2. Service and maintain air conditioning units

Air handling systems will clog up over time, which reduces their efficiency. Make sure filters are replaced and the equipment is serviced regularly.

• Fact: The cost of servicing air handling equipment will easily pay for itself two or three times over before the next service.

3. If you have refrigeration equipment...

Check the rubber seals on doors and replace those in bad condition – damaged seals waste energy.

• Tip: If possible, any fridges or vending machines that are near to a direct heat source should be moved.

4. Maximise the use of space in refrigeration

Consider whether you can consolidate items into fewer fridges or freezers, but make sure air can still circulate. It’s also important to regularly defrost freezers to ensure good circulation.

• Tip: If you have refrigerators or vending machines that only contain non-perishable goods, install low cost timers so they automatically switch off outside of operating hours.

5. If you’re a manufacturer, walk around your site and listen out for compressed air leaks

Air leaks waste huge amounts of energy and can be easily fixed. It’s also good practice to check the pressure and investigate whether it can be reduced without affecting your process – just a 10% reduction could generate 5% energy savings.

• Fact: A single pinhead leak in a compressed air system could now be costing up to £2,000 a year in wasted energy.

6. Establish the optimum setting for all motors and ensure they are kept clean and regularly serviced 

Dirty equipment runs hotter, will operate at a lower efficiency and is much more likely to break down or seize up.

• Fact: Reducing the speed of a motor by just 20% can halve its energy consumption.
