A recent report by Campaign for Clean Air in London (CAL) highlighted the lack of understanding among senior managers and others that few buildings comply with indoor air quality standard EN: 13779. Buildings may have mechanical ventilation, air conditioning and/or air filtration or none of these and few buildings comply with indoor air quality standard EN:13779.
In London for example many Local Authorities do not know if their buildings comply and many Local Authorities do not know about compliance in their schools and that significant opportunity exists to improve indoor air quality and reduce energy costs.
So what can I do?
Ask Camfil Farr for an ‘Opportunity Assessment’ this will help you:
- Understand the system condition of your Air Handling Unit (AHU)
- Request a report at no cost that proposes an itemised solution
- Choose the best solution using low energy air filters
- Give your existing AHU plant a new and efficient lease of life
- Reduce running costs and get peace of mind
Follow this simple checklist:
- Use easy access mountings and ensure seals are effective
- Use low energy glass fibre bag filters, with high surface area, rather than synthetic or ultraviolet type filters to extend life and reduce energy cost
- Use carbon filters to reduce gaseous pollutants
- Consider upgrading fans as current ones may be energy inefficient
- Clean cooling coils and heat exchangers
- Clean air handling units and duct systems
- Use pressure gauges to monitor on-going filter efficiency
- Regularly maintain the system and establish operating practices
Finally you should ask Camfil Farr to certify your building as complying with EN 13779.
