What is a Passive House?

German: (Passivhaus)

The energy efficiency in a building, which reduces the building’s ecological footprint.  The focal point of a Passive House is to minimize air leakage from the property.

How is this accomplished?

Passive houses are designed with super-insulation, high-performance windows, an airtight envelope that minimizes energy consumption while providing thermal comfort to its residents.
