2. Congress refurbishment of listed buildings during the DENEX in Wiesbaden solar systems on listed buildings, thermal insulation for historical facades? -Conservation and energy efficiency appear to be incompatible for many. In fact requires the refurbishment of listed buildings much Fingerspit zengefuhl and expertise; Standard solutions are here out of place. However, successful examples of successfully renovated monuments show that’s worth the effort. Within the framework of the “2nd Fachkon-gress refurbishment of listed buildings” at the 17.11.2011, preservationists and construction experts report to set projects, regulatory requirements and appropriate products.

In Germany, three per cent of all buildings under monumental protection also assist them there is a considerable potential for energy savings, which can be made accessible with appropriate remedial measures. Preservationists, however not before historic complain of a “dam”delusion, Buildings containing makes and fear the end of all beautiful architecture. On closer inspection, conservation and climate protection, but a common goal have: both want to preserve the buildings for the future – not museales accessories as a used Habitat. Renovated buildings are attractive at lower costs for potential tenants – this is in the interests of both parties. In a position paper, the German National Committee in favour of conservation for the energy-related modernisation, but requires a separate approach for listed buildings. Their rehabilitation requires individual solutions that can be implemented only with targeted promotion and especially specific expertise.

Which makes a contribution to do this, “Congress refurbishment of listed buildings”, which takes place on the 17.11.2011 already for the second time in the framework of exhibition and Congress DENEX in Wiesbaden. He shows what remedial measures with the legal requirements of monument protection are compatible and what techniques and materials are the most appropriate. Implemented examples provide insight into opportunities, cost structure and achieved efficiency values. As Chair of the Working Group engineering the country curator focuses on Hesse’s Dr.-ing. Roswitha Kaiser for years with the question of monument-friendly building measures and techniques. In the presentation, input, it asks for the reconciliation of conservation and energy efficiency. Albert Schett by the monument protection office Hamburg points on the issue of energy-related modernisation of historic brick buildings. Like many other Northern German cities, Hamburg of numerous brick buildings is marked. Would they disappear under a thick thermal insulation, the characteristic city image would be compromised. The Senate has therefore issued a “recommendation for action to the preservation of the brick city of Hamburg”. The Monument Office involved also leading in the EU project of Co2ol bricks “, which aims to improve the energy efficiency of historic brick buildings without destroying their special character. Specifically The engineer Prof. Axel C. Rahn considered industrial monuments in his presentation. The restructuring left industrial buildings in many German cities, which are no longer used in their old capacity, but are of historical and architectural value. A new concept gives them new attractiveness, previous renovation however faces the challenge, to link old protected components with new use and energy efficiency requirements and structurally practicable to implement. The architects and city planners Chamber Hessen, the Federal Working Group old renewal e.V. as well as the competence centre Hessen raw materials (HeRo) e.V. support the Conference as. 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 the Rhein-Main-Hallen in Wiesbaden, Germany. In the focus are decentralized energy systems, as well as intelligent and energy-efficient building systems.
