Today, WIND-projekt received the Association of Freelance Architects Mecklenburg-Vorpommern in Grapzow. The topics renewable energies and energy storage have grown in importance also in the construction sector. The architects seized the opportunity to inspect the energy storage facility as well as one of the E-126 wind turbines with a power of 7,000 kW. Residential and commercial buildings are more and more equipped with energy supply facilities with photovoltaic being the leading technology in this sector. In the view of this, the architects were especially interested in possibilities for the storage of fluctuating renewable energies and for the recuperation of electrical energy and heat from the storage.
