The Klimahaus Bremerhaven 8 ° Ost is a scientific exhibition house in Bremerhaven . It is located at the Old Harbor and is part of the Havenwelten ; its shape resembles a boat. The exhibition offers the possibility of a virtual journey around the earth in north-south direction on approximately the geographical longitude of the starting point, 8 ° 34′30 ″ east of Greenwich, and in the extension over the South Pole in north direction along the 171st to 172nd western longitude. The approximately 18,800 m² knowledge and experience world takes up the topic of climate and climate change in three exhibition areas . The operator is the Klimahaus operating company . Arne Dunker has been the director since 2004. Up to 2014 around 600,000 and in 2018 around 425,000 people visited the exhibition annually.

The Bremerhaven Climate House was opened on June 25th, 2009 by the Irish musician and human rights activist Bob Geldof . In addition to the existing North Sea Science Center, it is the second science center in Bremerhaven and, together with Universum Bremen , the third in the state of Bremen .

exhibition

“Flying Lore” at the Langeness station in the travel area

The exhibition area covers 11,500 m² and is divided into the three exhibition areas travel , perspectives and opportunities .

The travel area takes up the largest area with 4,800 m². Starting from Bremerhaven, the journey should lead along the eighth east longitude. Nine travel stations in eight countries represent the different climatic zones of the world. The travel stations are located on five different continents. The respective temperature and relative humidity are adapted to the local conditions. The Antarctic station has a temperature of around −6 degrees Celsius in the climate house, whereas the Niger station has a temperature of around 35 degrees Celsius.

Visitors to Switzerland as a travel destination can watch as a model how climate change is changing the lives of people in Isenthal . A few exhibition rooms further is the Cameroon travel stop with tropical warmth . The West African rainforest at night is illustrated by exotic smells and sounds. The Aleipata station on Samoa provides insights into the business of deforestation, downpours and green ravines . This is followed by an aquarium world with a view of a cultivated fringing reef made from living corals.

Stations are:

Isenthal , Switzerland
Seneghe , Sardinia , Italy
Kanak, Niger
Ikenge, Cameroon
Queen Maud Land , Antarctica
Satitoa, Samoa
Gambell, Alaska
Hallig Langeness , Germany

and back to Bremerhaven. The stations are not, as the name suggests, exactly on the 8th eastern longitude, which does not run through Bremerhaven itself (but about 38 km west), but roughly on the longitude of Bremerhaven, i.e. the circle that runs through Bremerhaven, runs through the south and north poles. The European stations are therefore almost exactly north and south of the starting point.

The original exhibition area Elements , which showed what influences the climate and weather, how individual phenomena arise and how the complex overall system is connected, was closed in 2012. In 2013, the Elements exhibition area hosted the special exhibition Creatures of Prehistoric Times - The Limits of Adaptation , which showed replicas of dinosaurs and living reptiles, amphibians and insects. The special exhibition should shed light on the consequences of climate change on flora and fauna and draw attention to current threats from climate change. The Offshore Center has been in this area since autumn 2014 . Sea - Wind - Energy housed, in which the topic of offshore wind energy is treated. The exhibition area was initiated by the Bremerhaven development company Alter / Neuer Hafen BEAN and was realized with funds from the State of Bremen and the European Union as well as with support from the wind power industry.

The perspectives characterize the second exhibition area, which will deal with the climate in the past, present and the effects on the future. Findings from climate research are presented here.

In the third exhibition area, the opportunities , the visitor is shown options for action. There are themed chambers for playful testing to reduce CO ₂ emissions in everyday life.

Each exhibition area is designed independently of the others.

Courses offered

The Klimahaus sees itself as an extracurricular learning location . In the exhibitions, visitors can research weather phenomena and the background to climate change and learn how climate protection works. The house creates materials for school classes and offers special tours.

patronage

With the assumption of patronage by the then Federal Environment Minister Sigmar Gabriel and the support of the project from politics and science, the socio-political relevance of the topic of the Climate House in Bremerhaven should become clear.

In 2013, Barbara Hendricks took over the patronage as Federal Environment Minister and visited the Klimahaus Bremerhaven on his 7th birthday in 2016.

Other institutions and companies are involved, including the Alfred Wegener Institute for Polar and Marine Research, the Max Planck Institute for Meteorology and the German Weather Service .

