The challenge
The multi-functional purpose of the arena complex requires multi-functional solutions. The arena space frequently needs to be transformed to fit large and small concerts as well as a wide variety of sports events and competitions:
• Ice hockey
• Figure skating
• Basketball
• Martial arts
This versatility poses a tremendous challenge for heating and water distribution systems: different sports require completely different thermal environments.
The most important requirement was therefore the venue’s rapid, easy and safe adaptability to a broad range of events. This requires modern, high-performing systems that are able to fulfill complex demands while still remaining reliable and energy efficient.
The solution
Uponor floor heating and water distribution systems were chosen due to Uponor’s extensive experience with sports venues as well as the unique flexibility that Uponor pipes and systems offer.
All in all 31 km of Uponor piping were installed:
• 18 km ice-rink piping
• 10 km underfloor heating piping
• 3 km ground energy piping
For maximum flexibility the same pipes that heat the courts also maintain the required temperature when this surface is used for ice-hockey games or figure skating competitions. The use of a thermal primer protects floor structures against the possibility of deformation.
In 2015 the Žalgirio Arena became the first BREEAM certified sports arena in the world. BREEAM is an international environmental assessment method used to evaluate the sustainability of building projects throughout their life cycle. Uponor systems have proudly contributed to the energy efficiency and enhanced value of the arena.
