How does uncleaned ventilation systems increase energy consumption?

Thursday, July 29th, 2010

The Carbon Reduction Commitment (CRC) Energy Efficiency Scheme comes into force in September for companies/establishments whose annual electricity consumption exceeds £500,000 per year.  Can you tell us how uncleaned ventilation systems can increase this consumption?

Dirty Ducts

Dirty Ducts

HVAC can account for 70% of an organisation’s energy costs.  The Carbon Trust claims that poorly maintained and dirty ventilation systems can increase energy consumption by 60%.  This is the result of dirt and debris in the ducting and on the coils and filters clogged which put the main resistance on the fan.  The more the fan has to work to maintain the system’s operating efficiency, the more energy is consumed.  There’s a straight forward  message – clean the system, improve the filtration and not only will the air quality be improved but there will be a bonus in the form of energy saving.

Since the essential functions of a ventilation (air conditioning) system is to circulate clean safe air it is indisputable that those with a particular responsibility for maintaining ventilation systems should ensure that all possible steps are taken to do just that.

Unfortunately it is my company’s experience that, with some exceptions, ventilation systems are not being given the priority attention they deserve. Even against a background of greater focus on achieving improved cleanliness under the Government’s deep clean drive there is little evidence of ventilation systems being included in the programme essentially aimed at reducing the incidence of healthcare associated infections (HCAI).
