What is this new PassiveHouse concept?
1970's "Passive Solar" met 1990's "Advanced Building Science" in Darmstadt Germany...


The most comfort &
the least amount of energy needed.  


Quite simply it's the most stringent and highest certified building performance standard in the World. The Passive House designation combines time-honored design principles with advanced performance standards.  


Components of a Passive House:

Sometimes, a new design is so innovative that it completely obliterates all we know about the original object…  PassiveHouse is a totally new science-based enhancement of our passive solar homes of the ’70s…


  • Superinsulation

  • airtight envelope

  • energy recovery ventilation

  • no thermal bridging

  • advanced frames with triple-pane windows

  • maximized passive solar

  • “itty bitty" heat & air units


Built using a true systems approach:

  • proper siteing to take full advantage of passive solar gains

  • super-tight construction

  • eliminating thermal bridging

  • adding super-insulation and leading-edge windows and doors

Laundry Hanging

High Indoor Air Quality

You’ll breathe better every day. The home’s stale indoor air is replaced with clean fresh oxygenated air every 2 hours.


Comfortable, Consistent Indoor Temperatures

Irritating drafts and hot/cold spots are eliminated thru the super tight construction and the absence of thermal bridging.


Operational Savings

Utility bills – really small. 90% less than standard homes.

Maintenance – tight building envelope reduces typical associated costs. Conventional mechanical systems – eliminated. 

 Illustrated Forest Background


Globally, more than 500,000
buildings have been constructed using Passive House principles. In fact, many European countries have already

or are in the process of making it

their standard building code.
