Over the coming year, Rotterdam’s Energy Floors wants to sell smart surfaces for public outdoor spaces that generate data, measuring how many cars, pedestrians and cyclists are passing by. These can be used to regulate traffic flows and lighting, for instance. These Smart Energy Floors also generate energy via the solar cells that are integrated in them. At the moment, the Rotterdam municipality is on the lookout for a suitable location for the application of this kind of energy surface in a city parking lot, says Michel Smit, CEO of Energy Floors. A trial of this is planned for 2020 in cooperation with the Engie energy company.
What motivated you to set up Energy Floors and what problem has this resolved?
“Our first idea was to create a Sustainable Dance Floor on which people can dance to generate energy, something that you can actually see because the tiles light up. (By converting the vertical movement of the dancer on the floor into rotational movement through a mechanism underneath the flexible floor tiles so as to generate energy, ed.) That idea originally came from two companies: Enviu and Döll. In 2017, they brought me in as a hands-on expert from the club scene. I had been running a large nightclub in Rotterdam for four years, called Off-Corso. They wanted to bring sustainability to the attention of young people and thought that the Sustainable Dance Floor could help with that.
Unlike today, it was difficult to get young people interested in sustainable energy at that time. It had a bit of a stuffy image. We initially tried out that first version of that dance floor at the Rotterdam pop stage Watt (which went bankrupt in 2010, ed.) – that made it the first sustainable club in the world. We started building our business around that first Sustainable Dance Floor.”
What has been the biggest obstacle you have had to overcome?
“That we had customers for the Sustainable Dance Floor before we had the actual product. At first, we only had a drawing of the floor, an artist’s impression. We worked out the concept and technology with TU Delft and TU/e in Eindhoven. And together with Daan Roosegaarde, we were able to further develop the interaction between the public and the technology. This is where our Sustainable Dance Floor is unique: the interaction between people and sustainably-generated energy. When they dance harder, they generate more energy.
This is what we want to offer people when it comes to our business proposition. That they themselves have an influence on improving the sustainability of energy. We want commitment. This is what we are specifically focusing on. The second obstacle was how we could go about expanding the scale for things that this product can be used for. So that it has a real impact. That’s why we wanted a surface that was suitable for large permanent fixtures in outdoor areas. We had to drop our initial unique selling point – as in ‘human energy’ – for this type of surface. Instead, we came up with our Smart Energy Floor. We use solar energy rather than kinetic energy. Otherwise, the project would be impossible to complete. The system has to be cost-effective, robust and resistant to wear and tear.”
What has been the biggest breakthrough so far?
“That we sold 25 of those Smart Energy Floors to schools last year. Three of them in Germany and the rest in The Netherlands. As a company, we have three business propositions: the Dancer for clubs and discotheques, for example, the Gamer for schoolyards and the Walker for large outdoor facilities. The first Walker in the Netherlands is located near Croeselaan in Utrecht on a crossing opposite Rabobank’s head office. Rabo has partly financed this floor. There is also one in the palace garden of the President of Malta. He found us via Google. It is a public garden with a Gamer and a Walker. A Gamer costs 13,000 euros including the installation. While a Walker is available from 25,000 euros.
The fact that we appeal to people all over the world doesn’t surprise us at all. Our first signed contract was with the producer of Absolute Vodka. He wanted to make a road show around New York with our dance floor in 2009. So, that’s what we did. We get two to three requests a day. Our challenge is to be able to deal with these properly. Because we want to keep on innovating too. As an example, you could also use the Smart Energy Floor on motorways if you developed the software for that.”
What can we expect from Energy Floors over the coming year?
“We want to start selling more Walkers. This is a new market for us that has a lot of potential. Smart city projects that you can use it in are much larger projects than what we have done so far. You could equip bike paths with our technology so that you can turn them into walkways. We are going to do a smart parking trial next year together with Engie and the municipality of Rotterdam. We will be installing a Walker for that reason. The energy generated by the solar cells in the surface goes to the electricity grid and can subsequently be used to charge cars. Currently, we’re looking around for a suitable location.
We are also planning to enter the German market. This fits in well with our product and company. There is plenty of capital there and focus on sustainability. And the German way of doing business isn’t that different from the Dutch way of doing business.”
What is your ultimate goal?
“Ultimately, we want our Smart Energy Floors to be used in all the world’ s major cities and have their data connected to each other. You can learn a lot from each other’s experiences. You could monitor and influence the behaviour of the users of our surfaces on city roads. For example, in order to regulate busy situations at certain locations. You can apply the technology in a smart way. If there are very few people driving or walking on the road, you could turn the lights off in the evening.”
