One of the key elements of Passivhaus design has been the use of generous south-facing glazing for passive solar gain. That's great in winter, but you can have too much of a good thing in summer. Some designers install trellises and bris de soleil to cut the summer sun, but Karawitz Architecture goes a step further with an exterior skin of bamboo screens, that can be opened and closed to adjust the amount of solar gain. They gorgeous, too.
When closed, the building takes on the iconic form of the local barns. Designboom adds:
Photovoltaic panels on the roof round off the program, producing 2695 kwh/yr in energy. The foundation slab is the only concrete element, the entire structure is created from the assembly of large solid wood panels, which have been prefabricated in a workshop.

The walls appear to be made from prefabricated laminated wood, perhaps the Holz solid walls made from sustainably harvested wood.
