IES LD+A Research Matters: Next Generation Healthcare Lighting

08/01/2016

Three key elements of emerging healthcare lighting design are circadian wellness, dark adaption, and a high-fidelity visual environment for patient care. Solid-state lighting solutions with spectral control capabilities can be seamlessly integrated into healthcare lighting designs using advanced controls and sensor geometry to create a patient-friendly experience. For patients who need to sleep during the day, these technologies can be manually enacted, along with appropriate window shading, to create a nighttime environment at any hour.

Lighting Appliance Efficiency Regulations: What's New in the Title 20 Code?
04/13/2016

The California Energy Commission adopted new standards updating the 2015 Appliance Efficiency Regulations (Title 20) for lighting appliances. Updates will roll out in two tiers with Tier 1 effective January 1, 2018 and Tier 2 effective July 1, 2019. Notably, this update adds standards for small-diameter directional lamps. The updated regulations incorporate elements of lighting product quality for both general service LED lamps and small-diameter directional lamps in addition to the traditional lighting appliance efficiency standards previously included in the regulations.

IES LD+A Research Matters: Short-term Color Preference Comparisons are Inadequate for Optimizing Long-term Illumination

04/01/2016

The evaluation of the color rendering performance of electric lighting sources has become a controversial issue, especially in California, where high color fidelity requirements were recently unanimously approved by the California Energy Commission for the next version of energy efficiency requirements for new buildings and major retrofits (Title 24) and light sources (Title 20).  Opponents of the new version of the California energy codes have claimed that the new requirements will result in increased energy consumption and higher cost.  Further, they have claimed that color fidelity metri

California's new residential Building Energy Efficiency Standards take effect on January 1, 2017. The 2016 Standards focus on several key areas to improve the energy efficiency of newly constructed buildings, additions and alterations to existing buildings. The most significant efficiency improvements address attics, walls, water heating and lighting. The California Energy Commission estimates that the 2016 standards will deliver approximately 281 gigawatt-hours of electricity savings annually and reduce statewide greenhouse gas emissions by 160,000 metric tons.
