The Urban Passive House (Passivhaus)

A quick survey in North America's cities

By Adrien Roux-Delagarde


Even if Europe is the birthplace of Passive Houses, the concept has arrived in America years ago and you can see nice examples of passive houses all around the continent. Some of them even try to fit in the cities, the place where the ecological and sustainable issues are most crucial.


North Park Passive Houses (Victoria, Canada)

The goal in developing this project is to demonstrate that such buildings are not only more comfortable and sustainable, but also economical and achievable right here, right now. The design combines high performance building requirements with contextual issues and sound urban design. »  HCMA

LoneFIR Urban Passive House (Portland,USA)

 
“The efficiency of the LoneFIR Passive House is remarkable: energy costs of $600 per year are anticipated compared to a standard code construction estimated at $3,000 per year. Overall, the LoneFIR Passive House offers a model of sustainable urban living: urban infill development supporting a walkable neighborhood density executed with the dramatic energy-efficiency of the Passivhaus Standard. By combining “location-efficiency” and building efficiency a truly miniature carbon footprint is gracefully achieved with an increase in livability.” Greenhammer.com

But on beautiful spring days when the temperature is mild, the house remains open to the outdoor weather to allow for fresh air and ample ventilation."  Inhabitat.com
