CSH Case Study Hamburgto the project
“Am Inselpark 1” is the address of the igs Centre, the first of IBA Hamburg's three Hybrid Houses to be completed, and the first new building in the emerging Wilhelmsburg Central district. With its high-quality design, low energy consumption, and versatile options for use, the igs Centre will set new standards.
Five architecture firms were invited to design a modern building that met high energy efficiency and interior versatility standards. The competition-winning design, submitted by NÄGELIARCHITEKTEN, Berlin, was initially built for use as the administrative offices and visitor centre for the adjoining International Garden Show Hamburg (igs), which ran from April to October 2013. The IBA also used one exhibition room in the igs centre from October 2011 to March 2013.
The four-storey building stands on concrete pillars sunk into a mound within the park, which also contains the ground floor and the exhibition areas. Up until the end of 2013 they housed not only the igs offices, but also one apartment and a separate office unit.
Convertible, Green, and Sustainable
After 2013 the first cycle of the building’s use as an exhibition space will come to an end. Due to its underlying hybrid concept the igs Centre will, however, offer many opportunities for mixed residential and work-related use, or may serve as a home for people of all ages.
The ground floor, which currently houses the exhibition areas, can be divided into large or small office or commercial units in a relatively simple and resource-efficient way. A system of supports and adjustable structural elements ensures that the upper floors can also be divided up to adapt to the changing needs of the inhabitants. Offices can be converted into apartments, and then back into offices. Each of the ten units is in a U-shape arranged around an atrium. These atria not only allow daylight to pour into the depths of the building all year round, but can also be opened up, thus serving as recessed balconies.
A Clear Sustainability and Energy Concept
The heat supply for the igs Centre comes from a mix of local heat provided by the Wilhelmsburg Central Integrated Energy Network, and is regulated by a heat pump. In winter the energy is extracted from the ground, while in summer it is transferred back into the ground via a reverse process. The heat pump is turned off during the summer months and the energy is fed into a cold storage system, which prevents the building from overheating. The roof of the igs Centre is covered with greenery, just like the mount on which it is built. The building management system ensures that there is an appropriate balance between heating and cooling at all times.
The igs Centre has been awarded a silver seal of approval by the Deutsche Gesellschaft für Nachhaltiges Bauen (DGNB) for its sustainability and energy concept.
