ROB SHEPHERD explains why building management systems (BMS) and building energy management systems (BEMS) should be at the top of the list of ways to optimise energy use and save money, and reviews the opportunities this burgeoning sector offers forward-thinking electrical contractors

and £13bn by 2050.
Serious business For building owners, managers and occupiers, there is growing acknowledgement of the fact that monitoring and controlling energy use is the most effective way of making immediate savings. Christian Schiemann, LBU manager KNX/EWA
at ABB, comments: ‘As buildings create a significant amount of CO2
emissions, efficient and carefully
controlled energy use is vitally important. Also, continuous price rises are forcing companies to take a holistic view of how energy is supplied and used.’ However, while the number of energy conscious
companies is on the rise, there are still others that are seemingly happy to waste it. According to research by Ex-Or, 85 per cent of companies use unnecessary lighting, while 50 per cent leave lights on needlessly for up to eight hours a day. Jason Ng, the company’s
