3 ways to maximize energy savings with lighting controls

In this blog post we show you 3 ways to maximize energy savings with lighting controls. Why? Because at enModus we want to ensure there isn’t a single watt of wasted energy from any light anywhere in your facility.

To achieve that feat we need to consider the 3 main principles of energy efficient lighting:

  1. Use a high efficiency light source
  1. Only illuminate areas when lighting is required
  1. Emit exactly the correct amount of light

Replacing your legacy lights with energy efficient LED luminaires is a great place to start. In the graph below we show HID (High Intensity Discharge) luminaires were replaced with LEDs. Subsequently, the energy usage was reduced by 61%.

Additionally, the use of lighting controls creates even more opportunities to eliminate wasted energy. A recent article in ‘Buildings‘ references a study noting “adding connected lighting controls to LED installations boosts energy savings by an average of 47% beyond savings from LEDs alone.”

Likewise, our real-life example using an enModus Smart Connected Lighting (SCL) solution achieves a further 60% energy savings through lighting controls.

How to Maximize Energy Savings with Lighting Controls

Measurement and calculated savings validated by Carbon Trust

We work with the UK’s Carbon Trust on a number of smart connected lighting installation case studies to gather quantifiable energy savings. And so we defined 3 key lighting metrics deliberately intended to be ‘working pattern independent’. Above all this enables true, like-for-like comparisons to be made on any project.

  1. LED Savings Factor (LSF) – The energy saving of the new LEDs vs the old lights with no controls.
  2. Control Savings Factor (CSF) – The additional energy savings, achieved through lighting controls, of the remaining LED energy use.
  3. Total Savings Factor (TSF) – Combined saving of the new LEDs and the controls compared to the old lights.

How to Maximize Energy Savings with Lighting Controls

We can typically achieve Controls Savings greater than 50%. These higher savings cannot be replicated through localised light switches alone.

Let us show you how we do it. Our Smart Connected Lighting (SCL) solution uses Wattwave® power line communications and our Cloud Platform.

Firstly, our solution continuously adjusts the lumen output of individual LED luminaires. This ensures exactly the right amount of light is provided where and when it is needed.

Also, a constant stream of real-time data, delivered by Wattwave, is sent back to the Cloud Platform for visualisation and analysis.

This creates even more opportunities to increase energy savings. By using the control manager functions within our Cloud Platform users can optimise lighting schedules and schemes of individual luminaires.

3 ways to save energy with Lighting Controls

Specifically, we use 3 ways to save energy with our smart lighting controls.

DAY LIGHT DIMMINGOCCUPANCY DETECTIONTOP TRIMMING
Buildings with natural light can take advantage of daylight dimming.

Using Ambient Light Sensor (ALS) data inputs we continuously adjust the lumen outputs of individual luminaires.
Very few buildings use 100% of the space 100% of the time.

Users can aggressively optimise occupancy sensor triggers and switching of individual luminaires.
Regulate lux levels of individual luminaires.

Users can implement task-tuned lighting schemes and top-trimming to ensure lux levels are not exceeded.

You can only manage what you can measure

We use second-by-second reporting to give users real-time insights into lighting system performance. Thus control savings can only be maximized with a connected, real-time monitoring and intelligent lighting solution. Our reports include…

Energy use reporting

Our Cloud Platform visualises energy use against occupancy. For example, the occupancy data is shown as a blue line and energy use from the lights in yellow. Consequently, users can quickly identify energy saving opportunities where the lights are on but no one is present.

Energy savings reporting

Also, our Cloud Platform allows users to view control savings. Furthermore, saving are segmented by ambient light, occupancy and top trimming. As a result, users can easily visualise and quantify their energy savings from smart lighting controls.

Which buildings can save the most energy from lighting controls?

Our Smart Connected Lighting solution works best at large industrial and multi-buildings facilities of any construction type. As a rule, these buildings typically have many high-wattage lights in use for more than 12 hours per day. Hence these users can save more energy with a Smart Connected Lighting solution.

Because our solution is robust, secure and industry hardened it can be used with thousands of lights on a single installation. What’s more, because we use the existing mains power lines it can communicate distances of 1km without fear of dead-spots or interference. And finally, all this can be installed with minimal disruption to your everyday operations.
