LD+A Research Matters: Integral Metering & Reporting Capabilities of Networked Lighting Controls

03/29/2022
Networked lighting control (NLC) systems have proven they can successfully reduce demand and save energy in real-world applications through a combination of basic and advanced control strategies. However, the potential of NLCs’ integral metering and reporting capabilities to provide cost effective energy-use data for incentive programs and outcome-based code opportunities has not been fully realized. This is, in part, due to the variety of metering and reporting approaches used by today’s NLCs.

LD+A: Faces of the Future

12/01/2010

In 2010, LD+A compiled their list of “Future Leaders”.  LD+A editors reached out to more than 50 lighting professionals representing all corners of the industry and asked that they submit nominations. LD+A also contacted IES leadership at the Section level, as well as IES members involved in both the IES Emerging Professionals and Young Professionals Scholarship programs, for their feedback.  LD+A asked each of these people to recommend those with approximately five years experience who are on the cusp of leadership positions (e.g., technical, management, educational) in the industry. 

IES LD+A Research Matters: Smart Corridors Light the Way to Energy Efficiency

11/01/2011

If a light dims down to the minimum recommended illumination level in a secondary space and no one is around to see it, does it really make a difference? Research shows yes—it makes a big difference in reducing lighting energy use.

Laboratory and field testing of prototype systems that dim corridor lights down to 50% or less of full output during vacancy periods and increase to full output during occupancy show significant reduction in lighting energy use and great potential for effective electricity demand response.

LD+A Research Matters: A New R&D Center for Mexico's Lighting Industry

08/09/2021

In the fall of 2017, the Mexican Ministry of Energy awarded funding to the Universidad Autónoma de Guadalajara in collaboration with the University of California Davis to establish a lighting technology and design research center known as the Centro de Tecnología en Iluminación (CTI). This is a multi-year, public-private investment focused on addressing growing climate change concerns through translational research committed to clean energy and sustainability in Mexico.

8 Lighting Guidelines to Save Schools Money

06/09/2015

Pacific Gas and Electric Company— California K-12 school districts are in the process of updating and retrofitting the mechanical and engineering systems in their schools, primarily through the implementation of Proposition 39. Improving the efficiency of school lighting is a priority in the effort to increase the energy efficiency of school facilities, due to its relative simplicity in comparison to retrofitting complex mechanical systems.

High Color Rendering Can Enable Better Vision without Requiring More Power

03/02/2015

LEUKOS— A new article advocating for high color rendering in consumer lighting products and the policies that support their adoption is now available.  The paper is a collaboration between CLTC, the University of British Columbia and the National Research Council of Canada.

The article focuses on the tradeoff between color rendering accuracy and lamp efficiency to show that high color rendering accuracy is appropriate and, contrary to a common misconception, does not intrinsically require greater electrical energy consumption.
