How Smart Lighting and Motion Sensors Are Reducing Energy Costs in Homes and Workplaces

Lighting is responsible for a large proportion of energy use in buildings. Estimated at around 10% in homes and up to 40% in warehouse and industrial sites, it is one area where the adoption of more efficient technologies can translate to major savings.

As energy bills continue to rise, finding lighting solutions that balance performance, efficiency and affordability has never been more crucial.   Fortunately, advances in lighting control and automation mean achieving impressive energy savings is now simpler and more accessible than ever.

Motion Sensors

A great place to start is with motion sensors, which ensure lighting is only in use when a space is occupied.

Typically, there are two main types of motion sensor technology in use: Microwave and Passive Infra-Red (PIR).

Microwave sensors work by using a principle known as the ‘Doppler Effect’; emitting continuous low-level microwave signals across a designated space which reflect off objects and return to the sensor. Any changes in the signal pattern caused by movement activate the sensor and trigger the lighting system, providing illumination as needed.

PIR sensors on the other hand, detect infra-red radiation. When a warm body (such as an animal or person) enters the sensor’s range, it causes a change in the infrared radiation levels, which triggers the sensor and activates the light.

Both types of sensors work extremely well but PIR sensors are more commonly used in homes, whilst microwave sensors are generally used in commercial spaces and outdoors due to their greater sensitivity and wider coverage.

Smart Lighting: The Gold Standard

When it comes to energy efficiency, smart lighting is the standout solution.

Enabling every single lighting detail to be precisely programmed and automated, smart lighting supports users in tailoring their surroundings to their specific needs and routines. From operating times, to the colour, brightness, intensity and combination of luminaires in use, every individual light fitting can be programmed and controlled to the smallest detail ensuring energy is used only where and when needed and at the optimum level for comfort and productivity.

With options ranging from smart bulbs, strip lighting and smart plugs, to fully connected systems, the range of smart lighting products now available is vast and continually growing.

Light Monitoring Dashboards

The latest addition to the smart lighting landscape are light monitoring dashboards. Ideal for commercial and industrial settings, these hubs take smart lighting installations to the next level by providing real-time data on performance and energy use.

Highlighting everything from occupancy patterns and brightness levels to energy consumption per fixture and temperature/environmental conditions around fixtures, this insight allows lighting systems to be monitored, managed and optimised like never before – transforming how energy efficiency is achieved.

They also make maintenance, management and reporting much simpler. With all lighting data stored centrally on the hub, accurate information is always at hand, allowing operators to monitor, manage, and optimise lighting environments with greater precision.

An Energy Efficient Future

As energy pressures continue to grow we know that the future of lighting technology will be increasingly focused on sustainability. These solutions will help achieve that — reducing consumption, cutting costs and supporting the move towards a lower-carbon future.
