Tunable white lighting in the classroom: The new ROI is ROO

Throughout the past few years, we at LEDs Magazine have seen more solid-state lighting (SSL) product development targeted at educational environments. School officials, especially in the public-school arena, must manage strict budgets and plan strategically to obtain the best return on investment (ROI) possible, so the potential financial implications are important factors — first, the cost of premium equipment and installation, but then balanced against the possible payback due to energy efficiency initiatives and less maintenance. One consideration beyond the established cost reductions of SSL in institutional buildings such as schools is the possible impact of tunable white lighting in the classroom. Naturally, dimmability and other controls features such as granularity of color temperature can be customized to various classroom tasks and increase visual acuity. But what’s becoming even more appealing to educational administrators is the ability to influence less “visible” factors in the classroom, such as mood, behavior, and concentration. Strategies in Light, co-located with The LED Show and Lightspace California, will draw more attention to so-called human-centric lighting applications as this, also known as lighting for health and wellbeing. One such presentation, “Lighting for pupils…Tunable white lighting in the classroom and the new ROI,” by Tricia Foster of Acuity Brands Lighting and Catherine Hollenshead of Estes, McClure & Associates (EMA), will feature a case study on a Texas school district’s first-hand experience using tunable white lighting in several classrooms. Here the speakers give a glimpse into the new classroom experience. They will offer up additional details during SIL on how ROI has evolved into “return on objective” (ROO) in such installations. — Carrie Meadows

Tunable white lighting is the future of classroom lighting because of the positive impacts on mood, behavior, and concentration. In a time when schools are seeking every possible advantage to improve the learning environment, they cannot lose sight of the impact lighting and controls can have on learning. Lighting and controls need to be considered tools that are as critical as smartboards, tablets for students, and all the other modern-day teaching tactics that are being deployed in classrooms across the country.

Acuity Brands and EMA will discuss the installation of the tunable white solution in the Carrollton Farmers Branch Independent School District (ISD) where the ROI went beyond energy — showing what it took to bring the energy manager, the teachers, the parents, principal, and even the students along for the ride. In addition, the results of a Pacific Northwest National Laboratories (PNNL) Gateway Study are now public and we will show the results of this study based on the installation at CFB ISD.

Tunable white lighting and its potential impact on the K–12 learning environment has been the subject of a number of research studies, but not a lot of practical, in-the-classroom experience exists,” Foster points out. “Catherine and I had the opportunity to work with the school administration, teachers, and students to gain insight and feedback on just how effective lighting can be on student behavior and performance.”

“As part of our presentation, we Twill walk through deploying a tunable white system into the classroom,” adds Hollenshead. “We will review the return on investment from energy savings over the previous fluorescent lighting system, but also dig into the multiple benefits to the teachers and impact on students as they experience lighting that can be adjusted to mood, activity, time of day, and other factors.”

Lighting industry ‘must teach schools the value of good lighting’

Lighting professionals must join with educators to improve lighting in schools, Chris Boyce of Capita Symonds told LuxLive.

Better cooperation is needed to make use of government funding for primary and secondary education, Boyce said in a keynote speech.

Boyce urged lighting professionals to use their knowledge and skills to help architects and educators to make the right choices. He said: ‘We need the people who design the lighting in education to help us as architects to change the way light is given in education – that is my plea to you.’

He also called on schools to learn lessons from the way commercial offices and universities are lit.

Boyce warned of the dangers of installing low-energy lighting without understanding how it will be used. The drive by the government to standardise energy-efficiency and school designs could compromise the quality of school lighting due to a lack of evidence on the need for quality lighting, he  warned.

‘It’s my view that lighting will suffer,’ Boyce said, ‘and it’s the industry’s job to work with architects to persuade teachers that they need quality space and not just space.

‘Lighting contributes to educational outcomes. My request for the lighting industry is to challenge the normal education need by gathering the data to back up the need for it.’
