Generally, people expect two light sources with the same rated color appearance to appear identical when installed in their homes and businesses. Obvious variation often leads to dissatisfaction, complaints and product returns. To avoid these issues, it is important that light sources have sufficient chromatic consistency to ensure color matching for most people. Currently, the lighting industry relies on binning for correlated color temperature (CCT) and Duv to address this issue.
The California Lighting Technology Center and the California Energy Commission hosted a webinar focused on research outcomes from our recent EPIC-sponsored project, A New Generation of LED Lighting Systems!
The webinar focused on four key research outcomes:
Lighting design projects often include multiple design constraints. For example, a lighting design should meet target light levels, limit glare and provide appropriate color fidelity while not exceeding the power or energy budget defined for the project. For select projects, circadian considerations have recently been added to the design criteria list. Circadian lighting is defined as lighting that influences a non-visual, physiological response within the human body.
This presentation includes best practices in residential lighting design to comply with California's 2016/2019 Title 24, Part 6 Building Energy Efficiency Standards.
This presentation includes best practices in nonresidential lighting design to comply with California's 2016/2019 Title 24, Part 6 Building Energy Efficiency Standards, with specific examples included for office lighting projects.
California's new residential Building Energy Efficiency Standards take effect on January 1, 2020. The 2019 Energy Standards focus on several key areas to improve the energy efficiency of newly constructed buildings, additions and alterations to existing buildings.
California's new nonresidential Building Energy Efficiency Standards take effect on January 1, 2020. The 2019 Energy Standards focus on several key areas to improve the energy efficiency of newly constructed buildings, additions and alterations to existing buildings. Significant changes in the 2019 Energy Standards address ventilation, HVAC, demand response and lighting. Notably, the 2019 Energy Standards now include requirements for healthcare facilities, although there are many exceptions for this building type.
This year, California demonstrated leadership as the first state in the country to set appliance efficiency regulations for general service lamps that ensure both lighting quality and efficiency. To build on this leadership and accelerate the adoption of the high-quality, energy efficient LED lamps, in July 2018 the University of California launched a new procurement program known as The Million LED Challenge. The program supports the UC Office of the President’s Carbon Neutrality Initiative, which commits the UC to emitting net zero greenhouse gases from its buildings and vehicle fleet b
