The installation of Ex-Or lighting-control modules in 55 London fire stations to date is typically reducing energy costs for lighting by about 20%. Ian Shaw, environmental and energy-efficiency office for London Fire Brigade, explains, ‘Typically, lighting accounts for around 70% of the electricity load at each fire station. The average lighting bill per station is £10 000. To date, we are achieving annual savings of £120 000. Once the entire estate has Ex-Or’s equipment installed, we will be making savings of almost £250 000 each and every year.’ [There were still 50 more stations to be completed.]
