This document describes the core principles and ambitions behind building an energy efficient passive house, including extreme energy efficiency, minimal footprint, site integration, healthy interiors, durable construction, and attention to detail. It notes that a passive house certification is a rigorous voluntary standard focusing on high energy efficiency and quality of life at low operating costs.

Let’s talk more about details of Passive House Design.
A house build to current energy code in Minnesota could potentially qualify as a Passive House in California.
Passive House Standard performance requirements are always the same, regardless of building location
Climate zone and a building’s distinctive location impact the design significantly
Therefore, Passive House buildings will look differently depending on where they are located
The standard is not exclusive to residential construction. Passive House design is NOT an add-on or supplement to architectural design, but an integrated design process with the architectural design.[3] Although it is mostly applied to new buildings, it has also been used for retrofits. Best building energy standard in the world today.
Passive House with “passive” systems and small post-heater uses a max. of 4,750 British thermal units per square foot and year for heating
Conventional Building with “active” heating system uses 5–30x more heating energy than a Passive House
