A primary school in Leipzig, Germany trial TRILUX Opendo LED with CO2 sensor

The Clara Schumann primary school in Leipzig, Germany, is a state-recognised private school with a holistic approach to education and a creative focus centred on music and the arts. The school was looking for a partner to refurbish its outdated T8 lighting solution in a total of 150 classrooms.

As a first step, a trial of the TRILUX Opendo LED was undertaken in one classroom featuring an integrated CO₂ sensor for monitoring air quality.

Goals for the lighting renovation

The T8 fluorescent tubes installed in the school no longer met the light quality and energy efficiency requirements. In addition, the luminaires are directly affected by the upcoming T8 lamp ban, so there was an acute need for action. The school sought a solution that would reduce energy costs and, with its light quality and luminaire design, match its high standards and artistic orientation.

 The solution

Stephan Weise, Head of Sales East at TRILUX Germany, explains, “With OPENDO LED, we have a system in our portfolio that optimally meets the requirements of schools and educational institutions. This includes special light distributions such as asymmetrical panel light and flexible mounting options. Opendo LED can be installed as a single luminaire or continuous row, as a surface-mounted variant, or as a suspended luminaire, so it is perfectly adaptable to the challenging school architecture. The quality of light can also be precisely matched to the respective lighting task, for example, with UGR19 for working with tablets and on computers. Another important “soft factor” is the modern design with the lateral light edge, which makes Opendo LED pleasantly different from the “classic functional” luminaires and ensured a modern lighting and learning atmosphere.”

Three-stage traffic light system

The integrated CO₂ sensor technology offers the school an additional practical benefit that makes many things easier, especially in times of a pandemic. The sensor continuously measures the CO₂ concentration in the room and indicates the air quality via a three-stage traffic light mechanism. If the LED light switches from green to red, it is time to ventilate. This offers teachers and children a safer working and learning environment and introduces students to the topic of air quality.

Next steps: how smart will Clara Schumann primary school become?

Hardly any lighting management is implemented in the Leipzig primary school. However, networked Opendo LED solutions with daylight and presence sensors are used in similar school projects. Sensor control reduces energy consumption and increases the quality of light by ensuring a permanently uniform lighting level.

Stephan comments, “We once again show the customer the possibilities and potential of smart lighting using various references and calculations. Customers are often surprised by how good lighting management can achieve and how easy it is to implement. The Opendo LED is networked with the LIVELINK LIGHT MANAGEMENT SYSTEM in a flash, wirelessly via Wi-Fi if desired. It is also available as a variant with integrated PRESENCE AND DAYLIGHT SENSORS. Smart school lighting can be so simple.”
