What makes this office different is that it also has hydrogen fuel cells, which store electricity from the turbine. When the wind inevitably drops, the building can still be powered from the stored energy in the fuel cells.
It's one more step on the road to a truly renewable future, and it's one more nail in the coffin of the fossil fuel industry.
With advances in battery design, fuel cell storage, hydro-storage and the North Sea Interconnector, the variations in wind power output will soon be smoothed out and it will be one more argument against wind turbines that will be shown to be scaremongering by vested interests.
As we go into election season, I would expect BBC Scotland to have some discussion programmes as they did during the last Holyrood elections. Unfortunately at that time the debate about future energy was dominated by weary willies from the coal and nuclear industries who would pepper their derisory snorts with the words "base load".
This time, we can show that the base load could so easily come from other sources and the vagaries of the Scottish weather are really nothing too much to worry about.
