Summary
Machine-generated summaryThe buyer is procuring the supply and installation of small wind turbines as part of a construction project in Berlin-Mitte. On the site at Leipziger Strasse 2, an extension to the Bundesrat with a visitor centre is being built, comprising a five-storey head building and an L-shaped six-storey administrative wing. The works include three vertical-axis small wind turbines with 1 kW rated power, DC/AC grid connection and remote shutdown. The project aims for BNB certification in Silver, so the contractor must support certification, meet requirements on waste, noise and dust, keep monthly site inspection records and provide FSC or PEFC chain of custody certificates for wood products. Works start December 2026 and finish November 2028.