Builder, construction development, operator

Working on the Climate House (October 2008)

The building owner is the city of Bremerhaven. It has assigned the task to the subsidiary Bremerhaven Development Company Alter / Neuer Hafen (BEAN).

The climate house is a joint project of the city of Bremerhaven, the state of Bremen and the private operator. The public sector is financing the investment of 70 million euros. The initiators Petri & Tiemann then take over the operation and the associated risk. The Klimahaus operating company was founded as the operating company.

planning

At the end of 2000 the company Petri & Tiemann delivered a concept sketch of the Klimahaus project Klimahaus Bremerhaven 8 ° Ost . In mid-2001, the Bremen-based company submitted a comprehensive concept and feasibility study to BIS Bremerhaven . The architect Thomas Klumpp was initially the planner of the Klimahaus and the Eickworth-Iggena branch of agn Niederberghaus & Partner from Ibbenbüren in Bremen was responsible for the planning . The exhibition concept and design come from the Hamburg exhibition organizers Kunstraum Gfk mbH .

The planning office agn writes about the draft:

“The building geometry does not follow any mathematics, even if the eye thinks it perceives differently: It is by no means an ellipse, circular arcs or the like, but a completely free shape. Inside, too, the structure of the Klimahaus largely rejects classic architectural terms such as storey level, wall or ceiling. Instead, there is an inner spatial continuum made up of offset levels, galleries, stairs and ramps. "

BEAN has handed over the task of overall project control for the construction work at the Old / New Harbor to the Städtische Wohnungsgesellschaft Bremerhaven , (STÄWOG), which moderates the coordination between interior design and building construction and monitors adherence to the schedule and budget. The financing of the construction project is handled by the Bremerhaven Society for Investment Promotion and Urban Development mbH (BIS). The project management was the city-building Bremerhaven , a proper operation of the city of Bremerhaven.

execution

The climate house was originally supposed to open in summer 2007. Since the city of Bremerhaven had to re-tender the construction work in the meantime, this was delayed. The construction costs of over 40% are said to have been exceeded because of the increased world market prices for steel. The city of Bremerhaven will probably have to bear the construction cost overrun. Around 70 million euros were invested in the climate house from funds from public budgets ( GA funds and ERDF funds ).

Environmental and climate protection

Due to the constant maintenance of the air-conditioned rooms and aquariums as well as the necessary cooling of the building complex, the climate house has a considerable energy requirement. Therefore, at the beginning of the project development, there was a detailed analysis of the building use and the exhibition with the aim of limiting the energy requirement as much as possible and creating primarily environmentally friendly air conditioning concepts for the provision of energy. Exact figures on the energy consumption of the house are not publicly available. The Klimahaus Bremerhaven 8 ° Ost has to meet part of the energy requirement for the 37 levels with energy from conventional sources.

Cooling and heating

To ensure that energy is used in an environmentally friendly manner, the natural circulation of indoor air and solar radiation are used for ventilation and air conditioning. In order to be able to make better use of the available natural resources, the technology of concrete core activation for room temperature control was used. The natural thermal storage effect of the concrete is used. Another energy supplier that is used here is near-surface geothermal energy . For this, 464 piles out of a total of 770, which are anchored around 20 m underground and at the same time play a supporting role for the statics of the building, were used as heat exchangers . The diameter of the piles is up to 60 cm. They reach up to 25 m deep into the ground. They contain a total of around 21 km of plastic pipes through which a water- glycol mixture is pumped. These energy piles serve as heat exchangers for the ground and groundwater - for heating in winter and for cooling the building in summer.

Power generation

A monocrystalline photovoltaic system was installed directly in the insulating glazing in the roof of the plaza to generate a certain amount of the required electrical energy . With a total of 143 photovoltaic modules and an output of 35.7 kWp (annual electricity yield 30,000 kWh, corresponds to an annual electricity requirement of ten households), it is able to cover the electricity consumption of the "Opportunities" exhibition area. A secondary benefit of this system is the 80 percent shading of the interior, whereby a reduction in the energy requirement for cooling was achieved in the summer months.

The heat is supplied via district heating , which is generated in the Bremerhaven waste-to-energy plant. In order to also make a contribution to climate protection in terms of heat distribution, only electronically controlled dry-running pumps and high-efficiency pumps are used. These pumps adapt their speed to the changing load conditions of the system or the respective heating circuit, so that they consume significantly less electricity than unregulated pumps, which means that electricity savings of up to 80 percent can be achieved.
