REA systems combine home-energy monitoring features with automated appliance management and control of distributed energy resources (DER) such as electric vehicle (EV) chargers, rooftop solar panels, and stationary battery energy storage (BES).
Outcome-based energy codes are relatively new. They incorporate strategies that quantify a building’s actual energy performance over time to demonstrate code compliance. The term "outcome-based" refers to the fact that compliance is linked with a building’s actual energy “outcome” which may be measured post-occupancy.
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.
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.
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.
Popular Science—Popular Science highlights health damages of the light we have been using for the past 100 years and new plans of improvement. Professor Michael Siminovitch shares his insights. This article was originally published in the January/February 2016 issue of Popular Science.
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.
