IBA DOCK: The floating climatic house

In the centre of the Hamburg metropolis there is a unique location which combines creativity, chances, contrasts and suspense. The Elbe islands of Wilhelmsburg and Veddel and the Harburg inland harbour are the venue and subject matter of the international building exhibition IBA Hamburg. Alongside the main themes of “metro zones” (development of inner city limits) and “kosmopolis” (development of the international community of a city) the IBA has written “City in a Climate Change” on its’ flags, with the goal of a CO2-neutral city development.On this backdrop projects are to be realised here which will enable renewable energies to find a wide area of usage. The importance of this theme should be expressed not only by the symbolic character but also by the transferability of the applied technologies to other projects. The IBA information centre, where building began in 2009, the IBA_Dock, was planned according to this motto; this signifies that air conditioning is possible without conventional energy sources such as oil and gas.

Casa Son Vida 1 and 2

Air conditioning design and ecological sustainability are self-evident requirements of contemporary architecture.

Together with the firm IMMOSOLAR, a concept was developed for 2 individual villas of the Cosmopolitan Estates in Son Vida on the island of Mallorca for the maximum usage of solar energy for the buildings’ heating systems, and for the economical and highly efficient operation of heat pumps at minimum cost. The system can be operated remotely using the PC-run IMMOSOLAR control concept.

The facts: 30m2 of collector surface, 2 heat pumps, 1x 29kW, 1x 22kW heat production; geo-solar thermics: 1000m deep drillings.
The IMMOSOLAR system within the houses ensures that the air conditioning is in perfect harmony with people and environment. The low temperature heat surfaces produce a unique comfortable air conditioning. The use of solar and geo-solar thermics takes care of the environment through its’ sustainability. The solar collectors are built in to the building in a manner that makes them practically invisible. IMMOSOLAR spoke with Mr. Michael Struck, coordinator of the project developments on the Cosmopolitan Estates in Son Vida.

The largest solar boat in the world and Germany's largest floating CO2 neutral building in Hamburg

Solar autonomy: Innovative research projects focusing on the use of solar power

The “IBA at Work” exhibition at the floating IBA DOCK was opened on 6 May in 2010, the year that marks the middle of the seven year long IBA exhibition based in Hamburg. The world’s largest solar boat, TÛRANOR PlanetSolar, sailed in for the event. Ambitious projects, such as these, prove that solar autonomy is possible where buildings and mobility are concerned. IMMOSOLAR came up with the innovative energy concept for the IBA DOCK, and as a partner in the PlanetSolar project, the company is also involved in the area of solar mobility.
