Green Energy

Commissioned to create a family residence in an area known for its cold, snowy winters and hot summers, Florian Busch Architects has completed the House W. Taking the form of a timber barn-inspired structure that's partially covered in solar panels, the home's energy efficient design allows it to harness almost twice as much power as it requires annually.

House W is located in Nakafurano, Hokkaido, Japan. The home is situated on the site of an old farmer's barn and is surrounded rice paddies and asparagus fields, so draws inspiration from this setting.

The exterior is part-finished in a solar skin that allows it to run off-the-grid (together with a battery array). A studio representative told us that there are 56 panels installed, resulting in a total capacity of 23 kW. This is combined with a heat pump that's connected to a nearby water source and offers a relatively constant temperature throughout the year, allowing it to run the underfloor heating as well as producing warm water for the house.

We've no figures on the home's actual power usage, but Florian Busch Architects says the solar panels provide almost twice as much as its requirements, annually.
