While “circadian lighting” varies in definition, it generally refers to design that uses intensity and spectrum of light for a non-visual effect—namely, to support regulation of circadian rhythms. A new study suggests that by enabling intensity and spectral adjustment and optimizing exposure based on time of day, designers and owners can minimize the energy tradeoff imposed by associated typically much-higher light levels. This would entail use of an advanced lighting control system capable of scheduled dimming and perhaps spectral emission adjustment.
A U.S. Department of Energy-funded Pacific Northwest Energy Laboratory (PNNL) study found that hospital nurses value controllability in lighting and that this controllability can translate to greater satisfaction among patients.
The Northwest Energy Efficiency Alliance (NEEA) recently published a study seeking to compare one-for-one luminaire level lighting control (LLLC) retrofits with a comprehensive networked lighting controls (NLC) redesign. Conducted by the University of Oregon, the study found that a one-for-one LLLC upgrade produced comparable energy savings and lighting quality at a competitive cost.
With increasing frequency, lighting control systems are tasked to interoperate with other building systems such as building automation systems (BAS) to share information and automate building functionality. Ensuring communication and smooth interoperability is called integration, a potentially challenging undertaking during a project. This is the topic of a new Education Express course developed for the Lighting Controls Association by C. Webster Marsh, HLB Lighting Design.
This article, based on the Lighting Controls Association’s new Education Express course EE202: Automatic Plug Load Control, provides an overview of approaches used to automatically control plug loads in commercial buildings.
The U.S. Department of Energy’s (DOE) Interior Lighting Campaign is undergoing a fresh launch as the Integrated Lighting Campaign in June 2020. The program’s core goal of market transformation is the same, with many of the same services and benefits to participants, but the promoted suite of technologies is now going beyond LED adoption toward integrated systems. The Lighting Controls Association is proud to support this program as a member of its Organizing Committee and an inaugural Supporter.
The Lighting Controls Association is proud to announce the latest offerings in lighting controls from industry-leading manufacturers. Check them out!
Current stay-at-home regimes resulting from the COVID-19 pandemic has had a significant impact on how the construction industry works, including education, with online distance-education becoming more popular. The Lighting Controls Association is proud to offer Education Express, a free, robust series of courses covering all aspects of lighting control, including technology, application, design, and commissioning.
Reducing initial cost by an estimated 20-25 percent, rebates remain a strong incentive for investing in energy-efficient lighting and controls. In 2020, significant rebate opportunities are widely available for LED lighting and controls, including growing availability of rebates for networked controls.
The U.S. economy grew by 2.2% in 2019 and is expected to slow to 2% in 2020, according to the most recent forecast released by the Federal Open Market Committee Meeting on December 11, 2019. The slowdown in 2019-20 is considered a byproduct of the trade war. A major contributor to the economy is construction, and the outlook for construction spending in 2020-21 is positive but lower than 2019. The AIA’s semi-annual Consensus Construction Forecast, a survey of the nation’s leading construction forecasters, is projecting 1.5% growth in nonresidential construction spending in 2020 and 1% in 2021.
