Luxembourg National School of Health: A Leader in Sustainable Energy

Energy-Positive Design Combines Renewable Solutions and Efficient Infrastructure

The Luxembourg National School of Health (LTPS), located in Ettelbruck, has become a pioneering example of sustainable energy use, not just within Luxembourg, but across Europe. Since its completion in 2019, the building has been producing more energy than it consumes, thanks to an innovative mix of energy-efficient technologies and sustainable materials. The building’s design prioritizes renewable energy sources such as solar power and integrated heating solutions.

Energy-Positive Building: Solar Panels and Heating System

Photovoltaic Panels, Solar Thermal Collectors, and Energy Storage for Heating

The LTPS building houses 430 students in classrooms and technical rooms, all of which are powered by an array of photovoltaic panels. These solar panels generate twice the amount of electricity needed to run the building, with surplus energy contributing to the overall positive energy balance. An advanced hot water tank, standing 20 meters tall, plays a critical role in the building’s heating system. It stores up to 100,000 liters of water and is heated by solar thermal collectors, which are integrated into the building’s façade, designed to look like windows but serving as energy generators for the tank. This design ensures the building remains energy-efficient and eco-friendly.

Sustainable Building Materials and Low Environmental Impact

Clay Walls, LED Lighting, and Air Renewal Systems

Every detail of the LTPS building has been designed with sustainability in mind. The classrooms and corridors are constructed using white clay, which not only provides insulation but also reduces the building’s environmental footprint. The building uses only LED lighting for energy efficiency, and an advanced air renewal system ensures the indoor air quality is consistently refreshed, promoting a healthy and comfortable environment. These materials and technologies contribute to the building’s low environmental impact while maintaining high energy efficiency.

A Comfortable and Productive Learning Environment

Enhanced Educational Opportunities and Student Comfort

Beyond sustainability, the LTPS building also prioritizes the well-being of its occupants. Deputy director Carlo Gudenburg highlights that the classrooms offer a pleasant atmosphere in terms of temperature, humidity, and acoustics. The building is designed to create a conducive learning environment, encouraging students to engage actively. The combination of energy-efficient systems and comfortable design ensures the building remains a state-of-the-art educational facility.

Project Funding and Long-Term Impact

29 Million Euro Investment and European Union Support

The total cost of the LTPS project is 29 million euros, with the majority of funding provided by Luxembourg’s government, and a smaller portion funded by the European Union’s Cohesion Policy. The building serves as a model for future educational and public buildings in Europe, demonstrating the potential for creating energy-positive structures that also foster sustainability in daily operations.
