A DALI (Digital Addressable Lighting Interface) control system has been installed by Philips Lighting at pharmaceutical company Genzyme's operation in Haverhill Cambridge to achieve maximum energy saving by both presence detection and constant light senso
Genzyme Pharmaceuticals is a biotechnology company, which develops and markets innovative products and services designed to make a positive impact on the lives of patients with serious diseases.
Traditionally complicated, inflexible and uneconomic: Having the right environment in which to work in and carry out research is therefore of vital importance. Lighting can play a significant role here but more than this, by harnessing lighting via control systems the energy saved can be reinvested in ongoing research development programmes. In an age of global warming there is also an ever-growing need for greater commercial accountability towards responsible energy usage. In the past, however, traditional switching and control systems have proved complicated, inflexible and uneconomic. With the advent of DALI (Digital Addressable Lighting Interface) control systems have now become a more viable proposition.
The DALI system fitted the bill perfectly:
Thomas Holgeth, Design Director for High Technology Lighting Ltd, the scheme designers and luminaire suppliers commented: “The performance specification from the project M+E consultants Clean Design was exacting, as they have extensive worldwide experience of working for biotechnology companies, and have built a reputation at ensuring that clients' M & E systems are optimised. This particular project's lighting design remit ranged from testing laboratories, video conference suites, to dinning rooms and high rack warehousing. We had to offer a range of luminaires and a compatible control solution that could cost effectively be re-configured if required. The DALI system fitted the bill perfectly."
As with many organisations today, Genzyme's operation in Haverhill Cambridge, is multifunctional. This meant that the lighting control scheme had to be flexible enough to compliment these differing functionalities as well as being easy to install.
Flexible, cost-effective room lighting control:
As Alan Beardsley, OEM Product Manager for Philips Lighting, explained, "The benefit of DALI is that it offers flexible, cost-effective room lighting control. It is based on individually addressable ballasts with switching and dimming functions activated via the control wire. This means luminaires on the same circuit can be controlled independently. In addition systems can be reconfigured simply whenever necessary, allowing easy layout changes without costly wiring alterations."
Genzyme's main objective was to achieve maximum energy saving by both presence detection and constant light sensors. The DALI room controller proved the obvious choice for these requirements since any desired combination of DALI sensors, whether movement, daylight or infrared, can be plugged in. Whatever combination is chosen, the sensors are powered by the controller, which automatically modifies the lighting to give optimum performance.
Cost-effective:
Daylight linking allows maximum use of natural daylight by dimming and even switching it off completely without disturbance to occupants. The light sensors ensure that the desired lighting level is maintained at all times and the wide dimming range allows all daylight levels to be matched. Movement detectors can automatically switch off lighting in unoccupied areas. These functions mean that DALI cost-effectively delivers the fully automatic switching and control as required by the client.
Should the office layout change or a refurbishment be undertaken, the DALI system can be easily adapted even after installation since the circuits are programmed independently of the wiring. Infrared remote control replaces vertical switch wiring, so no wiring changes are needed when layouts are altered. In rooms with multiple lighting circuits, such as meeting rooms, preset lighting scenes can be changed at the push of a button by remote control.
