LIGHTING TECHNOLOGY


Ledvance’s Vivares lighting control system can help provide a more comfortable office environment


the quality of light has improved noticeably and the offices have become much more versatile. To deliver even greater


benefits when choosing a lighting management system, it is preferential to specify solutions from a manufacturer that has secured environmental credentials. For example, EcoVadis is an independent sustainability assessment platform, helping companies to identify and evaluate the effectiveness of their green practices across business operations and their supply chain. Ledvance has been awarded the


EcoVadis Silver Medal, a recognition achieved by around 15% of assessed businesses. The accreditation reflects performance in areas such as ethical and social practices, compliance with labour standards, environmental responsibility, and human rights.


Better management of commercial and office spaces


Switching to an LED lighting system is an excellent first step in any sustainability journey, says David Goddard, but there are even more benefits to be had by introducing a light management system.

T


he need for efficient, intelligent and environmentally friendly lighting has been well-documented. Outdated


lighting technology, such as fluorescent and incandescent bulbs, are being successfully phased out. LED technology has paved the way for a more sustainable future with regard to lighting.


While this is an important element of


any drive for sustainability, maximum energy savings can only be achieved by using lighting control, and as such has the capability to further decrease energy consumption by 50%. Of course, not all lighting control


systems are created equal. Therefore, it is important to look at the different elements that make lighting control more appealing, both from an installation and usability perspective. Looking at the quality of the


components is an important place to start. After all, top systems need top components. Looking at the


30


Vivares system as an example, Dali components have been utilised. The Dali-2 certified control units, sensors and pushbutton couplers come in a new design and with extra functions, and are a perfect match for our Dali luminaires. Furthermore, they perfectly integrate with other Dali systems in the market.


Ease of installation When considering installation, choosing a plug and play solution offers significant benefits, such as that offered by our Vivares system: the technology is ready to use – simply wire the control in and it’s ready to go. The control units work for single rooms, with an area of up to 300m2 and up to 25 luminaires. Adding to this simplicity, Vivares


offers pre-programmed functions for manual room lighting – on/off, dim, TW and memory. No app, software or registration is required, making the system easy to get started with.


Connected to effi ciency An additional consideration is to embrace a cloud system, which allows for access to the data of your lighting system from anywhere. This has the capability to make systems such as Vivares even more efficient, reliable, energy-saving and cost-effective. By


choosing a platform with an intuitive dashboard, users can monitor energy consumption, the operating hours of the drivers and the relevant lighting data, among other things. This analysis then allows for a wide


variety of functions and actions, such as adapting the maintenance cycle of the lighting to actual demand, which will reduce unnecessary maintenance costs. Furthermore, settings can be selected so error messages are emailed to operators if the driver temperatures are too high, the DALI line is faulty or the control gear is defective – allowing for faults to be diagnosed from any location. Showcasing the benefits of light management systems in commercial settings, we recently completed a project with European construction company Valda & Partner GmbH. The organisation wanted to modernise the lighting in its offices in a listed building in Winterthur with an efficient, flexible and interactive light management system. We believe we have the ideal


solution – the wireless Vivares Zigbee including Biolux LED panels. The system offers comfortable handling, efficient energy use, automatic adjustment of the lighting level to daylight and individually adjustable light profiles. Since the modernisation,


Wellbeing advantages Adding to the sustainability advantages of a light management system, this technology has the potential to aid wellbeing when offering human centric lighting (HCL) capabilities. Little daylight, dark floors and


artificial light around the clock are working conditions that are quite common in office buildings. A system such as Vivares uses human centric lighting to adapt the lighting in open- plan offices or on entire floors to the natural changes in daylight using a certified algorithm: automatically, intelligently and easily controllable. That means that everyone in the building will benefit from the positive effects of HCL light.


With the right light at the right time,


HCL creates a working environment that simulates the changes in natural daylight with its visual, biological and emotional effects. To achieve this, the luminaires are controlled by an intelligent control system with appropriate light profiles. Through colour temperatures and illuminance levels, human centric lighting can simulate the course of natural daylight in such a way that it provides positive support for the human circadian rhythm (our ‘inner clock’). A neutral or cold white light colour, for example, can energise in the morning, whilst warm white light is relaxing and ideal for the evening. HCL supports health, well-being and performance in a workplace, which aids productivity and can also lead to lower sickness and abs ence levels. By specifying lighting management


systems that deliver a plethora of benefits, a sustainable future that also creates comfortable environments is an easy reality to achieve. ■
