In the ongoing quest for sustainable innovation, anergy is emerging as a revolutionary energy solution, offering a cleaner and more efficient future. Join us as we explore the foundations of anergy and discover how it is transforming our energy approach to create resilient, environmentally responsible communities.

What is Anergy? Anergy goes beyond conventional solutions by establishing a bidirectional energy exchange loop. This innovative concept is based on geothermal boreholes that feed a smart network, connecting buildings to efficiently distribute heating, cooling and even electricity.
An Innovative Joint Venture in Luxembourg: CALLISTO S.A. This bold vision is brought to life by the joint venture CALLISTO S.A. Born from the collaboration between IKO Real Estate, LuxEnergie and Encevo in Luxembourg. This alliance aims to develop the country’s first anergy network, offering a new and sustainable approach to energy.
How Does Anergy Work in Everyday Life? In winter, geothermal probes capture heat from the ground to warm the buildings, while in summer, they absorb excess heat to provide passive cooling. This smart principle, based on more than 300 geothermal boreholes, ensures an energy response tailored to the seasons.
Environmental Impact and Carbon Footprint Reduction : Anergy is not simply a technical breakthrough, but an environmental revolution. By covering 100% of the heating and cooling needs of the Rout Lëns district, for example, through geothermal heat pumps, the network makes a significant contribution to reducing the carbon footprint. In addition, half of the required electricity is generated by local photovoltaic panels.
Statements from Key Stakeholders : Sandra Huber, Group Chief Development Officer at IKO Real Estate, emphasises that the project embodies the company’s commitment to a sustainable future. Emmanuel La Fonta, Group Chief Financial Officer at IKO Real Estate, expresses his pride in offering a competitive, high-quality, reliable and sustainable energy resource.
