Using our KNX lighting control system, McGills installed a single 30V bus line throughout the library extension, as opposed to a conventional hardwired solution that would have used multiple cables.

"We probably saved about 20% labour time using the KNX system."
“A conventional hardwired solution would have involved multi-core cabling throughout the building, all being terminated into one central grid switching unit. Apart from the logistics of terminating several cables into the correct switch, there is no flexibility to change specifications during the build. Any change in switching control would involve extra cabling.”
Using our KNX each input and output device is assigned an address and then programmed so certain lighting circuits only respond to signals from particular switches. Individual circuits can respond to more than one switch, so an infinite number of switching variations are possible using the system.
The bus system also makes it easy to check the emergency lighting. Someone simply switches off all the lighting circuits to simulate a mains failure for a walk test.
Says Sutherland: “We probably saved about 20% labour time using our KNX compared to conventional hard wiring. More importantly, however, the system gives us the flexibility to change or add to the specification without having to run new cabling throughout the building.”
The new extension provides students with IT and WiFi facilities, integrates other libraries into one central building and provides additional room for research.
