Indoor Air Quality Assessment
With the following services, we can assess your situation, measure your current air quality and review your air quality infrastructure, such as HVAC and IAQ sensors.
IAQ monitoring equipment can be provided on either a temporary or permanent basis. The key parameters measured are Carbon Dioxide (CO2), (TVOC) Particulate Matter (PM2.5), Temperature and Humidity.
Air distribution diffusers in a ceiling may or may not be providing sufficient ventilation. We can verify the amount of air being delivered from each diffuser using a balometer. This verification can then be used to calculate the air change rate in your space.
When inheriting buildings, the amount of outdoor air being supplied to the space is often unknown. We are able to validate this by taking duct traverse readings immediately after the AHU. This will allow you to assess if you are providing enough air changes, or ventilation per person.
It is important to verify how even the air distribution is in a space. When the building was completed, this should have been sorted at commissioning, but over time, the system can fall out of balance for a variety of reasons.
We carry out a survey to assess the major components of your Air Handling Unit. Fans/belts/coils/dampers are checked and photographed as well as assessing the hygiene and corrosion levels within the unit.
Assessing a buildings heating ventilating and air conditioning system requires professional assistance. We will survey the system to see if it is operating efficiently and to see if any optimisations can be made.
We can supply and fit mains or battery powered CO2 sensors. These can either be standalone systems with visual and audible notifications or networked monitors with long-term data logging to demonstrate a commitment to safety.
A BREEAM air quality plan details how your building will ensure good IAQ from a combination of source control during construction and best practice guidance for how a building should be operated in order to maintain good IAQ.
CFD computer modelling can be used to demonstrate air movement, air velocity and residence time. This has been of renewed interest during the pandemic. We can provide this service for new and existing buildings.
