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.
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.
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”.
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.
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.
Providing children a quality education is a national priority. Curriculum, school culture, teacher effectiveness, and test scores have long been used as measurements for school success and student performance.
It’s that time of the year! It’s time for our annual prediction list of top commercial lighting trends for the coming year.
Those that made our top 5 list for 2018 have broad impact across the commercial lighting industry. Each highlights how technology-driven the industry has become and indicates the direction we see lighting systems take as part of the broader smart building and IoT world. It’s going to be an exciting year!
Here at OSRAM we are constantly reading industry research and articles about the changing workforce and its resulting impact on commercial office space. We want to share with you some of the pieces we found to be most interesting on this evolving workforce.
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.
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.
