Grant Lush, head of marketing and client services at OTM, says it pays, both financially and environmentally, do to some number crunching.
At home, we know it's best practice to switch off lights when we leave the room, to change to energy-saving bulbs and not to leave the TV on standby.
At work, no matter how good our energy saving initiatives, we have to leave the company on standby. For example, in an IT-driven company like ours, the servers are always whirring away supported by their cooling units.
To understand just how much energy is being used, or wasted, we use the half hourly data available online from our electricity provider. This is really valuable data. It can focus the mind and raise such questions as what was burning electricity on Saturday night, Sunday morning or even Christmas Day.
If you're really clever you can relate usage to production output at specific times of the day, week or year.
We relied on such data when we targeted reduction of energy wasted during weekend closedown.
Over a year, we measured a set period of 6pm Saturday to 6am Sunday – a time at which there is never any overtime working to skew the usage figures.
Through improved close-down procedures, investment in aircon timers and other initiatives, we achieved a reduction of 34% and a knock-on affect to annual usage.
The Carbon Reduction Commitment scheme is targeting companies whose electricity is measured through half-hourly meters, which will highlight where this data is available.
There are also schemes available, for a fee, where all your utilities can be monitored remotely and analysed for you.
However you do it, it pays to do a little number crunching.
