Craig DiLouie, LC, CLCP recently interviewed Scott Ziegenfus, CEM, CLEP, CDSM, GGP, GPCP, LEED AP, Architect, Systems Manager, Government and Industry Relations at Hubbell Lighting, for an article for the January 2019 of ELECTRICAL CONTRACTOR, the official publication of NECA. The topic: why and how lighting professionals should talk to IT departments.
“As the lighting industry attempts to morph from its conventional role of illumination and become more of a provider of smart networks that collect data through chips and sensors embedded in the lighting infrastructure, it should focus its sales efforts on IT groups rather than on the customary facilities departments,” Mark Halper writes for LEDs Magazine.
“While the majority of installations today are distributed high voltage (between 110V and 347V), the emergence of solid-state lighting technology has brought into question whether this is the most practical and efficient way to feed future lighting systems … In general illumination application, there are currently two core approaches to operating luminaires directly from low voltage DC power. Emerge Alliance 24VDC distributed, and Power over Ethernet (PoE). The two approaches employ distinctly different control approaches.”
Networked control and connected luminaire manufacturers are now promoting their products as “IoT enabled.” This means when the IoT does arrive, the lighting system will stand ready to play a part in it without significant additional cost. The converse may also be regarded as true, which is without connected lighting, any new LED lighting may instantly become obsolete after installation.
In this guest post, Paul Rudalavage, Synergy Electrical Sales summarizes five key areas to understand and explore when purchasing a lighting control system.
“If you are a regular reader of Lighting Controls Association blog posts, then you know that networked lighting control systems (NLCs) are really computer networks – they just happen to control luminaires, occupancy sensors, photosensors and light switches. The paradigm shift for lighting control systems has occurred at lightning-fast speed in recent years … However, once you decide to piggyback onto an existing IT network, you are in the domain of the IT staff who works for the building’s owner.”
The California Lighting Technology Center recently announced publication of the Daylight Harvesting for Commercial Buildings Guide, which provides guidance towards meeting and exceeding California’s Building Energy Efficiency Standards for daylight harvesting.
FACILITIES MAINTENANCE DECISIONS recently ran an article contributed by the Lighting Controls Association on how to apply lighting controls to existing buildings.
Software plays a central role in commissioning, operating, and analyzing data collected by networked lighting control systems. As connected lighting becomes more popular, manufacturers continue to make their software simpler, more robust, more portable, and require less training. Software is a major touch point regarding the lighting control system serving either as a platform or an integral part of implementing the Internet of Things in commercial buildings.
“I recently wrote about how lighting energy allowances under current codes are now approaching a practical minimum, thanks to significant improvements in source efficacy, optical efficiency, and controls that automatically extinguish lighting when it is not needed.”
