The U.S economy grew by 2.5% in 2017, outpacing 2016, and is expected to produce similar growth in 2018. A major contributor to the economy is construction, and the outlook for construction spending in 2018 overall is positive, particularly nonresidential. The AIA’s semi-annual Consensus Construction Forecast, a survey of the nation’s leading construction forecasters, is projecting 4% growth in nonresidential construction spending in 2018 and 3.9% in 2019.
The California Energy Alliance (CEA) has announced that its code change proposal dedicated to improving the lighting control requirements for lighting alterations was accepted by the California Energy Commission (CEC) in its recently published Draft Express Terms. CEA’s code change proposal includes simplified language with reduced application and/or project-specific requirements; an easy-to-understand energy savings option for small buildings and tenant spaces; and a universal compliance threshold and set of exemptions.
Craig DiLouie recently interviewed Greg Rhoades, Director of Marketing for Leviton Energy Management Controls & Automation, about voice-controlled lighting
This guest article by Steve Mesh compares the pros and cons of room- versus building-based control systems.
While installing controls in new construction or full-scale remodeling is reasonably straightforward, retrofitting controls into an existing building or space can be somewhat problematic, especially when cutting into walls and ceilings is undesirable. To this end, the first step in assessing an appropriate approach is to establish what the goals of a retrofit are. Pure energy savings gains can be realized with simple ON-OFF controls additions, while inclusion of dimming functionality requires greater investment. Embracing more complex targets, such as inclusion of human factors driven lighting strategies are even more involved.
The National Electrical Manufacturers Association (NEMA) and The Industrial Internet Consortium (IIC) agreed to enter a formal liaison to advance the Industrial Internet of Things (IIoT). A liaison relationship between IIC and NEMA fosters common understanding of new technologies for the digital economy.
Controlling plug loads is a natural fit for the lighting controls industry, as the same devices and strategies are used for automatic shutoff of plug loads such as task lighting as for general lighting. This feature article by LCA Education Director Craig DiLouie, LC, CLCP looks at energy code requirements, compliance options, and control types.
Craig DiLouie recently had the opportunity to interview Michael Deschamps, Product Marketing Manager, Philips Hue, Philips Lighting US. The topic: voice control for lighting.
The general concept of the Internet of Things (IoT) is expansive and virtually without limit. The basis of the technology is that devices, appliances, building systems, computer networks, vehicles and personal smart devices become connected together in such a way as to exchange and process information or facilitate integrative control functionality. The impact this will have on industries and individuals is potentially profound.
In this LCA column, Kevin Willmorth looks at the Internet of Things and the role lighting is likely to play in it.
Power over Ethernet (PoE) lighting is part of a brave new world. The ascendance of LED fixtures has given rise to some new methods of providing and controlling light in our environments. Since LEDs are low-voltage devices that use direct current, they are a good match with a system that provides low-voltage DC power over Ethernet cables. Guess what? That’s a computer network! For several years, lighting (and computer) companies have been developing the idea of powering LED fixtures from what is essentially a computer network switch. As you might imagine, this gives rise to a host of questions about a variety of issues.
In this LCA column, Steve Mesh takes an in-depth look at power over Ethernet (PoE) systems.
