By Sto AG, Markus Zwerger gives an overview of modern Hochleistungssdammstoffe in the Conference such as Aerogels, highly porous solids usually on silicate base, or vacuum insulation. The company Rockwool introduces its new Aero wool insulation, a combination of aerogel and rock wool, which has extremely low oxygen levels. Josef Mayr, Managing Director of Hofheimer Wohnungsbau GmbH, reported, as was used in a model project of major element insulation technology with vacuum insulation in existing rehabilitation. Modern facade technology ensures not only thermal insulation, it can also contribute to the optimum heat management of the building. Transparent thermal insulation for example, converts the incoming sunlight into heat – this also reduces heating costs. In addition, the permeability of the dam system ensures a pleasant diffuse lighting with daylight.

Markus Zwerger, Chief Executive Officer of the Association for transparent thermal insulation e.V., explains their action. Also PCM, phase changing materials, contribute to the heating and also cooling a building, because they trap heat in changing their physical appearance or leave them. Reported on the use of PCM in practice Martin Zeumer, responsible for research and technological development in the team of the TU Darmstadt, which designed for competition Solar Decathlon the surPLUShome. Through the integration of photovoltaic, facade wins an additional added value. Private electricity generation improves the energy balance of the building – as well as the attractiveness -, increases profitability and last but not least is a clear statement for environmentally responsible economies. Marco Schech, project engineer at Schuco, explains the advantages and possibilities of solar facades. The DENEX, trade fair and Conference for decentralized energy systems, intelligent energy distribution and efficient use of energy will be on 17th and 18th November 2011 in Wiesbaden.
