During planning, a minimum use of building technology was emphasized. The foyer is regulated in the summer via cross-ventilation by means of night-time cooling. Large canopies on the fully-glazed entrance facades serve as natural shading. All lounges have large windows for natural lighting. All windows were arranged so that overheating of the interior can be ruled out and no technical cooling is necessary.
The material wood is visible in the interior and regulates the indoor climate by absorbing and releasing room humidity. Monitoring monitors the comfort of the indoor climate.
The heat energy concept is based on an air heat pump and a surface heating system. Due to the component-activated base plate in the exhibition area, it was possible to dispense with an additional floor structure here. The lighting concept is based on LEDs. The energy concept is supported by a 8400 kWp photovoltaic system, which supplies electricity to two e-bike charging stations in addition to the building. To increase self-consumption and to be able to use self-generated electricity at evening events, the system is supplemented by a 13.5KW electricity storage. Perspectively, the PV system can be expanded. This would turn the building into a Plus-Energy-Building.
Renewable, pre-elemented and flexible: The non-renewable building materials were only used in the earth-touched areas. From the top of the floor slab, the solid wood construction could be completed in only four months due to prefabrication of the building elements. The material wood stores C02 in the long term. The column-free structure spans the exhibition and event area and thus allows maximum flexibility. The curtain wall enables a complete unmixed disassembly of the construction elements. The aluminum used is 100% recyclable and the renewable raw material wood can either be reused or thermally recycled. In the entrance area, an “old” road stone found during excavation was also recycled and reinstalled. Thanks to the photovoltaic system, the building also generates its own energy, which supplies the e-bike charging stations with electricity.
The building therefore received the first AktivPlus certificate for non- residential buildings in Germany.
