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?
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. (more…)
