While this is not a "Passive House" it does employ passive heating and cooling strategies; south facing skylights provide heat in winter and operable windows with an open floor plan provide passive cooling in summer.
The house also has mechanical ventilation that utilizes a heat recovery ventilator. This guarantees continuous, filtered, fresh air.
The house is completely wrapped in reclaimed rigid foam insulation. This makes the entire structure thermal bridge free.
The heating and cooling is provided by super efficient electric heat pumps. While these are currently grid tied, the high pitched metal roof allows for solar panels at a future date. Then, the heat pumps' energy could come directly from the solar array.
Second story poptop + addition on single story brick ranch house.
Windows take advantage of passive solar heating and cooling.
Raised heal Scissor trusses create super insulted roof system.

Existing single story brick home with full second story, addition and new garage. Currently under construction
New 500 SF ADU located in Portland, OR. Single story with cathedral ceilings and lofted bed space. Currently under construction.
This addition was strongly informed by what was possible within an historical Denver neighborhood. The rear, 2 story contemporary addition allows one large "living room" (kitchen, dining, living). This allows a much better connection to the south facing rear garden area. It also adds 2 bedrooms above.
From the street, the addition is barely noticeable, which was part of the historical addition requirements.
