Deutscher TGA Award 2014

Energiebunker innen GG 530 mit Wärmespeicher DTGA Award 800x1300For its CHP project „Energiebunker“ (energy bunker) Hamburg-Wilhelmsburg, SOKRATHERM was awarded with the „Deutscher TGA-Award“ (German building technologies award) which was granted for the first time during the „Berliner Energietage 2014“

The award initiated by the magazine „Moderne Gebäudetechnik“ (modern building technology) awards outstanding planning achievement as well as innovative products and systems of the supply industry. Special emphasis was aimed at sustainability as well as reduction of the primary energy consumption and protection of ressources. Innovative solutions in the target triangle of ecology, economy and technology were awarded.

Considering these aspects, the project energy bunker, in which a deteriorated World War II bunker was transformed into a renewable energies power plant and memorial, excelled in the category modernisation. Here an efficient energy concept was designed and implemented in which heat and power from renewable gas cogeneration, photovoltaics and solar collectors are produced. The heat is stored in a 2.000 m³ buffer storage and distributed to the surrounding buildings, the power is fed into the Hamburg power network.

A central element of the project is the compact CHP unit GG 530. It is the world’s most compact CHP unit of the 500 kW class which, in contrast to conventional CHP units of this size which need to be laboriously built on site, is delivered fully mounted in a sound absorbing case and can be commissioned within days. Its total (over 90 %) and electric (40 %) efficiency is outstanding.

The impulse for the EU funded project was the IBA Hamburg and it is operated by the municipal power company Hamburg Energie. The total planning was performed by the engineering office Averdung in collaboration with SOKRATHERM.
