For the „Energiebunker Hamburg“ Project, SOKRATHERM was awarded with the „Deutscher TGA Award 2014“ (German award for building technologies) which was granted for the first time during the „Berliner Energietage“in May 2014.
The award initiated by the „Moderne Gebäudetechnik“ (Modern building technology) magazine assigns outstanding planning performance as well as innovative products and systems by the furnishing industry. Focus criterion of the jury was sustainability, the reduction of the primary energy consumption and the preservation of ressources. Innovative solutions in the goal triangle of ecologically, economically and technically sound realization were searched and found.
Regarding these aspects, the Energiebunker is an excellent example for the category modernization. Here, an innovative and efficient energy concept was designed and realized in which renewable heat and power are produced from a biogas powered CHP unit, thermal solar collectors (on top of the Energiebunker) and photovoltaics (on the southern facade). The heat is stored in a huge 2.000 m² buffer storage and distributed to the sourrounding buildings, the power is fed into the Hamburg mains.
Core of the project is the compact CHP unit GG 530. It is the world’s most compact CHP unit of the 500 kW class: In contrast to conventional CHP units of this power class which have to be mounted laboriously on site, this CHP unit is delivered ready to connect in a sound absorbing case and can be commissioned within days. Its total efficiency of over 90 % (40 % electrical, 50 % thermal) is outstanding.
The impulse for the seminal project of turning a rotten nazi building into a peaceful renewable powerhouse came from IBA Hamburg and the public power company Hamburg Energie. The planning was done by Averdung engineers in close cooperation with SOKRATHERM. The award ceremony presentation (in German) can be downloaded here.
