Working with the Carbon Trust was very illuminating. Through their expertise and my desire for the centre to become more energy efficient we identified a number of areas that could be improved.
Mark had worked with the Carbon Trust at his previous workplace, so when he wanted to explore ways of making the shopping centre more energy efficient, he knew who to call.
Implementing the Carbon Trust’s suggestions so far saves the centre 43,000 kWh – £4,000 per month at today’s prices. But according to Mark that’s just the beginning: “We are continually working to reduce our CO2 emissions even further.”
Actions taken
The centre is heated by air handling units (AHUs), which heat and circulate air around the building using the existing ventilation system. These were regularly in use for longer than they needed to be. We suggested making sure the operating hours of the AHUs matched the opening hours of the centre, reducing the amount of energy wasted. It was also found that some ventilation units were unnecessary, and as a result the centre was able to switch them off altogether.
As Middleton Grange had already planned to focus on the lighting, Mark asked the Carbon Trust for advice specifically looking at how this area could be improved. The existing internal tungsten-halogen floodlights were removed, as they consumed large amounts of energy without adding much to the lighting levels.
The centre also swapped the light fittings for more efficient alternatives, and installed passive infrared sensors (PIR) so that the lights are now only used when needed. It has also developed a simple, one-page environmental policy statement for staff throughout the centre to use.
Looking to the future
Middleton Grange has since been awarded the Green Environmental Standard for Property Management by EcoPerspective, which works with businesses to reduce their environmental impacts. The centre is currently working towards the Gold Standard.
Future plans to continue the suggestions of the Carbon Trust include insulating the pipes throughout the building to retain heat, and an ongoing training programme to raise awareness amongst staff of their contribution to energy efficiency. "Through these measures we are running a more cost effective business and dramatically reducing Middleton Grange’s impact on the environment."
