Did you know that Waldsee is home to the first passive house in North America? A Passivhaus is a house that has reached a rigorous standard for energy efficiency, reducing its overall ecological footprint. In 2006 Waldsee celebrated the opening of the Biohaus, a building that uses 85% less energy than a house built to the Minnesota Energy Code. The Biohaus is not only a building used to house villagers during the summer, but is also a space for all sorts of science experiments and STEM learning.
So why are we saying bring on the sun? Because the Biohaus uses solar energy! All of the water used in the Biohaus is heated by solar panels, or Solarpaneele. Low-growing plants make up the building’s green roof, reducing rainwater runoff and adding another layer of insulation to the building. Part of the Biohaus is tucked into the slope of the hill, enabling natural insulation based on the soil. The Biohaus also has huge windows, allowing for the sun to pour in and warm the space. So here at Waldsee we say lass die Sonne scheinen – let the sun shine!
