Passive Tiny House Community

Chicago, Illinois

The Flat-Pack Passive House was developed in partnership with Passive to Positive as a flexible, high-performance tiny house built from a special modular construction system.  The system together with the application of energy-saving strategies and passive design principles reduces annual energy demand by as much as 70%.  The complete approach incorporates all-natural materials, no embodied toxicity, almost zero embodied energy and virtually zero GWP.

In contrast to the typical tiny house built on a trailer chassis, the Flat-Pack Passive House is quickly assembled on site using a versatile panel system.  The panels, built of plywood sheathing and internal ribs, are fully load bearing, useable for walls, roofs or floors.  The lightweight panels can be erected easily on site with low-skilled labor and basic tools.  As a simple unit, it can be cost-effectively mass produced and shipped flat-packed anywhere.  It also allows structures to be re-configured, expanded, dismantled or reused, giving ultimate flexibility for tiny houses to evolve and grow to meet changing demands.

 

The panel is also super-insulated, filled with green fiber cellulose insulation.  With high-performance windows and doors the envelope is air-tight and continuously insulated.  The result is an interior that can be warm and comfortable for days without mechanical heating.  Comfort level is enhanced with operable windows providing cross ventilation and a continuous balance energy recovery ventilator for maximum comfort and improved indoor air quality.  The demand reduction is also supported by solar gain and shading control canopies that can be tuned and balanced to deliver comfort in all seasons.

 

These passive design properties enable the house to operate with significantly less power and be fully supported by rooftop solar energy.  With integrated battery storage, all appliances, heat pump, and LED lighting are powered on 12v DC power, thus avoiding solar power loss through typical DC to AC conversion.  For convenience a DC-AC power inverter and line power from the grid are provided as backup, but are not needed for routine operation.
