BT

Good call for energy savings! WEMS International’s wireless building energy management system will save BT a massive 22% of its energy usage across approximately 2,000 telephone exchanges.  The programme is being rolled out over sites ranging from 400m² to 17,000m².

Every month this saving equates to 60,060 tonnes of CO²…

…equivalent to the weight of 80,080 public telephone boxes.
