S P E C I A L F E AT U R E intelligent buildings Building managers should think about smart wiring systems. Got to have a system Kevin Sheldrake at Carlo Gavazzi reveals why a unified approach to control services such as HVAC and lighting will consequently improve a building’s performance. I n the phrase ‘building energy management system’ the last word is frequently neglected. But a dictionary definition of the word ‘system’ is ‘a set of things working together as parts of a mechanism or an interconnecting network; a complex whole.’ And this points to the seriousness of thinking about the building energy management systems, or BEMS, as a single network. The big picture This idea that the building, and more importantly, the building services are a ‘complex whole’ is significant when trying to achieve long term energy efficient operation. A holistic approach to designing, installing and operating building services is something that the sector has been striving for over the past two decades. It’s not uncommon to experience building services working inharmoniously with each other for example; heating and cooling running concurrently and lights on at night when the building is unoccupied. The reality of our buildings is that they are often not systematic at all. A poorly designed system can increase carbon emissions unnecessarily and be unecono
