General Energy Use, Strategies and Systems

Energy Strategies:

The home uses Passivhaus design practices to minimize infiltration with tight envelope and an ERV. A ground source heat pump is used for conditioning the air both heating and cooling as well as domestic water heating. Photo voltaic panels cover the three southern facing roofs sections and provide a standard power of 10 kW.
