Energy-efficient Lighting Controls: Enhancing Efficiency And Savings – Despite their immense potential to increase energy efficiency and advance smart building goals, network lighting controls (NLC) have yet to reach their full potential due to several factors increasing the wider and faster adoption of this emerging technology.
The energy-saving promise of NLCs was highlighted in a 2018 DLC study which found that adding NLCs to LED lighting projects could increase energy savings by nearly 50 percent. It helps to consider this in the context of the power savings of LEDs themselves – a technology that has changed the world lighting market over the past decade. According to the Department of Energy’s (DOE) most recent report on LED adoption in the US, the use of the technology delivered energy savings of nearly 470 trillion Btu in 2016, and reduced energy bills by approximately $4.7 billion. LEDs now dominate residential lighting markets and are making steady progress in the commercial and industrial sectors (although C&I market uptake is still below 13 percent, leaving lots of potential energy savings on the table). By 2035, the DOE predicts LEDs will make up 86 percent of all lighting products in the US – saving electricity equal to the total consumed annually by 45 million homes and reducing energy costs by nearly $52 billion.

Energy-efficient Lighting Controls: Enhancing Efficiency And Savings
LEDs are the key tools being sought to reduce the energy consumed by buildings and the associated GHG emissions. And the addition of NLCs makes the development of ignition an even bigger game-changer. According to a 2018 DLC report, the potential additional energy savings from the addition of NLCs to commercial LED plants over five years amounts to 75 terawatt hours (tWh) of electricity – about 17 times greater than the 4.5 tWh annual Hoover Dam output. What’s more, those savings appeared to persist for a decade or longer.
Data Center Optimization Solutions
As we seek more and better data to promote wider adoption of this important energy efficiency strategy, DLC and the Northwest Energy Alliance (NEEA) have launched another study to update the 2018 findings. The purpose of this one-year project is to accelerate the adoption of NLC systems and services by providing priority savings information, encouraging growth in utility by supporting programs that are expected to reduce NLCs costs.
The project’s contractor, Energy Solutions, will collect data from NLC systems for a variety of building formats, including offices, warehouses, health facilities, educational institutions, restaurants, retail establishments and manufacturing sites. Since the types, sites, and control of the building were represented more than in the 2018 study, the new study (planned for release in 2020) will investigate the best operational practices to achieve even higher energy savings through LED with NLC projects.
The data and analysis from the “Networked Light Control Energy Characterization Study” will be used directly by NEEA, DLC member companies of utility and efficiency institutions to promote the development and expansion of the NLC program, to encourage them to ask for the quantity and validity of their energy; establish incentive levels, and determine the cost-effectiveness of the program.

Light fixtures can save – and money – by automatically turning off lights when they’re not needed, by reducing light levels when it’s not at full brightness. It is necessary, or otherwise, to arrange the lighting in and around your house.
Before purchasing and using any lighting controls, it is useful to understand the terms and basic principles of lighting. It also helps to explore your indoor and outdoor lighting options if you don’t already have one. This will help narrow your reading.
The dimming controller lights the variable shade and can be operated manually, or with timers or sensors.
Coping With The Crisis: Increasing Resilience In Small Businesses In Europe Through Energy Efficiency
Dimmers are generally inexpensive and can extend the life of certain types of light bulbs, and provide some savings when the lights are used at a reduced level. But when dimming an incandescent light, it reduces the light, or brightness, more than the wattage, which makes incandescent bulbs less effective as dimmers.
Many light emitting diode (LED) bulbs can be used as dimmers, but they must be designed for dimming. Packaging or accompanying instructions will indicate if the product is dimmable.
Unlike incandescents, CFLs do not become less efficient when dimmed. Some CFLs are compatible with standard dimmers, which will be indicated on the package. Others require special ballasts and dimming bulbs. Fluorescent dimmers are built-in bulbs as well, which offer even greater savings than regular fluorescent bulbs. Dimming a CFL that is not designed to work with a dimmer switch is not recommended, as this can significantly reduce its lifespan.
Motion sensors automatically turn the lights on when they detect motion and turn them off shortly after. They are most useful for the security and utility of outdoor lighting.

Because utility lights and some security lights are only needed when it’s dark and people are present, the best control method can be a combination of a motion sensor and a photosensor.
Sensors are used to detect occupancy activity in a certain area. They offer the convenience of turning on the lights automatically when someone enters the room, and only by turning on the room lights, or reducing the light in an empty space. Occupancy sensors should be located where the occupants or occupants will detect activity in all parts of the room.
Ultrasonic sensors detect sound, while infrared sensors detect heat and motion. In addition to controlling ambient room lighting, they are used for functional lighting applications such as kitchen counters. In such applications, the function lights are turned on by the movement of a person washing dishes, for example, and automatically turned off after the person leaves the area.
You can use photosensors to prevent lights from working during daylight hours. This can help but remember that you don’t have to turn off your lights.
Lighting Control System
Photosensors sense ambient light conditions, making them useful for all types of outdoor lighting. These light-sensitive controls may be less effective inside the home, because lighting needs may vary with occupational activity rather than ambient lighting levels. They took many nights, yet they have this built-in feature that makes them efficient and easy to use.
Timers can be used to turn the lights on at certain times. Manual timers plug into the electrical outlet to control objects such as lamps or light strings. Programmable digital timers, which look like digital thermostats, automate refrigerator or outdoor lighting.
Programmable dimmers are not often used for outdoor lighting because the timer can often be replaced with a seasonal variation in the length of the night. But they can be used effectively with other systems. For example, the best combination for aesthetic lighting might be a photosensor that turns the lights on in the evening and a timer that turns the lights on at a certain time of night (such as 11 p.m.).
Useful for indoor lighting, timers are useful to give an empty house inspection. However, they may have limited use in a busy home because they do not respond to changes in your day-to-day activities.

Timing controls work well with LED and CFL light bulbs because they do not interrupt the circuit. This is especially true with manual frets, which use pins for occasional positioning. When using a programmable digital timer, check the package label to make sure it is compatible with the type of lighting you want to use.
