Canteen lighting for reduced foodwaste

Reducing food waste in school canteens by creating a welcome and attractive eating environment.

The purpose of the project

To find a new working process that helps us to create a more pleasant eating environment for the children – a new way of thinking that can be reused in other reconstructions or new buildings.

Chosen solution

To create a pleasant eating environment for the children, which we hope can reduce food waste since the children will want to stay in the cafeteria and finish their meals, we decided to work with a light designer in a planned rebuilding of the cafeteria. We wanted to install a new and innovative lighting solution that would create a more pleasant environment with less noise and reduced food waste as a result. We also decided to involve a lighting company to get the market’s view and knowledge into our demo. We arranged a company pitch event where light designers could present their ideas, and after this we decided to work with Lightscapes. Lightscapes was hoping to contribute with for example some thinking outside the box, knowledge about what is good light for people, design and planning for a beautiful solution, developing concepts to create a good flow and a nice ambience.

When we had decided on our partners – Lightscapes and Zumtobel – we formed a task group consisting of representatives from the two companies, the project manager for our demo, the project manager for the rebuilding, the project’s architect, electrical consultant, representatives from the school and from the department in charge of school meals. Together we formed a common baseline by participating in study visits and learning more about lighting from the light designer. After that we had several working meetings between which the light designer worked on the light plan and presented drafts. Eventually the plan could be decided and the procurement phase and then the building and installation phases followed. The light designer presented the project and the light plan to the contracted building company, to make sure they followed the plan minutely. The light designer will also return to program the lighting.

The formation of the task group with all its competences was crucial. For example the practical conditions were given by the electrical consultant and the close collaboration with the architect ensured enough daylight, good sight-lines and a harmony between light, colours and materials.

Parallel with the creation of the light plan, a plan for evaluation was formed. The following parameters have been measured in the old cafeteria and will be measured again, both with only a basic lighting in the new cafeteria and with all the features lit:

–                         The children’s perception of the light
–                         Food waste
–                         The number of eating children
–                         The comfort/well-being of the children, related to the cafeteria
–                         Installed effect
–                         Light level

Measurable effects

The goal was to measure reduced food waste, lower noise levels, increased comfort/well-being, a more positive perception of the light, lower installed effect and an increased number of children wanting to eat in the cafeteria. You can read the final results here (in Swedish).

Lessons learnt?

– Involving the light designer even earlier in the process
– Making room for delays in the building process within the time schedule
– The members of the working group were all very important
– It was a good idea to make a quality measure of the slot lights

The future

Lund municipality will build and refurbish several cafeterias, where the experiences from this project can be used. It could also be used by, for example, other municipalities and real estate owners building cafeterias.
