ASHRAE/IES 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings is published every three years to provide states and other jurisdictions with a model commercial building energy code. The 2010 version, published November 2010, represents the most dramatic revision of the standard since 1999. In this two-part series of special reports by the Lighting Controls Association, we will examine the new energy standard in detail. Part one, presented here, focuses on changes to the prescriptive lighting power requirements as well as changes to scope and administrative requirements. Part two, to be published next month, will focus on the standard’s extensive list of new mandatory and optional lighting control requirements.

The National Electrical Manufacturers Association (NEMA) commends the Federal Energy Regulatory Commission (FERC) for a recent decision that will improve the reliability and efficiency of the electric grid. In its final rule, FERC has allowed locational marginal price (LMP) to be paid to demand response (DR) resources in organized wholesale energy markets. This means that […]
Lighting Controls Association members will present “Design of Electric Controls for Daylighting,” a three-hour workshop, during the Daylighting Institute at LIGHTFAIR 2011.
Radio-frequency (RF) wireless communication is a significant emerging lighting control technology. In a typical hardwired lighting control system, control signals are sent using communication wires. In a wireless RF system, control devices communicate through the air using radio waves, eliminating the need for control wiring. The resulting advantages enable advanced lighting control with greater installation flexibility and lower labor installation cost, ideal for hard-to-wire applications non-accessible ceilings, hard ceilings, asbestos abasement issues, and brick and mortar existing buildings.
Wireless RF lighting control first became popularized in residential applications, with typical applications including home theater, kitchens and other common areas, master bedrooms and exterior and security lighting. In recent years, however, wireless RF lighting control has emerged as a viable alternative to hardwired controls in commercial building applications. What benefits does RF wireless communication provide?
The first benefit is flexibility. Wireless control devices can be placed where they are needed without limitation imposed by wiring, including areas that are difficult to wire. More flexibility is provided in unique applications. Electrical planning may be shortened. After installation, devices can be moved and the system expanded with relative ease.
The second benefit is labor and material cost savings, which may result in net installation savings after the typically higher product cost is figured. Wireless control eliminates the need for dedicated control wiring and associated switch legs, traveler wires and other raw materials. The system installs more quickly, producing labor savings. With no damage to walls or ceilings, and little to no disruption to business operations, wireless control lends itself well to existing building applications demanding the benefits of advanced lighting control.
The advantages of wireless control make these solutions particularly suitable for commercial building applications where the cost of running control wires is too costly or simply not possible, such as outdoor lighting, parking garages, warehouses and retrofits.
The National Electrical Manufacturers Association (NEMA) has published LSD 14 Guidelines on the Application of Dimming to High-Intensity Discharge Lamps. This white paper, last published in 2002, was produced by NEMA’s Lamp Section and is available for free download. LSD 14 provides guidance on the application, combination, and practice of dimming of high-intensity discharge (HID) […]
The Lighting Controls Association is pleased to announce that EE300: Lighting Control of LEDs, a key offering in the Association’s popular online Education Express distance education courses, has been updated.
While activity for institutional projects should hover near 2010 levels, there is likely to be a modest decline in commercial construction in 2011, according to the AIA Consensus Construction Forecast Panel. Overall nonresidential construction spending is expected to decrease by 2% for the year. The Panel believes 2012 will produce stronger gains, however, with overall building construction rising about 5%, with growth twice the rate of the more cyclical commercial sector. This construction outlook reviews the year’s top line construction numbers, shows where leading construction and electrical industry indicators are trending, and provides a summary of the latest AIA Consensus Construction Forecast for 2011.
