A thermographic camera has been used in the offices of the Norwich Evening News to identify where business energy savings can be made.
The camera, which detects heat sources and displays them on a monitor, revealed that computer monitors, unused phone chargers and even water coolers were generating more heat energy than might have been expected.
Around £1.2 billion worth of business energy is wasted every year in the east of England and corporations can address the problem by seeking energy-efficient office equipment and turning off electrical items when they are not needed.
Lester Marshall, health and safety manager at Archant Norfolk, told the paper: "We certainly need somebody to be an energy marshal or champion. I'm convinced we can make a 20 per cent saving on our electricity alone by monitoring it and getting people to turn things off when they are not needed."
Domestic energy-saving techniques are often not taken to the office as staff lack the incentive to pursue business energy savings.
The Carbon Trust recently launched a campaign to reduce national business energy costs by £1 million a day.
