sufficient. This allows for optimum ventilation while using the minimum amount of energy to do so.

The Numerous Benefits of Using DCV include...

  • Exceptionally low running costs

  • No condensation/mould problems due to zero user interaction

  • Suitable for both established and new buildings

  • Extremely quiet running (25-30 dB)

  • No requirement for filters

  • Improves security due to lack of need for open windows

The Varming building design team used DCV technology at the recent Ard Cre Ballymoneen project in Galway completed earlier this year. The €2,600,000 commission was for Galway City Council and involved the installation of M & E services for 78 residences.
