Human Centric Lighting Gives World Class Skiers an Edge

World-class athletic competitions held at night are pretty unusual. Once the sun slips beyond the horizon, the athlete’s performance curves slip -- a consequence of evolution. What are athletes supposed to do? They have to compete at their highest levels at the very time when their bodies are preparing for a night of slumber.

Why Human-Centric Lighting is the New Prescription for Eldercare

How often have we heard a frazzled parent explain a teenager’s irritable mood on lack of sleep? We all know that sleep plays a critical role in our mood and our levels of concentration and alertness. Through numerous research studies, we now know that quality of sleep also affects long-term health and overall wellbeing. Poor sleep is linked to physical problems such as a weakened immune system and mental health problems such as anxiety and depression. 

Best Practices for Using PIR Sensors

This post is the second of a 2-part introductory series on Passive InfraRed (PIR) sensors. In part 1, we highlighted how PIR sensors detect motion, discussed the importance of the sensor lens, and the different types of motion that can be detected.  Here we look at proper sensor placement and setting accurate sensitivity levels as well as how to reduce false triggers and sensor time-outs.

Smart Lighting Control Systems are Solving Real-World Problems

LED lighting has come a long way from its initial days. Today it is combined with digital lighting controls to create smart lighting solutions that dramatically save on energy consumption and the related operating costs. But in addition to these savings, organizations deploying smart lighting solutions are achieving impressive results in other ways. Let’s take a look at a few examples.

What are PIR Sensors and Why Do I Need Them?

Passive InfraRed (PIR) sensors are widely used in smart lighting systems and save money by dramatically reducing lighting usage and energy consumption. They are employed in offices and classrooms as well as in spaces with intermittent and unpredictable lighting usage such as corridors, stairwells, storage areas and parking garages. Lights can be programmed to either “dim” or “switch” in response to an occupancy status signal from a sensor. The strategy also improves comfort for occupants as they never have to enter a dark area or manually turn lights “On” or “Off”.  

Human-Centric Lighting Takes LED Technology to the Next Level

The human body reacts to sunlight and darkness by releasing hormones that direct our internal clock, known as our circadian system. Disturbing our internal clock can affect our ability to perform or concentrate and literally puts us at risk for a host of diseases.  Recent research indicates that building occupants’ circadian rhythm can be disturbed when they spend long hours indoors without access to the Earth’s natural lighting cycle.  

Tackling Commercial Office Plug Load

Building owners and facility executives are always looking for new ways to control energy costs. Plug loads significantly impact an energy budget—sometimes accounting for as much as 50% of the total energy consumption in commercial spaces, and there are no-cost and low-cost solutions that can tackle the problem.

Smart Control Strategies for Lighting and Plug Load

Advances in lighting technologies coupled with building code requirements have resulted in a sharp decline in the amount of electricity used for lighting commercial buildings. Despite that success, there is still room for substantial improvement. The most recent report by the Commercial Buildings Energy Consumption Survey (CBECS), says that lighting still accounts for 17% of all electricity consumed in U.S. commercial buildings. 

Manufacturer Adopts Smart Lighting System: Cuts Area Brownouts

A large manufacturer with over 1.3 million square feet of space uses a significant amount of power every day. During peak periods when energy usage was high, the local area was experiencing brownouts and the local utility company approached the manufacturer with incentives to reduce their hours of operation during these times as a means of avoiding a brownout situation.

Three Ingredients for Personalized Lighting in the Workspace

People crave a personalized experience--from the coffee we order in the morning, to the online shopping sites that ‘know’ our preferences, to the vacation tours we find when browsing travel sites that are a ‘match’ with our bucket list. It’s no surprise that promises of ‘a personal experience’ are touted everywhere and widely encouraged. We’ve come to expect it in all aspects of our life.
