Ventilation Systems

A bit about Ventilation Systems

Office ventilation has become an essential part of the working environment. Ventilation systems are an essential component of any building, helping to maintain indoor air quality by removing stale air and introducing fresh air, keeping modern offices environment clean and healthy.

Building and Facilities managers will be changing the way they operate in maintaining the buildings in line with the H.S.E, CIBSE and Refcom recommendations. Ventilation in the workplace regulations are changing, with CIBSE recommending both air ventilation systems and air conditioning systems are maintained and checked more regularly. If at present the systems are maintained every 6 months, they recommend this is changed to quarterly maintenance / filter cleans.

Properly designed and installed ventilation can improve comfort levels, reduce energy costs, and prevent the buildup of harmful pollutants and moisture.

Tips for air ventilation systems

Irrespective of good practice, the volume of HVAC maintenance will increase and filters will have to be cleaned regularly. At Modern Facilities we can design, install and service workplace ventilation equipment.
  • Clean all filters within the workplace ventilation system.
  • Ensure the internal ductwork and AHUs are clean.
  • Increase the volume of fresh air and extracted air being supplied and removed from the building,  reducing the chances of any possible virus remaining within the office air.
  • Extend the operation times of supply and extract mechanical ventilation systems. Start ventilation at normal speed at least two hours before building usage time. Switch to lower speed two hours after the building usage time. Keep ventilation on 24/7 with lower ventilation rates when people are absent.
  • An on-demand system is when the ventilation is increased or enabled from an external source. This could be due to temperature, or generally a CO2 detector. When the ventilation system is using a CO2 detector, the fresh air increases when the workspace becomes more contaminated with Carbon Dioxide (CO2). Lower the CO2 detector’s setpoint to allow the systems to increase the quantity of air changes within the workspace.

Prevention

First and foremost your HVAC systems should be thoroughly cleaned and serviced to ensure they are providing the best conditioned environment possible. We suggest:
  • Thorough chemical cleaning of all HVAC equipment.
  • Remove airborne contaminants by making sure systems have correct filtering and are well maintained.
  • Regular maintenance.
  • clean ventilation.
  • Completing a deep chemical clean - to make sure no bacteria exists throughout your HVAC system.
  • Making sure regular maintenance is carried out - incorporating filter checking/replacing.
  • Change the settings on the heat recovery ventilation unit controllers to prevent recirculated air entering the building.
  • Ensure the internal ductwork and AHUs are clean.

FAQs

Here are some frequently asked questions about Ventilation Systems:
  • What are some signs that my ventilation system may need maintenance?
    Signs that your ventilation system may need maintenance can include reduced airflow, unusual noises, foul odours, or increased humidity levels in the building.
  • What does ventilation system maintenance involve?
    Maintenance of a ventilation system may include cleaning or replacing filters, checking for blockages, inspecting ductwork, and ensuring that the system is working properly.
  • How often should I have my ventilation system serviced?
    The frequency of servicing your ventilation system can vary depending on the type of system and its usage. Generally, it is recommended to have it serviced at least once a year.
  • Why is ventilation important in a building?
    Ventilation is important in a building to provide fresh air, remove stale air, control humidity levels, and prevent the build-up of indoor air pollutants.
