As performance increases and costs decline, light-emitting diode (LED) lighting is poised to become the predominant light source in the United States. Meanwhile, adoption of integrated advanced lighting controls continues to grow.
A marriage is happening. Light-emitting diode (LED) lighting and controls may soon be inseparable. While popular in offices, the combined benefits of efficiency, lower cost and building-operation analysis are extending to other workspaces.
In April, ELECTRICAL CONTRACTOR was at Lightfair, the biggest convention of lighting companies and innovators. Lighting is a dynamic industry, and the way in which it is integrating with building systems and technologies indicates a greater trend.
The World Wide Web connects 10 billion devices and counting into a global network. Any network-enabled device can establish a link to the internet, raising the potential to join building systems appliances and more.
While the light-emitting diode (LED) has gotten a lot of attention in recent years, another revolution has quietly developed in the background: intelligent (digital) lighting control. The future of lighting is solid-state, and it will be highly controlled.
With cities and utilities worldwide upgrading to light-emitting diode (LED) lighting for streets and outdoor areas, owners and installers wonder when they will build in the controls for smart-city applications.
Multifunctional sensors, networked wireless controls accessible from mobile devices, and, yes, light-emitting diodes (LEDs) are trends that picked up steam this year. These interconnected technologies will be transformational for the electrical contractor (EC).
With national emphasis on energy reduction in the commercial sector, the use of lighting-control technology represents a key means of enhancing building efficiency. At the same time, the evolving field of lighting controls has become increasingly complicated.
While wire and electric power delivery will remain a constant, the marriage between the two is being redefined. Wireless lighting and energy control are expanding from homes to office, healthcare, institutional and industrial settings.
In the healthcare-lighting arena, the improvements and increasing affordability of light-emitting diode (LED) products, along with advancements in lighting control technology, enable creative lighting designs that benefit patients and staff members.
daylight harvesting control systems have become a common feature in green buildings, and with ASHRAE/IES 90.1 2010 now the baseline energy design standard, it also is expected to become a staple in mainstream construction.
Joel Spira, who founded Lutron Electronics Co. in 1961, invented the first solid-state dimmer in 1959. For decades after, dimmers were largely used to control the aesthetic environment. Only in recent years has dimming become an important part of the energy costs saving debate.
The next step is to develop the basis of design or design intent, which can be expressed using two best practice tools. The first tool is the lighting control narrative, a document that describes how the intended control system will satisfy the owner project requirements.
According to the Office Building Energy Use Profile report from the Environmental Protection Agency (EPA), space conditioning and lighting account for 70 percent of all energy consumed in a typical office building with an additional 20 percent of energy consumption used to power office equipment.
