BUILDING & MATERIALS

Concordia Language Villages believes that architects, engineers, contractors and our staff are responsible for creating the most educationally inspiring, efficient and cost-effective building possible. Through its BioHaus project, Concordia Language Villages is committed to:
  • Reducing life cycle costs
  • Enhancing occupancy comfort
  • Improving learning environments
  • Extending life expectancy of each building
  • Keeping it simple to maintain
  • Reducing environmental impacts
So exactly how does Waldsee BioHaus improve the quality of life inside the building while using 85% less energy than comparable U.S. structures? Good question.
