DOE: Why Tunable? A Look at Schools Using Tunable Lighting

William Attardi on June 27, 2025

LED technology enables dynamic lighting solutions that can adapt to the occupants, tasks, and daylight in a space. Tunable lighting systems can alter the intensity and/or spectral characteristics (color) of the source. As more schools across the U.S. transition from fluorescent to LED technology, many are likely to consider tunable lighting. This case study aims to help decision-makers by looking at past and current tunable lighting projects.

    • Why did schools choose tunable lighting?
    • What features were selected?
    • How was tunable lighting implemented?
    • What was the teacher feedback?

This case study examines tunable lighting installations at eight school districts across the United States. Why Tunable? A Look at Schools Using Tunable Lighting

 

The Lagging Transition to LEDs in Schools — Part 3 by Jessica Kelly, Andrea Wilkerson, Dan Blitzer

William Attardi on January 21, 2025

Parts 1 and 2 of this series discussed the sluggish adoption of LED technology in schools and the dim prospects for fluorescent lighting. This final part addresses the LED choices school facility personnel are considering and the new tradeoffs they face. Based on PNNL’s conversations with schools, the change to LEDs is underway. Upgrading lighting can reduce energy consumption and operating costs and refresh the look and feel of the school. Fluorescent lighting has served schools for a long time. What does maintaining an LED system look like for the next 30 or 40 years? While TLEDs seem like an easy solution today, relying on fluorescent luminaires and other components will become more challenging in the future. Compare the up front and ongoing costs for each LED option and consider developing a “standard” lighting solution that can be repeated over time, space by space, or school by school.

Interesting: The Three Pillars of Independence of an Organization

The 3 Pillars of Independence most commonly refers to a framework from the UK voluntary sector (specifically promoted by organizations like Bond and the Directory of Social Change). It is a toolkit for assessing and maintaining the independence of charities, NGOs, or civil society organizations.

The Three Pillars are:

  1. Independent of Party Politics – The organization (or regulator) must remain free from bias or influence by any political party or the government of the day. Decisions should be impartial, not favoring one political side.
  2. Independent of Populism – It should not be swayed by popular public opinion, media-driven campaigns, or transient public pressure, especially on controversial or unpopular causes.
  3. Independent of the Press – Freedom from media influence or pressure, ensuring decisions are based on evidence and law rather than headlines or public narratives.

This toolkit was created to monitor potential political encroachment on charitable regulation and to ensure charities can operate without undue external interference.
