Profiles in Solar – Japan's First Solar Office Building

Back to Blog |

To start the new year off, we here at PosiGen are going to be featuring a different piece about solar each week. It could be a person, location, or event.

Monday, February 26th saw the opening of Japan’s first ever solar powered office building in Saga. The building houses the Saga branch of Daiwa House Industry Co., a construction company that created as an example of their work in sustainable construction.

The solar panels housed upon the roof of the building produce the electricity for the building that is stored within lithium-ion batteries. The electricity produced by the panels is enough to power the entire building during the day, and that stored in the batteries powers it through the night.

The efforts to create an environmentally friendly building also include well water and a solar air conditioning system. The construction is an exciting look into the possible future of  environmentally conscious efforts in the creation of new office spaces.
