LG MUL TI V WATER Solution with Geothermal Application
Bouygues Challenger
The industrial group Bouygues was established in France in 1952. It now maintains operations in 80 countries and employs more than 131,000 people. In 1988, after two years of construction, the new headquarters for Bouygues Construction was officially opened for business. Named Challenger , the
complex became a technological showcase for late 20th
century architecture.
Site Information
Bouygues decided to convert their headquarters into an eco-friendly building by significantly reducing its energy footprint. The LG MUL TI V Water system was chosen as the ideal HVAC solution for this project. The system not only saves energy but also reduces water usage as it recycles water in order to regulate the temperature of the building. With LG’s advanced technology, the building’s water consumption was reduced by more than 70 percent.
