International Rosenheim Window and Facade Conference 10 and 11 October 2013

What has clever Mr Fox and his den to do with this year’s Window and Facade Conference and the motto “Safety/security and comfort – better quality of life”? Quite a lot! What seems to come naturally in the animal kingdom requires much hard work in a human-designed environment.

Aspects that make living more comfortable, safe, secure and healthy are the focus of the Rosenheim International Window and Facade Conference from 10 to 11 October.Speakers will report on the multiple advantages of modern window and facade systems, for example good daylight, better sound insulation and better security. In addition, the program of course also includes information on new technology, standards (DIN 4108, DIN 18008, DIN 4109, DIN 68800 etc.) and regulatory instruments, such as the new EnEV (Energy Conservation Directive), MBO (Model Building Code) and BauPVO (Construction Products Regulation). There will also be practical information on installation issues, on designing ventilation systems and on preventing the formation of condensate.

These days, the use of energy-conserving building components has become standard in the building industry; this is borne out by the volume of grants provided by the state subsidy system (administered by the KfW) and the growing proportion of windows with triple glazing. It is no surprise, therefore, that there is increased interest in aspects that make homes healthier, more comfortable and secur/light to improved sound insulation, good air quality through natural ventilation through to improved burglar resistance. There have been significant changes in the standards and technology that are important to window and facade experts.

Then there are also the new rules for CE marking which apply under the Construction Products Regulation introduced on 1 July, and which are of crucial importance. Prof. Christian Niemöller (SMNG Solicitors) reports on practical experience to date and will present practical case studies from companies, the law courts and market surveillance. The other relevant changes will be presented in 8 sessions at the Rosenheim Window and Façade Conference.

In Session 1, “Energy turnaround”, Andre Hempel (BMVBS) illustrates the current status of EnEV 2014 and risks an outlook over the stricter new version expected in 2016. Dr. Martin H. Spitzner (ift Rosenheim) provides practical tips to window manufacturers on how to provide the evidence of thermal protection in summer required under the EnEV in a simple way, and how to select suitable forms of shading.

In Session 2, “Refurbishment”, Christian Wetzel (Stuttgart University) presents simple cost-efficiency calculations and how to use them successfully when advising clients, and Martin Heßler (ift Rosenheim) has tips on how to avoid condensate and mould formation so as to prevent resulting damage in existing and new buildings.

Session 3, “Glass”, presents interesting technical developments in glass manufacturing which make it possible to optimise the construction of windows and facade systems. The results of the ift research project “Weight of insulating glazing units (IGU)” are eagerly awaited and will be presented by Norbert Sack (ift Rosenheim). Another research project has analysed the suitability for purpose of structural glazing facades after 25 years of long-term testing. Karin Lieb (ift Rosenheim) will illustrate the possible consequences for modern glass construction. Prof. Dr. Geralt Siebert (University of the Armed Forces) will provide information on the effects of the new glazing standards (DIN 18008 f), the use of glass in windows and doors and ways of simplifying verification and its procedure.

In Session 4, “Market and trends”, Prof. Dr. Runa T. Hellwig (Augsburg University of Applied Sciences) will demonstrate how to improve room climate and user-friendliness through better sound insulation, ventilation and daylight. Ulrich Tschorn (VFF) will summarise the arguments in the current debate on the cost-effectiveness of modernisations and energy upgrades, and Prof. Dr. Ulrich Bogenstätter (Mainz University of Applied Sciences) will give an insight into the workings of the “giant refurbishment machine” of the housing industry and what the criteria for commissioning replacement of windows are.

In Session 5 “Developments for the future”, Ministerialrat Hans Dieter Hegner (BMVBS - Federal Ministry of Transport, Building and Urban Development) will explain the role of windows and facades when upgrading a Passivhaus to a Plusenergy house. Dr. Jan Wurm (Arup) will introduce photobioreactors in facades for yielding energy and other visionary technologies for the building envelope.

Session 6, “Safety/Security”, is dedicated to security aspects of windows and entrance doors. Jens Pickelmann (ift Rosenheim) will provide information on the changed requirements for mechanical burglar resistance and how to meet them cost-efficiently and in compliance with the standard. Dr. Gerhard Wackerbauer (ift Rosenheim) will discuss the background, concepts and issues in construction law relating to the reaction to fire of windows and facades, for example how to comply with the requirements for “hardly flammable” and “non-combustible” materials.

In Session 7, “Developments in construction”, Dr.-Ing. Odette Moarcas (ift Rosenheim) will explain how to correctly implement DIN 68800 “Protection of timber” and will provide compelling arguments for the discussion with architects and building owners. Jörn P. Lass (ift Rosenheim) will talk on the subject of quality strategies for plastic windows and the implementation of the new RAL 716 quality label. Michael Müller (ifo – Institute for Surface Technology) will give details of how to implement DIN EN 1090 “Steel and aluminium structures” efficiently and in compliance with the standard.

Session 8, “What’s new in construction legislation” will provide information on changes in construction law relevant to window and facade manufacturers. Klaus-Dieter Wathling (Principal Building Control, Berlin) will analyse current changes in fire safety, escape routes and accessibility. Practical sound insulation in construction and the effects of the amended DIN 4109 with its new requirements, characteristic values and application rules will be introduced by Bernd Saß (ift Rosenheim). Both construction law and the BauPVO contain much stricter requirements regarding accessibility – Robert Kolacny (ift Rosenheim) will present technical solutions and their limitations.

As always, the ift Rosenheim will keep in close touch with practical issues; in four workshops, ift experts will provide practical information on technology and standards, for example

▪ how to benefit from tax concessions and subsidies to offset the cost of energy upgrades;

▪ how to implement, in a simple way, the new CE marking requirements and those of the Construction Products Regulation;

▪ how to install and seal windows simply and in accordance with the state of the art, also in thermal insulation composite systems;

▪ how to establish the possibilities and limitations of window ventilation, and how to produce a simple and legally correct ventilation concept. In addition, the ift experts will be available to answer individual questions throughout the two days.
