这是由德国能源及公共设施公司Hamburg Energie联手IBA Hamburg合作的项目，将原纳粹防空地堡改造成绿色能源发电站，位于汉堡威廉斯堡。这是世界第一个这样的项目。该发电站现已经开始向当地居民提供能源，半年前已对游客开放，成为当地旅游一大亮点。

这座高达42米的地堡始建于1943年，当时它主要为当地的人民提供防空庇护站。该改造项目花费为2670万欧元，由欧洲区域发展基金和汉堡天气保护观念组织共同出资。

这个绿色能源发电站不仅能生产清洁能源，还能展现如利用当地资源制造和储存热能。在观景平台还设有展览区和咖啡厅，成为一个有吸引力的旅游景点。

在该项目的结构中心是一个可容纳两百万公升的水库，它既是绿色能源发电站的大型热能缓冲区，又是Reiherstieg地区的供热管网中心。经由生物热电厂、木材燃烧、屋顶太阳能系统以及周边工厂的废热为水库供热，再重新分配给小区周边的建筑。

This concrete Second World War bunker in Hamburg has been converted into a renewable energy plant and visitor centre by urban development company IBA Hamburg (+ slideshow).

From a war memorial to a green power plant: the Energy Bunker in Hamburg-Wilhelmsburg, created by HAMBURG ENERGIE and the International Building Exhibition IBA Hamburg, is the first project of its kind in the world. For exactly a year the Energy Bunker has been supplying heat energy to the residential buildings in the surrounding area. Six months ago it opened to visitors and has become a major attraction. The development of this remarkable joint project is now complete and is being celebrated with an opening ceremony and the unveiling of two plaques.

"Today we are here to mark a project that encapsulates the philosophy of the IBA Hamburg more than any other," said IBA director Uli Hellweg. "After standing empty for more than sixty years, followed by a seven-year project development and construction phase, this war monument has been transformed into a sign of the dawn of a climate-friendly future. Not only does it produce clean energy to supply the district, but also demonstrates how local resources can be used to produce and store heat. With its viewing platform, permanent exhibition, and café, the Energy Bunker also makes an appealing visitor attraction. Almost 100,000 people have visited the Energy Bunker so far."

Dr Michael Beckereit, director of Hamburg Energie, said, "The Energy Bunker has been supplying heat energy since October 2012, and since March 2013 it has also been providing electricity. Its performance and network are gradually being extended. By the final stage of expansion we will be supplying 3,000 households with heat from the Bunker and generating over 2.5 million kilowatt-hours of electricity."

At the heart of the project is a two-million-litre water reservoir that acts as a large heat buffer inside the Energy Bunker, and serves as the centre of a local heating network for the Reiherstieg district. The reservoir is fed by the heat from a biomass thermal power plant and a wood burning unit, as well as a solar thermal system on the roof. This is supplemented by the waste heat from a nearby industrial plant. By bringing these different sources of energy together in an effective way, the Energy Bunker is able to supply the adjacent Global Neighbourhood with heat, and in future will be capable of providing heat to most of the Reiherstieg district. At the same time it feeds into the public grid green electricity from the thermal power station and the photovoltaic unit fitted to the south façade.

The 42-metre-high flak bunker on Neuhöfer Strasse was built during World War II. After the end of the war this concrete behemoth could not be blown up without endangering nearby tenements, so the British Army restricted itself to destroying the interior. On the outside, however, the bunker remained more or less intact. From then on, the ruin stood in the middle of the residential area, largely unused and in danger of collapsing. In 2006 the conceptual planning for converting the building into an Energy Bunker began, and 2010 saw the first static tests carried out. Safety, restoration, and conversion tasks on the bunker could only begin in 2011. The total cost of the work amounted to €26.7 million. As a flagship project, it was funded by the European Regional Development Fund (ERDF) and the Hamburg Climate Protection Concept.

The clients are the IBA Hamburg (restoration and expansion of the building) and HAMBURG ENERGY (energy supply). As part of a joint opening ceremony Uli Hellweg and Dr Michael Beckereit have now unveiled the IBA plaque and the ERDF sign.
