Advanced indoor lighting systems maximise energy-efficient LEDs

Developments in wireless technology have opened up a number of additional opportunities. It offers unrivalled flexibility and controllability to building managers who can monitor and control light output throughout a building from a single remote hub. This level of dynamic control can be extended from this single remote hub to multiple sites or multiple buildings allowing managers to oversee light intensity and energy consumption throughout all the properties under their jurisdiction and then giving them the tools to control it.

The wireless technology also allows engineers to monitor the energy consumption of each individual luminaire, or groups of luminaires, their light intensity and potential lamp failure to ensure that the most efficient maintenance schedule can be implemented whilst reducing engineer on-site time. These cost benefits are additional to the savings made automatically through reductions in energy usage.

As buildings become increasingly multi-functional, the requirements from occupants become more varied. Seldom does a building now house a single occupant; instead retail, residential, manufacturing and offices reside on the same site creating challenges to building managers aiming to optimise energy efficiency strategies, whilst at the same time meeting all the users' needs 24 hours a day.

Lighting will not be required at full intensity at all times in all areas, but determining the best lighting option has not always been an easy task, especially as people do not follow set patterns. Retail outlets are open longer and people work flexible hours. To meet these changing requirements, lighting systems have to be intelligent, adaptable, and customisable. Even within buildings, different areas often need different lighting. For example, the lighting required on the shop floor in a supermarket will be significantly different to that in the stockroom.

By using the detailed monitoring and analysis capabilities now available through the latest lighting systems, building managers have at their fingertips the data to implement a whole suite of energy saving strategies to optimise efficiency.

This data can be gathered automatically at regular intervals to give a broad overview of the whole system. Lighting can then be tailored to meet the specific requirements of each area, activity, and time of day. The new generation solutions are able to use the energy consumption data gathered to create a map of the whole complex, allowing managers to not only instantly alter the lighting in each area to suit the activity taking place, but also to generate and implement longer term energy saving strategies.

Intelligent solutions can use a number of energy efficiency strategies, often simultaneously, to reduce energy consumption. Photocell sensors can measure the amount of daylight in any given location and adjust the intensity of the electric lights to ensure optimum efficiency and light output. Occupants will be unaffected by these daylight harvesting operations, as small reductions are undetectable by the human eye.

Nevertheless, these reductions will deliver significant savings over time. Lights may be dimmed without impacting on human activity. Managers can see the dim status of all lights on the system from the remote hub and have the ability to return all lights to their full intensity at the push of a button when required. Further energy saving strategies include time scheduling, load shedding, and scene setting.

Intelligent new generation monitoring and control lighting systems allow for the delivery of a completely user-customisable dynamic lighting solution that will save money on energy and maintenance, whilst at the same time reducing carbon emissions.

Managers can implement a coordinated lighting strategy across their entire property portfolio, however complex or diverse, from a single building to multiple sites.

Seizing control of indoor lighting is one simple way in which a business can save money, energy, and reduce their carbon footprint. These benefits can be achieved without having any impact on business operations. With the installation of such a system, managers have complete control over the whole lighting output, whether this is in retail, residential, manufacturing, office-based settings, or a combination in a mixed-use development. Flexibility and adaptability combine with comprehensive monitoring and control capabilities to ensure a completely user-customisable indoor lighting system that delivers on every level.
