Viessmann develops seamless climate and energy solutions that provide the environment with the optimum room temperature, hot water, electricity, and good air quality in equal measure. In an integrated range of solutions, they seamlessly connect products and systems based on the right energy sources via platforms and digital services.
In order to supply the entire airport complex with heating and cooling energy, a central energy system was built for the Jože Pučnik Airport. The construction of the corresponding energy infrastructure (electricity, water and gas supply, heating, cooling) was also carried out as part of the project.

The system is currently used to supply heat to the facilities in the airport complex, while also providing space for the installation of refrigeration room equipment that will be installed in the future. New Viessman gas boilers have been installed for the heat supply. Most of the heat demand is covered by special Vitocrossal 200 condensing boilers, which also use the condensing heat from flue gases. This technology increases fuel efficiency while reducing emissions. The peak heat demand is covered by a special Vitoplex 200 low-temperature boiler, which is only switched on in extreme weather conditions and therefore has a small share in the total heat production. The heat generation is managed by a controller that cascades the boilers. The heat is mainly generated by the condensing boiler. As a result, it is more energy efficient (lower fuel consumption), environmentally friendly (fewer harmful emissions) and more economical (lower operating costs) to operate.

About the Energy Efficiency Awards

The Energy Efficiency Awards in Slovenia were organized by the German – Slovene Chamber of Industry and Commerce (AHK Slovenia) in April 2021. The AHK Slovenia has invited German companies that have successfully implemented innovative energy-efficient technologies in Slovene buildings to submit their most promising reference projects. Through a competitive selection process by our expert jury, six German companies have been chosen to receive one of the desired awards and present their building solutions to a broad range of experts, decision makers and media representatives.

The Energy Efficiency Awards in Slovenia is funded within the German Energy Solutions program of the Federal Ministry for Economic Affairs and Energy. Its aim is to recognize outstanding achievements of German technology suppliers in Slovenia, showcasing technologies and innovations that contribute to increasing energy efficiency in Slovene buildings. It is designed to help German companies strengthen their position in the Slovene market and make new connections within the sustainable energy and building sector. The awards provide participating German companies the chance to showcase their technologies and services that focus on increasing overall building performances.

The program of the online-event included discussion by industry experts on energy efficiency in Slovene buildings, the video presentation of the six final projects, the award ceremony and a final digital networking event, giving you the opportunity to exchange ideas and explore business opportunities with industry pioneers and experts.

The Energy Efficiency Awards are part of the German Energy Solutions Initiative of the German Ministry for Economic Affairs and Energy to recognise the positive impact German energy efficiency technologies have on Slovenia's efforts to become more energy efficient.
