Time for action on French roofs. We recently talked to you about the interesting project of an installed greenhouse on top of a building (great results after the first 60 days). Today the reports of a new electricity generation plant arrive: a sort of magic box called WindBox.
WindBox: double action and less waste
The initiative is part of a strategic plan to reduce CO2 emissions in the city of Rouen, France. The first WindBox modules were installed on a 10-storey building housing 84 apartments. It is the first building in the whole country to benefit from this mixed equipment.
On 24 May, eight WindBoxes, each weighing 350 kg, were positioned on the edge of the western facade of the building.
How it's done?
In a nutshell: each Windbox is composed of a horizontal turbine placed in a large "box" on which the solar panels are placed. In the form factor it has something of Aeromine, a project of which I talked about in this post, but it is more practical.
The plant produces the energy equivalent to 9,4 m² of photovoltaic panels. The even more interesting aspect is that each of the modules generates only 24 g of CO2 during its life: to be clear, the average of the solar panels is about 43,9 g.
What can the "magic box" do?
Over a 20-year period, the eight WindBoxes installed in Rouen are expected to provide around 14 megawatts of electricity per year. Since this energy is not stored, it will be fed directly into the building's electricity grid. "This mixed energy system will allow us to have double energy production: one part will be used to power the common areas, including the two elevators. The excess will be fed into the grid," says Paul Bernstein, operations manager for this project.
The cost of the systems is quite affordable: around 4.000 euros / module. It would be very nice if many buildings could cut costs and emissions with similar systems, do you think?
