Lighting is one of the most expensive costs to a business, accounting for more than a third of a building’s electricity use and CO2 emissions. It’s therefore understandable that many companies and facilities managers are looking towards innovative smart control solutions to manage electricity and lighting usage. However, with the focus still firmly on the light source itself and as energy prices drop, are we actually considering the true cost of our lighting?

Light bulb technology is constantly evolving, with modern LED lights using up to 90 per cent less energy than regular halogen bulbs. However, a more recent demonstration of innovation within the light bulb sector was actually surrounding the incandescent bulb. Disregarded and banned several years ago for its inefficient properties, the incandescent light bulb for most will be a ‘blast from the past’. However, Massachusetts Institute of Technology has developed a new technique that could, in theory, boost the efficiency of the bulb by up to 40 per cent. This would result in a bulb three times more efficient than the best LED or CFL bulb currently on the market!
These developments show that as technology within the lighting sector continues to evolve, the energy consumption of the light bulb itself is becoming less of an issue. What is becoming more apparent is the ‘parasitic’ energy consumption of the control solution that controls the lights. This refers to the amount of energy used by the control system even when all of the lights it controls are turned off.
As dimming or switching off lights when a room is unoccupied can reduce electricity consumption by 30 per cent, lighting controls present significant benefits. In some instances however, this saving is diminished due to the energy that the control system itself is consuming.
In addition, as the cost of energy has lowered in recent months, other important factors such as flexibility, real-time access to device level data as well as employee health and wellness are becoming more apparent.
By making smart investments with money currently being saved through reduced energy bills, building owners can guarantee all of the factors are met.
The latest generation of control solution providers are ensuring flexibility, data access as well as reducing the energy consumption of their systems, to pass on all benefits provided by the control system to the building owner.
An example of such a system is elitedali™ lighting controls. The elitedali technology enables lighting to be incorporated into the building’s existing building management system (BMS), reducing installed equipment and providing the ability to leverage the latest energy harvesting technologies for switches and sensors.
With the ability to halve total lighting energy consumption, elitedali controls contribute significant energy savings, whilst accounting for less than one per cent of the building’s energy use.
Furthermore, as the elitedali system has been created with the Internet of Things in mind, the system can be controlled both locally and remotely via any suitable web browser and smart mobile device. This enables instantaneous changes, such as switching lighting on/off and dimming as well as providing real-time access to device level data for each lighting fixture.
Requiring less of an initial investment due to it simply connecting with the already installed BMS, elitedali smart lighting controls are ideal for reducing lighting electricity use, protecting against parasitic energy consumption as well as providing complete access to the lighting control system and it’s data.
