Connected Lighting: An intelligent way to cut energy use

Connected lighting has been around for many years, but it is only during the last decade that its use has become more widespread. Advances in technology, rising energy costs and growing consciousness of sustainability issues have all played their part in accelerating its popularity, helping it to become the go-to solution for those seeking an effective lighting system which delivers reduced energy use.

Lighting is one of the largest contributors to energy use in buildings – commonly reported to account for up to 40% of total energy consumption in commercial buildings and to be one of the biggest causes of co2 emissions. Connected lighting systems are an effective way of reducing costs and energy use and therefore something all contractors should be able to offer.

In a connected system, light fittings are connected to each other using wireless protocols such as Wi-Fi, Bluetooth and Zigbee.

Forming an intelligent network, this connectivity provides users with the ability to control each fitting installed from a central point, offering an unparalleled level of precision over all lighting settings. From the timings of operation to the colour, brightness, intensity and combinations of lamps in use at any time, smart lighting enables the output of every individual light fitting within a building to be controlled and automated to the most minute detail, meaning that energy use is optimised to this exact level too. It removes the guesswork from energy management, providing tangible, measurable results.

For example, schedules can be pre-programmed so that lighting only operates at specific times of day or in specific areas of buildings that are in use. This targeted approach means lighting is only in use where it is genuinely needed. It also eliminates reliance on human intervention, thereby reducing the risk of lights being accidentally left on and wasting energy.

Connected lighting can also respond to real-time conditions which again helps to moderate energy use. Paired with motion sensors that detect when a space is occupied, lighting can become instantly responsive, activating when someone enters the area and switching off again when it is empty. Similarly, daylight harvesting fittings can be used to automatically dim artificial lighting output when it is not needed. They measure the amount of natural light in a space and adjust output accordingly to maintain optimal illumination levels without unnecessary energy use. This approach not only saves energy but also creates a more comfortable environment by maintaining consistent light levels throughout the day.

It sounds simple but the impact an effective connected lighting system can have on energy use is considerable and is something contractors should be actively promoting to both residential and commercial customers. Having statistics available such as the capability of reducing lighting energy consumption by up to two-thirds can be very persuasive.

Connected lighting systems are leading the way in energy management in the built environment. And, in an era where sustainability is imperative, they are a great platform for contractors to demonstrate expertise and offer valuable savings to their customers.
