IBA HAMBRUG - Smart Materials


28.05.2009 - IBA and ARCH+ WORKSHOP for the IBA 2013, Hamburg

More than 60 architects, engineers, scientists and designers meet to discuss together with the IBA organization and the magazine ARCH+ about smart materials and their possibilities and advantages for the building industry.

One of those new smart materials is UHPC: High performance with high-tech methods, produced with local raw-materials, extremely durable and sustainable. 56% raw-materials and 30% energy could by saved by using UHPC for constructions. This comes with a CO2 reduction up to 32%. The G.tecz-UHPC is the new outstanding material for sustainable constructions, facades and design-objects.

Well-Tech AWARD 2009

08 / 07 / 08 - Milan, Italy

The 'Membrane Concrete Grid Shell' construction (MBGT) is nominated for the Well-Tech Award 2009.
The construction system combines new technologies like high-tech cement bounded materials with traditional pneumatic membrane formwork systems to build large concrete grid shells. With this system, large concrete shells could be set-up within 7 days. One application field could be emergency accommodations in disaster areas. Fast set-up, cost effective, stable.
The system was developed at the University of Kassel (Faculty of Architecture, Dept. Structural Design) by Gregor Zimmermann. G.tecz is now further developing this system. With modifications facade systems, furniture, art objects or structure elements could be designed.


G.tecz is member of the entrepreneur board at the University of Kassel

... entrepreneur teams from the universities often arise in the context of research and therefore are science orientated during the early start-up phase. At the same time, at this stage a high support is required. This is where the 'incubator' offers suport with equipment, consultancy, coaching and mentors. An important role is played by the entrepreneur Council: Successful and experienced entrepreneurs and founders are promoting the incubator not only financially but also with advices. Since 2006, these companies are Biocatering Marbachshöhe, carts Real Time Solutions GmbH, Diebel Speditions GmbH, Kasseler Sparkasse, Meister AG, Müller und Partner, Quality for Success GbR, s.a.d. System Analyse und Design GmbH, SMA Technologie AG, Volkswagen Coaching GmbH, Von Waitzische Beteiligungen GbR, Wintershall AG. In the year 2008, the companies OctaVIA AG, E. ON AG and GTECZ came along. ... [citation: UniKasselTransfer]
