Connected Lighting - LED Technology

Connected Lighting: The Second Wave of LED Lighting Technology

For the past several years, building owners and managers who have converted to using LED lights have experienced the first wave of benefits provided by LED Lighting – energy savings. A well designed LED retrofit or tenant improvement project can cut energy consumption by 50% or more, reducing operating costs and improving net operating income.

The transformation from fluorescent or HID lighting to LED lighting can be viewed as a shift from analog to digital technology. The last significant device that shifted from analog to digital technology was the cell phone. Remember life before smartphones? Just 10 years ago, few of us imagined the breadth of applications that smartphones provide us daily. Today, few of us can imagine the breadth of applications that digital light fixtures will provide us in commercial buildings.

The second wave of benefits from LED lighting is approaching. This new technology, known as “Connected Lighting,” promises to provide building owners and managers the capability of controlling and tracking data, analytics, security, ambiance, and energy savings in their buildings.

Connected Lighting is a technology in which lighting fixtures are connected to an intelligence system that can communicate with other smart devices within a building, including smartphones and intelligent sensory devices. Connected Lighting holds the promise of truly smart buildings, and with that, an array of applications that will change the way we work and the way we operate and manage a building.

At Monterey Lighting Solutions, we are already seeing the first set of applications emerge based upon connected lighting. These include:

  • Space Planning: Utilizing smart Bluetooth beacons embedded in the light fixtures, the light fixtures can monitor and track the movement of people throughout a building. Analytics are then applied to determine how often rooms are used, the average number of occupants in a space and the length of time they are there. This information is very useful for corporate real estate executives for planning purposes, and also for building owners to understand which tenants may need more or less space.
  • Space Utilization – Again, using smart beacons within the light fixtures, real time information can be provided to users to determine open conference rooms or work spaces. The real time information is key because traditional room scheduling applications cannot determine when a meeting is cancelled, ends early or runs late.
  • Security – Geo-fencing systems can be created to identify when someone enters an area where they should not be. Because light fixtures are everywhere, there is an increased ability to monitor secure areas above and beyond what security cameras may provide.
  • Safety – In the event of an emergency, a connected lighting system can provide precise location information for every occupant in a building. The system can also be used to push alerts or instructions and provide turn-by-turn guidance (indoor GPS) for safe exit.  
  • Occupant Comfort – A smart connected lighting system can understand individual user preferences for workspace, light levels and temperature settings.  In a collaborative work environment, the system can identify which of their preferred workspaces is open. Once they arrive, light levels and temperature can automatically be adjusted to their preferred levels.

The second wave of LED technology, Connected Lighting, is on the horizon and coming towards us quickly. At Monterey Lighting Solutions, we encourage our customers to begin to look beyond energy savings or code compliance when upgrading their existing lighting to LED. This means not just when retrofitting a space, but also when performing tenant improvements. Many products on the market today already include the advanced communication technology that is required for Connected Lighting.  The cost differential is minimal.  The LED fixtures that you install in your building are likely to be there for 10 or more years. We believe our clients are well advised to understand the next wave of technology, and wherever possible, lay the proper technology foundation for advanced smart building applications.

Lighting Control Systems: The Importance of Setting a Building-wide Standard

For many building owners and managers, the decision on the lighting control systems used in tenant improvement projects has been left to the tenants. However, in the past few years, Title 24 regulations requiring continuous dimming, daylighting, plug load control and demand response have increased the cost and complexity of lighting control systems in commercial office space. The increase in complexity has led some owners and managers to begin to enforce building-wide standards.

Prior to Title 24 2014, lighting control systems were relatively simple. Therefore, the lack of standards had minimal impact on the operation of a building.  Today things are different. Controls systems have become much more advanced. Most control systems involve wired or wireless networking, and often include a software platform for configuration and management. Without an established standard, facilities managers and engineers are faced with an increasingly difficult challenge of supporting various control systems. A lack of a standard also prohibits the ability for advanced efficiency measures through building-wide control.

Increasingly, we are seeing a trend in which lighting controls systems are being considered as part of the building infrastructure, and in turn, building-wide standards are being set.

Establishing a standard for a fully networked lighting control backbone in commercial office space has the following advantages:

  • Simplifies ongoing maintenance and control of the space
  • Increases tenant satisfaction
  • Decreases energy costs
  • Optimizes efficiencies by tightly integrating lighting and HVAC controls Tracks each tenant’s energy consumption
Next Steps:

Lighting control systems from the leading manufacturers such as Acuity, Eaton, Philips, Lutron, Wattstopper, GE and OSRAM are advancing at a rapid pace. Each product has its own strengths and weaknesses. Evaluating which system is best suited for your building can be a complex task. Owners and managers are well advised to seek assistance from a neutral third party that is educated on the various lighting control platforms. The sooner the standards are set, the faster the benefits will begin to accrue.

Solar commercial LED lighting slotted for growth

Solar low voltage LED lighting products are expected to see more use in the commercial airport lighting market by 2016, according to a report from Research and Markets.

The Global Commercial Airport Lighting Market 2012-2016 report noted that solar LED lighting devices are among of the most suitable lamps for airports. Within this setting, they can be used for apron edge, obstruction, construction barricade and taxiway edge lighting applications in the airside areas of an airport.

"The increasing penetration and adoption of solar LED lighting is a major trend emerging in the Global Commercial Airport Lighting System market," said one analyst from the research team. "Currently, solar LED lighting systems are low-maintenance and easy-to-install lighting systems for airports."

Not only are solar LED lamps approved by the International Civil Aviation Organization, popular airports such as Chicago's O'Hare International Airport and Dubai International Airport already employ these lighting solutions. Due to a larger volume of global air traffic, it is expected that more airports will make the transition. As new airports are built, a larger number of people travel by air, thereby increasing the number of planes in the air and the need for efficient commercial lighting in these settings.

Solar lighting and outdoor lighting
LED lamps already provide significant reductions to energy usage. With the addition of solar panels, they further reduce the electrical demands on airports, schools, warehouses and other facilities. As a result of their low voltage, they can get more use out the energy harvested from the sun, thereby making them a viable solution even if there are a few overcast days.

According to Forbes, there is also the advantage of not needing cabling or wiring for solar LED lighting devices – reducing the time and money needed for installation, a big advantage when trying to quickly retrofit several fixtures. Besides airside applications at airports, these green lighting solutions have already been implemented in many other roadway and outdoor area lighting applications.

Solar Novus Today reported that solar LED lighting is especially useful in remote locations that do not have dependable electricity. These lamps were installed in low income communities known as colonias in Hidalgo, Texas, a rural area on the U.S./Mexico border. To improve safety and security, lights were installed at local parks, bus stops and other areas.

"And now with our 4000K and 5000K products, you can bring the energizing feel of natural light indoors without sacrificing light quality and compatibility," Parker said.

A lamp for various needs
Soraa offers the Vivid 2 LED MR16 in a variety of configurations. They can be purchased in 12-volt and line voltage options, and there are 2700K, 3000K, 4000K and 5000K CCT variations. In addition to numerous choices for light quality, there are 10, 25, 36 and 60 degree beam angles. Furthermore, these efficient commercial lighting products are compatible with a wide array of dimming controls.

A unique brand
Soraa has carved a niche for itself with its full spectrum, gallium nitride on gallium nitride LED lamps. These products render every color of the rainbow and they excel in white rendering. In fact, in an independent study conducted at Penn State University, 90 percent of respondents preferred the white rendering capabilities of Soraa's products.
