Albertslund tests if new lighting designs can improve concentration and the ability to learn.
What was the purpose of the project?
To create evidence-based and useful knowledge about how light in classrooms can support a good learning environment and reduce the use of energy.
Chosen solution (brief description of solution, method, process)
Four classrooms were renovated. Two classrooms facing east and two classrooms facing west. In the four classrooms new light was installed, acoustics were improved, and adjustable external shading curtains were placed on the windows facing east. The light can change intensity and colour temperature. Predefined settings were made. Light according to existing regulation (300 lux, 3000 kelvin).
It is up to the teachers to use these three settings to create different moods to support the various learning situations in the classroom. In two classrooms (one facing east and one facing west) there is a timer on each stetting, changing it back to the standard setting after 30 minutes. In the two other classrooms it is up to the teachers how long they use each setting.
Mixed methods were applied. Both an anthropological approach with observations and interviews and a technical approach with measurements of reflectance of materials, noise, daylight level and simulation of direct sun to choose shading solutions.
We measured and observed the existing situation, which resulted in design parameters. A lighting designer interpreted the design parameters into a specific design. The design was applied to the classrooms, and the new situation was evaluated with the same mixed methods.

Measurable effects (what values have been achieved with this solution compared with a “traditional” solution (if any))
The teachers’ use of the lighting scenario was studied through a mixed-method approach, combining qualitative research material from observations and interviews, and quantitative data from the dynamic lighting design. The results show that the teachers used the different scenarios and that they created individual patterns for interaction with lighting as a tool for teaching. The parameters were related both to the time-dependent variation of daylighting conditions referring to seasons, time of the day and orientation of the classroom as well as to different teaching and learning activities in classrooms. Both aspects should be considered when designing interactive lighting systems for learning environments, thus creating an engaging tool for teachers.
Lessons learnt? (i.e. what would you do differently next time, both in process and implementation)
The triple helix collaboration was very successful, since it gave us the possibility to make a real case study and collect a large amount of qualitative and quantitative data. The analysis of this data has been very time consuming and there is still a lot of valuable data to be analysed and used. Next time we would allocate more time for analysis and writing scientific papers.
Date of opening: Spring of 2018

These papers are about the pre-project, stating the criteria of the design based on pre-analysis and a literature review on the topic. The connection of these findings to this paper and final design, methodologies and analysis is clearly stated in a final paper, which is submitted for peer review.
- Sen, S., Schledermann, K. M., Hansen, E. K., Nielsen, Dynamic Light in Class Rooms – a New Way of Teaching 2018. In per review
The unique contribution of this paper is that all the data collected from the final design case study during the previous 6 months, as well as the analysis and findings, are new, so this paper contributes with the absolute main findings of the overall project.
The last data of this project has been collected and analysed in December 2017 and January 2018. The focus of the analysis was the TOCHI special issue, but it was not accepted, so the data was analysed in more depth and the paper was rewritten in May and June 2018 to be submitted in another peer reviewed paper.

The future (Is it possible to scale up? What other areas could benefit from this solution?)
The approach, to study how dynamic lighting can be used as a tool for teachers, will be scaled up in other projects and studied in other kinds of buildings.
