Rainbow Passive Duplex

Rainbow Passive House Duplex, Whistler

1st BC Passive House Residence

It´s a green story by Marken Projects.

1st residential Passive house certified by the Passive House Institute Germany.

After the overwhelming success of the Austrian Olympic Passive House it was just a matter of time until the next Passive House project in Whistler is taking shape. And it is an exciting one: A prefabricated Passive House Duplex dwelling focusing on affordability and on using as many local, renewable and recycled materials as possible.
While most of the components for the Austrian Passive House were imported from Austria, it is important for the development team and client to make this project as „Canadian“ as possible.
